Chart for Mattress Sizes
Selecting a mattress is a significant decision that will have a direct impact not only on your sleep but also on your health. The majority of customers consider comfort, material, and firmness as the main criteria; however, size is one of the basic factors that people often overlook. It is better to become knowledgeable about the different bed mattress measurements before actually making a purchase. This wise initial move ensures that you will have a new bed that not only occupies the designated space but also provides a sleeping area large enough for a good night’s sleep. The mattress length and mattress widths determine how comfortably you can stretch out, and are especially important for. The comprehensive guide will assist you in understanding the bed mattress measurements and will present all the sizes from the small Twin to the large California King.
Why Mattress Dimensions Matter?
Consumer choice is not the only factor influencing the decision regarding which mattress size to buy; practical considerations are also a key aspect, primarily dictated by daily life situations. Selecting the wrong mattress size may lead to a cramped sleeping space and an awkward bed arrangement in the room. Additionally, there may not be enough room for the mattress and bed frame together. The following aspects are of paramount importance:
Room Size: The mattress should do more than just fit the room like a glove; it should also look good in the room, and ideally, it should be the least dominant piece of furniture in the room. One very good rule of thumb that can be applied here is leaving at least two feet around the bed for movement—one foot on each side and at the foot of the bed.
Sleeper(s) size and habits: Your height, weight, and the fact if you sleep alone or with a partner will determine your choice. The restless sleepers or those sharing a bed need more space than a solitary, stone-dead sleeper.
Future Needs: Are you planning to move soon? Will there be a period when you will need to share a mattress with someone? If you do proper planning, then the need for a replacement will not be so soon as expected.
Budget: It’s hard to avoid the fact that the price of larger mattresses usually corresponds to that of bedding and bed frames of the same size. When buying, it is extremely important to take the overall price into consideration.
We have highlighted the standard mattress sizes to make the procedure easier, and you will have a clear understanding of the fitment of each size into your lifestyle and house. You can see a chart for mattress sizes below, which will help you choose the right mattress size.
Understanding the Mattress Size Chart
Determining a mattress size can be quite bothersome at times, but the standard mattress size chart really helps a lot. The leading mattress manufacturers in the US are more or less in agreement about the measurements, yet it is always a good idea to check the exact sizes one more time before placing an order.
Additionally, the range of thickness or height varies considerably from extremely thin, 6-inch mattresses to incredibly thick and comfortable 15+-inch mattresses. Height does not actually change the surface area, but it affects the overall height of your bed.

A Detailed Look at Each Mattress Size
Let’s delve into the mattress sizes in detail so you can make an informed decision.
Crib Mattress
The crib mattress is one of the top sleep aids for infants and toddlers, providing not only safety but also comfort at the same time. The crib mattress size that is most common is 27 inches wide and 52 inches long (68.5 cm x 132 cm), and it is able to fit almost any U.S. crib easily. The small and hard mattress supports spinal alignment and thus lowers the chance of a baby being smothered or caught, which is a major concern for infant safety. Only FOAM or INNERSPRING are the materials used to manufacture crib mattresses, which are the sources of their durability and longevity. Moreover, the idea of double-sided mattresses has been adopted by a few companies, which means that one side has a rough texture for a baby and the other side has a soft texture for a toddler; therefore, the mattress can be used throughout the child’s entire life.
Moreover, cribs usually come with waterproof or washable materials that make cleaning after diaper leaks or spills quite easy. The most important thing when purchasing a crib mattress is to make sure that there will be no more than a two-finger wide gap between the mattress and the crib sides. This rule takes care of all safety issues, and at the same time, it gives the baby the best feeding surface. To put it briefly, the crib mattress is a main contributor to the infant’s physical as well as psychological development in the first months since it provides a safe, welcoming, and clean sleeping environment. If the right choice is made, parents can have peace of mind knowing that their baby is sleeping safely and soundly without any issues every night.
Twin Size Mattress
The twin-size mattress is among the most frequently found bed types; it is small and suitable for just one person or for a small living space. The dimensions are 38 inches (96.5 cm) in width and 75 inches (190.5 cm) in length, which makes it a child’s, a teenager’s, or an adult’s mattress who likes to sleep alone and needs no extra room. Because it is the narrowest, a twin mattress can be in a small bedroom, a studio apartment, a dormitory, or a guest room, and the room will still look spacious as far as furniture is concerned. A twin mattress is most often found in children’s rooms as it can be used with bunk or trundle beds, which are space-saving and practical.
It provides one person a comfortable sleeping space, but a tall person may prefer the Twin XL (38 x 80 inches) as it is longer and more convenient. Besides, Twin beds have good market acceptance since the mattresses, bed frames, and bedding for this size are in high demand and therefore available in the stores; they are also cheaper than their larger counterparts. To sum up, a twin-size mattress is a great combination of comfort, economy, and practicality, hence the perfect choice for raising kids, singles, or any minimalists and space-saving sleeping solutions users.
Twin XL Mattress
A Twin XL mattress is a smart and adaptable option in bedding for singles who want to stretch their legs a little bit. It measures 38 inches in width and 80 inches in length (96.5 cm x 203 cm); thus, while matching the normal Twin in width, it gives 5 inches extra lengthwise, making it perfect for taller persons or kids who are growing.
The Twin XL is the most common mattress type used in college dorms, guest rooms, and small apartments. It brings a great sense of comfort and doesn’t take up much space. It is also ideal for split king configurations where two Twin XL mattresses are placed side by side to form a King-size bed, allowing each partner to select the firmness on their side.

