What Are the Standard Mattress Sizes, and How Do You Pick One?

So, what are the different mattress sizes, and how do you know which is right for you? Most mattresses follow standard dimensions, such as king, queen, and twin, so no matter where you purchase it, the length and width will always be the same. These universal sizes make it easy to find a compatible bed frame, bedding, and accessories. However, some mattress sizes are less common than others, and the right choice depends on your unique needs.
For example, the best bed for couples may be the Queen-size mattress, but if extra space is a priority, a king or a California king could be the best option. For children, sizes range from toddler beds to twin and twin XL, depending on their age and room size.
Beyond the standard mattress sizes, several other factors play a role in finding the perfect fit:
- Bedroom space: A king-size mattress may not fit a smaller bedroom, and even queen-size or full-size mattresses can limit floor space. Measure your room and furniture layout before deciding.
- Each person's height: If you’re sleeping multiple people to a bed, you’ll need to know what the different mattress sizes are and which will work best. Those over six feet tall will likely find king, queen, and XL mattresses more comfortable due to their extended length.
- Kids and pets: If you share your bed with children or pets, a wider mattress like a queen or king gives you more space to move comfortably.
- Budget and availability: Less common sizes, like California king and twin XL, can be pricier and may have fewer bedding options than standard mattress sizes like king or twin.
- Mattress height: While the sizes of king mattresses and other standard beds are consistent in width and length, their height ranges from 8 to 14 inches. Consider a higher-profile mattress or an adjustable box spring if you prefer a taller bed.
California King Mattress Size (72" x 84")

The California King mattress is one of the largest mattresses available, measuring 72 inches wide by 84 inches long. While it is four inches longer than a standard king-size mattress, it is also four inches narrower, making it a top choice for taller individuals who need extra legroom. If you're over six feet tall, this mattress can prevent your feet from hanging off the edge and give you a more comfortable sleep.
Beyond height considerations, the California King is a great option for those who share a bed with pets or prefer extra pillows at the head. Additionally, it can be a better fit for narrower bedrooms where a standard king-size mattress may be too wide.
That said, California King mattresses tend to be less common than traditional king sizes, making bed frames, fitted sheets, and bedding often more expensive and difficult to find than standard king-size options.
If you're looking for a mattress that accommodates height while still fitting in a narrower space, the California King can work as long as you plan ahead for bedding and accessories.
King Mattress Size (76" x 80")

A king-size mattress is one of the most spacious and comfortable options, measuring 76 inches wide by 80 inches long. It provides over six feet of width, making it ideal for couples who want plenty of room to move freely during the night. Whether you enjoy stretching out, reading in bed, or sharing space with pets, a king-size mattress offers ample comfort without feeling cramped.
One of the most significant advantages of a king-size bed is its wider availability of frames, sheets, and bedding accessories compared to the California King. With more options at typically lower prices, you have greater flexibility to choose a style that matches your existing home decor style. The wider mattress also leaves more room to add decorative elements, such as pillows, blankets, and kids' stuffed animals, without limiting your sleeping space.
However, the size of a king mattress can be a drawback in smaller bedrooms. It requires significant floor space and may limit where to place other furniture. Before purchasing, double-check your room's dimensions to guarantee you'll still have at least three feet of walking space in all directions for a comfortable, functional layout.
Queen Mattress Size (60" x 80")

A queen-size mattress is one of the most popular choices for couples and individuals alike, measuring 60 inches wide by 80 inches long. It offers the same length as a king-size bed but is 16 inches narrower, balancing space and practicality. This still provides ample space for restless sleepers to move around at night without filling the entire bedroom.
Many couples find that the queen mattress meets their needs without the added bulk of a king-size bed. Even with kids, pets, or extra pillows, a queen-size bed can comfortably accommodate multiple sleepers while maintaining the space in the bedroom. Due to its more compact size, a queen mattress can easily fit in most bedrooms, so it’s a versatile choice for various living spaces.
Another advantage of a queen-size mattress is its affordability and availability. Like king and twin-size options, queen-size sheets, bed frames, and accessories are widely available and often more budget-friendly than California King or King-size alternatives. Whether you want a minimalist setup or a plush, cozy aesthetic, a queen bed provides plenty of customization options to match your style and comfort needs.
Full Mattress Size (54" x 75")

A full-size mattress is a practical and budget-friendly option that measures 54 inches wide by 75 inches long. While slightly smaller than a queen bed, it still provides plenty of comfort, especially for solo sleepers or couples who don't mind a cozier sleeping arrangement.
For smaller bedrooms, a full mattress perfectly balances sleeping space and room layout. It allows for an adequate walkway on either side of the bed and makes a smart choice for apartments, guest rooms, or studio spaces where every inch matters. If you frequently move or rearrange your furniture, a full bed's lighter weight and compact size also make it easier to handle than larger mattress sizes.
Although two people can share a full mattress, it may not provide enough space for restless sleepers or those with pets who like to sprawl out at night. However, for single sleepers, a full bed creates an ideal balance of space and coziness, letting you move comfortably without feeling lost in a vast bed.
Standard full-size mattresses and bed frames are also more affordable than queen-size mattresses. So, if you're bed-shopping on a budget, finding a full-size bed with pressure relief, memory foam, or other specializations in your price range will be easier.
Full XL Mattress Size (54" x 80")
A full XL mattress combines the best of both worlds, offering the width of a full bed (54 inches) and the length of a queen (80 inches). This makes it an excellent choice for taller individuals who need extra legroom without taking up as much floor space as a queen or king bed.
The additional five inches in length can make a noticeable difference for those over six feet tall or anyone with pets who like to sleep at the foot of the bed. It's also a great middle-ground option for narrower bedrooms, ensuring a comfortable sleeping space without cramming the room.
Unfortunately, full XL mattresses, bed frames, and bedding are less common than standard full or queen options. This can make finding sheets, comforters, and accessories slightly more challenging and often more expensive. That said, if you need the extra length but don't have the space for a queen or king bed, the investment in a full XL mattress could be well worth it for your comfort and convenience.
Twin Mattress Size (39" x 75")

Twin beds are called "twins" because many hotel bedrooms would include two of these beds on each side of the room. At just over three feet by six feet, these mattresses are ideal for just one person. Plus, with as much foot space as full-size beds, twin mattresses should still fit most adult sleepers comfortably.
The main advantage of a twin mattress is its compactness, which makes it easy to fit in tight spaces. Whether for a small bedroom, a bunk bed, or a shared living space, a twin mattress is the perfect solution when space is limited. Many people slide the long side of their twin beds against the wall to maximize the floor space or use multiple twin beds as dividers in larger rooms.
The best part? Twin mattresses are an affordable option and widely available, making it easy to find bedding, frames, and accessories that fit. Whether outfitting a child's room, a guest area, or a studio apartment, twin beds offer plenty of flexibility to customize your space without sacrificing comfort.
Twin XL Mattress Size (39" x 80")

Like the full XL mattress, twin XL mattresses offer the same width as standard twin beds with the length of queen sizes. This tailored size makes them significantly more suitable for taller individuals or those who need more legroom while still maximizing floor space.
Twin XL mattresses are especially popular in college dorm rooms where space is limited, every inch counts, and comfort is a non-negotiable. The size of a twin XL leaves flexibility for room layouts while still providing a restful night’s sleep. Many college dorms use twin XL beds to accommodate students of various heights so everyone can rest comfortably.
Beyond dorms, twin XL mattresses are also a key component of split-king setups. When two twin XL mattresses are placed side by side, they create a king-sized sleeping area that allows couples to customize their side of the bed with different firmness levels or adjustable bases. This setup is perfect for those who want the flexibility of a shared bed with personalized comfort.
While twin XL mattresses and accessories are slightly more challenging to find than standard twin options, they can provide more customization than mattresses like queen and king beds. The added length makes them an excellent choice for those who need extra space without the bulk of a larger mattress, providing the best balance of comfort, space, and affordability.
Whether you're looking for a budget-friendly solution or need a more comfortable fit for taller sleepers, the twin XL presents the ideal compromise.
Toddler Mattress Size (28" x 52")

A toddler mattress typically measures 28 inches wide by 52 inches long, providing a secure and comfortable sleep space for young children transitioning to cribs. With a thickness of 5 to 8 inches, these mattresses provide the right amount of firmness to support growing bodies while maximizing bedroom space.
Most convertible cribs easily transition into toddler beds, allowing parents to reuse the same frame. Standard 27" by 52" mattresses fit most convertible cribs perfectly for an easy upgrade, though you should double-check your specific crib's dimensions before purchasing.
When selecting a toddler-size mattress, prioritize safety and durability. Opt for firm, non-toxic materials to support proper spinal development. Waterproof mattresses or high-quality mattress protectors help with inevitable accidents. Some parents also prefer hypoallergenic options for added protection.
Choosing the right toddler mattress ensures a smooth and comfortable transition from crib to big kid bed, helping your child get restful sleep in a secure environment.
Which Bed Size Is the Best for Me?
Choosing the right mattress size requires balancing personal preferences, room dimensions, and practicality. Before deciding, ask yourself the following questions to ensure the best fit.
Who Is Sleeping in the Bed?
The first step is determining who the bed is for. For instance, is the bed for you, a toddler, a teenager, or random friends and family members staying in your guest bedroom? If you're shopping for someone else, ask about their comfort concerns, such as needing more legroom or space for a pet.
Once you know who you're shopping for, consider all person-specific variables that may impact your decision, including:
- Body size: Taller individuals may need longer, XL-sized beds or wider beds with extra room to move back and forth.
- Sleeping habits: Light sleepers may benefit from more space, especially if sharing a bed.
-
Age: Consider future growth when buying for a child or teen.
Room preferences: Large beds can maximize comfort, while smaller ones preserve floor space. - Bed height: Some prefer low-profile beds, while others need space for storage underneath.
How Many People Are Sleeping in the Bed?
Buying a mattress for two people leaves you with many more factors to consider than a one-person bed, including each person's unique sleeping habits. So, what are the different mattress sizes for couples? Two light sleepers may be perfectly comfortable in a full-size bed, but two restless sleepers may need something a little wider, such as a king or queen-size mattress. Even if only one person moves frequently, a wider bed can ensure better rest for both partners.
Additionally, think beyond just the couple. Do pets or children often climb into bed? Parents and pet owners may need to invest in a wider or longer mattress, such as a king or full XL. Parents, in particular, may want to invest in a bed with ample space to accommodate nighttime visitors.
For those with larger pets, Hawaiian king or California king mattresses offer extra legroom. Both sleeping habits and additional occupants can contribute to finding a bed size that maximizes comfort and undisturbed rest for everyone involved.
How Big Is the Room the Bed Is In?
You may understand your personal needs and preferences, but what are the mattress sizes that will fit in your bedroom? Your room's dimensions may be the ultimate deciding factor for your new mattress, as small or narrow spaces will limit your options.
Consider the following factors when visualizing your bedroom upgrade:
- Room dimensions: Measure your bedroom's length and width to determine how much space you have. If you've already picked a wall for your bed, measure the space along that wall and in front of it to ensure your chosen mattress fits comfortably.
- Other furniture: Bigger beds, such as California kings, may leave minimal room for other pieces of furniture like dressers, bedside tables, TVs, floor lamps, and laundry baskets. Measure the width and length of your other bedroom furniture to avoid overcrowding your living space.
- Walking space: Leave at least 30 inches (2.5 feet) of clearance around your bed to ensure easy movement. If two people share the bed, both sides should be accessible without squeezing between the furniture.
- Ventilation: Avoid placing your bed directly over floor vents, attic access panels, or electrical outlets that require occasional access. Blocking these features can impact airflow and even pose safety risks.
- Comfort and orientation: Think about how you want your bed positioned. Do you prefer to face the door while sleeping? Do you like watching TV before bed? Your habits may determine whether your bed needs to be centered, angled, or placed against a particular wall.
Remember that your new mattress may look larger or smaller than it does in its online photos, so you can't rely on your eyesight to ensure it fits. Take time measuring and recording your room's dimensions to avoid unwanted surprises later.
What Is My Budget?
Your budget may be a crucial deciding factor when choosing mattress sizes, especially if you're upgrading your entire bed. Larger mattresses like kings typically cost more than smaller options, such as twins. Additionally, less common sizes, like twin XL, full XL, and California king, often have higher price tags due to their rarity.
Mattresses with distinct specializations, such as zippers, innerspring, latex, or memory foam mattresses, also tend to cost more than standard mattresses. If you have a limited budget, consider prioritizing a high-quality full-size mattress over a basic queen to balance comfort and cost.
If upgrading your entire bed rather than replacing your mattress, you should also consider the cost of all necessary bed accessories. Remember that larger and less popular mattress sizes will also require you to spend more on your entire bed setup. Bed essentials to budget for include:
- Bed frames
- Box springs
- Headboards
- Mattress toppers
- Mattress covers
- Sheets, comforters, and bedding
How to Find the Right Bedding for Your Mattress
You don't need to memorize every mattress size to find the right bedding; you just need to know your mattress's dimensions. Mattress measurements are universal across standard sizes, making it easy to mix and match brands, styles, and specializations. For example, even if you don't have a Beddy's mattress, you can still use Beddy's zipper bedding by selecting the correct size for your bed.
What Are All the Mattress Sizes That Work With Beddy's Sets?
Beddy's offers a wide range of zipper bedding and matching accessories, from twin XL fitted sheets to coordinating throw pillows. Our innovative design lets you zip up the entire bed, including the comforter. This makes it significantly easier to make the bed every day and remove it all when you need to wash it.
Beddy's zipper bedding is available in lots of fun styles and mattress sizes to match any bedroom space. For example, neutral-colored, king-size zipper bedding sets may be perfect for the parents' bedroom, while the kids' beds may need fun, printed twin-size sets designed for children. If you're furnishing a recreational vehicle (RV), Beddy's also offers bedding for different RV mattress sizes, including three-quarter corner beds.
Which Beddy's Mattress Is Right for Me?
Beddy's zipper mattresses offer unique features that differentiate them from other options. They include removable tops for easy cleaning, affordable replacement, and various customization choices. Most importantly, these removable features won't restrict your comfort, so you’ll feel like you're sleeping on clouds every night.
The best Beddy's mattress for you will depend on your needs, as each model offers different features. For instance, the ZipLuxe mattress is ideal if you prioritize customization, while the ZipClean mattress is the most affordable and straightforward to clean.
What Are the Standard Mattress Sizes With Beddy’s?
Beddy's mattresses are available in the following standard sizes:
- Twin (39" x 75")
- Twin XL (39" x 80")
- Full (54" x 75")
- Queen (60" x 80")
- King (76" x 80")
ZipLuxe
The ZipLuxe Dual Comfort Mattresses let you customize your bed's surface to your precise needs. It features a flippable interior latex layer with soft coils on one side and firm coils on the other. Simply unzip the mattress top to easily switch between the two, allowing you to adjust your comfort level, whether you need back support or want to sink deeply into your bed.
Additionally, queen and king-size ZipLuxe mattresses let you alternate the firmness on each side of the bed. This personalization may be crucial for couples with differing preferences or those who need to adjust firmness regularly.
ZipClean
The ZipClean Mattress is Beddy's most affordable and is the best zipper mattress for easy cleaning. Its zippable top is moisture-resistant and made with reliable, sustainable materials like CertiPUR copper memory foam and natural PurLoft Wool.
Whenever an accident or spill occurs, you can simply zip off the top and toss it in the washing machine on cold. This makes the ZipClean mattress an excellent choice for children, pet owners, elderly adults, or anyone who enjoys snacking in bed.
ZipPure
Beddy's ZipPure Organic Luxe Mattresses are the best mattresses for health-conscious sleepers who prefer eco-friendly materials. Made with organic wool and cotton, this mattress offers a soft and safe place to rest while supporting your commitment to sustainability.
Although the organic bedding materials may be a bit more challenging to clean than other zipper mattresses, a mattress pad can help prepare for potential messes. Like the ZipLuxe, the ZipPure features a flippable latex interior that lets you alternate between soft and medium-firm coils. For queen and king-size options, the ZipPure is customizable on both sides for couples with differing sleep preferences.

What Is a Zipper Mattress?
Zipper mattresses combine Beddy's revolutionary zipper bedding with high-end, specialized mattresses. The zipper tops allow you to easily remove and clean the exterior covers without cleaning the entire mattress. This makes dealing with accidents, spills, and other messes relatively pain-free, regardless of the mattress size. Plus, you can affordably replace the zipper top without purchasing an entirely new mattress.
Beddy's specialized zipper mattresses also let you customize your mattress to your needs and comfort preferences, even when sharing the bed. For example, ZipLuxe mattresses feature adjustable latex layers that allow you to alternate between soft and firm coils. This means you can set the bed to be firmer on one side and softer on the other, accommodating each person's preferences or needs on any given day.
Do Beddy's Mattresses Have a Warranty?
Beddy's mattresses feature ten-year non-prorated warranties, covering the cost of eligible repairs and replacements. Additionally, all of our products feature 365-day tiered manufacturer's warranties. These warranties give your bedroom upgrades ample protection throughout their lifetimes.
It's important to double-check your product's warranty terms when purchasing to avoid voiding the warranty or compromising the integrity of your zipper mattress. For example, ZipLuxe mattresses can't be placed on box springs or slats wider than three inches apart.
How Tall Are the Different Mattress Sizes?
Standard mattress sizes like twin and king generally have consistent length and width measurements, but their heights vary by product and manufacturer. Most mattresses are only about eight to fourteen inches thick, meaning one mattress could be nearly twice as tall as another, even if both are the same size.
Always double-check your mattress height before purchasing to avoid any surprises upon delivery. Any mattress with at least ten inches of thickness is generally considered enough to support an adult comfortably, but some sleepers may prefer a thicker mattress for additional comfort. Taller mattresses, especially specialized ones, can offer better support depending on your physical needs.
When considering mattress height, think about how tall you want your new bed to be. Some people prefer having taller beds that they can comfortably sit on throughout the day, while others prefer shorter beds that occupy minimal space. Consider what works best for the space and the person using the bed. Remember, you can invest in a taller bed frame or a platform bed if your ideal mattress isn't tall enough.
Is Twin XL the Same as Full?
No, twin XL mattresses are not the same as full-size mattresses, as both beds have quite different dimensions.
Full beds measure 54 inches wide and 75 inches long, offering enough space for a single adult to sleep comfortably or even couples who don't mind a cozier fit. They are essentially compact queen beds that are great for small to medium-sized rooms where maximizing space is important.
On the other hand, twin XL beds are 39 inches wide and 80 inches long. While they provide the same amount of space as twin beds from side to side, they are longer, making them a better choice for taller individuals. Twin XL beds are beneficial in smaller bedrooms, guest rooms, or for anyone who needs extra length but doesn't have space for a full-size bed. They're also great for pet owners, offering more room without taking up as much floor space.
What Are the Dimensions of a Double Mattress?
A full-size mattress, also called a double mattress, measures 54 inches wide by 75 inches long, though height varies depending on the brand and model. Full mattresses are often considered a good middle ground between twin and queen-size beds, offering enough space for solo sleepers or couples who prefer to sleep close together.
However, the length of a full mattress can be a downside for taller individuals, as it only offers about six feet from head to toe. This might lead to discomfort for those over six feet tall, with their feet possibly hanging off the edge of the bed. A full XL mattress, which provides a crucial additional five inches of legroom, could provide a more comfortable fit.
Can Two People Comfortably Sleep on a Full Bed?
Two people may be able to fit comfortably in a full bed, but it ultimately depends on personal preferences and sleeping habits. Full mattresses aren't as long or as wide as queen or king mattresses, which can make the bed feel quite crowded. Some restless sleepers may feel uncomfortable if they don't have enough room to move around, which can inevitably cause one person to feel like they're being pushed off the edge. Kids, pets, and pillows can limit your available space even more.
Still, upgrading to a queen or king-size bed may not be practical if your bedroom is too small. If your bedroom isn't large enough for anything more expansive than a full bed, consider investing in a full XL bed instead. These hybrid mattresses are just as long as queen mattresses from head to toe while maintaining the full mattress's width, offering an excellent alternative for tall individuals and pet owners.
Alternatively, some full bed owners have issues with one or both partners hogging up the bedding. This problem can easily be fixed by investing in a queen-size blanket instead.
How Does a Full Mattress Compare to a Queen in Size?
Queen-size mattresses measure six inches wider and five inches longer than full-size mattresses. This extra space can be essential for couples, especially those who need more room to move around at night. However, a queen bed may take up more floor space, which could be a concern if you have a narrow or compact bedroom.
On the other hand, full mattresses may be better for two light sleepers or adult individuals who want room to move around. Their smaller dimension allows for better furniture arrangement and more walking room, making them a smart choice for smaller bedrooms, guest rooms, or studio apartments.
Additionally, queen-size beds and accessories are somewhat pricier than full-size options due to their larger sizes. However, since both sizes are pretty standard, you'll find plenty of options for full and queen beds and bedding, while also making it easier to customize according to your style.
What Are the Sizes of a King Mattress?
King-size mattresses come in one standard size: 76 inches wide and 80 inches long. While the height varies by mattress, most king sizes are 8 to 16 inches tall, with some measuring 20 inches or more.
If the traditional king-size mattress doesn't fit your space or needs, specialized king-size mattresses offer different measurement options. For example, California king mattresses are 72 inches wide and 84 inches long, giving you extra leg space but less width. Check out Wyoming king, Texas king, and family bed XL mattresses for even larger mattress sizes built for families.
King vs. California King: What's the Difference?
King-size beds measure 76 by 80 inches, while California kings are 72 inches wide by 84 inches long. This makes California King beds four inches longer from head to toe and king-size beds four inches wider.
California king beds are ideal for taller individuals and pet owners, especially if you have a big dog that always sleeps at the edge of the bed. On the other hand, standard king sizes may be better for restless sleepers who roll and move around a lot at night. You should also consider your room's dimensions, as having a bed that's too long or wide could restrict your walking space.
What Are the Mattress Sizes Larger Than a California King?
While California king is the longest standard mattress size, various manufacturers produce a handful of larger sizes, too. However,, these larger sizes may not be practical for most bedrooms, and finding suitable bed frames and bedding can be challenging.
The most well-known mattress sizes larger than California kings include:
- Wyoming king (84" x 84"): These square-shaped beds measure seven feet on each end, offering nearly as much length as the California king with plenty of extra room on the sides.
- Texas king (80" x 98"): The Texas king bed is longer than the Wyoming king and the California king, though not quite as wide as the Wyoming king. It's a somewhat practical upgrade from the standard king for parents and pet owners.
- Alaskan king (108" x 108"): Extending nine feet on both sides, the massive Alaskan king bed creates a comfortable place for families to rest, especially with pets and kids. Most Alaskan king mattresses cost at least a few thousand dollars.
- Family bed XL (144" x 84"): Reaching twelve feet from side to side, this enormous bed is wider than it is long. It gives you the same leg space as a California king but with nearly twice as much room on each side.
What's the Best Way to Measure a Mattress?
Use measuring tape and work with another person to effectively measure your mattress on each side. Record the approximate width from side to side, length from head to toe, and height from bottom to top.
Your final numbers should fall into one of the standard mattress sizes below:
- Toddler - 28" x 52"
- Twin - 39" x 75"
- Twin XL - 39" x 80"
- Full - 54" x 75"
- Full XL - 54" x 80"
- Queen - 60" x 80"
- King - 76" x 80"
- California king - 72" x 84"
If you're considering a bedroom makeover or investing in a different bed size, take some time to measure the rest of your bedroom and furniture as well. Comparing these measurements to potential mattress sizes will help ensure a proper fit and maximize your space.