Full Mattress
A Full mattress, which is also called a Double bed, is one of the most diverse mattress sizes and probably the most frequently used ones. The size is 54 inches or 137 cm wide by 75 inches or 190.5 cm long, which allows sharing a bed with more space than Twin mattresses, but at the same time is not too big that it takes up the whole bedroom or apartment.

A Full-size mattress provides an excellent sleeping area for one person and can accommodate a couple of small adults for a short time. It is particularly attractive to single sleepers who require the extra space to expand, roll, or sleep in different positions without being confined.

For laying out the bedroom, a minimum size of the room is 9 feet by 10 feet for a Full mattress to be laid. It is apt for the various arrangements of furniture, and it also gives a space that is enough for moving around and decorating. The Full mattress may be tight for two, but it is still a space-saving and budget-friendly solution that provides comfort. Its flexibility, price, and small size make it one of the most appropriate mattress sizes for people living in apartments, using guest rooms, or single sleepers looking for a combination of comfort and space efficiency.
Full XL Mattress
The Full XL mattress is a commonly preferred option for people aiming at getting a wee bit of space and sleeping comfort at the same time. It has quite a considerable size, the measurements of 54 inches in width by 80 inches in length (around 137 cm × 203 cm). This size is equal to the width of a standard full (double) mattress, but in length, it gives an extra 5 inches, which, among others, is most suited to taller people who require more leg space without having to switch to a queen or king size mattress.
The Full XL mattress size is really great in small bedrooms, guest rooms, studios, or dorms where space might be limited, and thus it is important to have as little ground space as possible. It is large enough for one person to sleep in it, relaxing, and also sometimes, if the situation demands two people to sleep in it, it can be done, although the bed might feel a bit crowded, so it is usually recommended for one person.
A queen mattress is 60 inches wide and 80 inches long, while a Full XL mattress is 54 inches wide and which is 6 inches smaller than a queen, but lengthwise it is the same. Hence, the people can savor the extra legroom of a queen mattress and still have the floor space saved up. It is also made the same way when it comes to the bed frames and bedding accessories that are specifically meant for the XL sizes. All in all, the Full XL mattress is a smart choice that does not compromise on the sleeping experience, and at the same time, it is a space-saving solution.
Queen Mattress Dimensions
The Queen size bed mattress dimensions are: 60 inches wide x 80 inches long. The queen mattress size is the most preferred in the U.S., and there are plenty of reasons for that. It accommodates a wide range of customers’ needs by providing room for the majority of couples and, at the same time, being suited for the most basic bedrooms. A queen is an extravagant upgrade for the singles, giving one the chance to stretch out. Size of Queen Mattress is 6 and 5 inches wider and longer than a Full respectively. The difference may not be much, but the quality of sleep may be hugely affected, especially for couples, if the beds are the same size, just with different widths. Each person has 30 inches of space, which is the main reason for having less disturbance and more movement. The combined ability to be cozy yet have enough coming and going space makes it a favourite in guest rooms as well as main bedrooms.
Olympic Queen Mattress
An Olympic Queen mattress is an extravagant but practical choice for horizontal sleepers who do not want to give up the sleeping width of a king-size but do not have the space for it. The dimensions of the respective mattress are, in inches, 66 by 80 (or in centimeters, 168 by 203), meaning it is 6 inches wider than a standard Queen mattress without any length loss. This feature makes it a great partner for those who want extra personal space between them, but are not eager to upgrade to King. For the Olympic Queen mattress, bedrooms with at least 10 feet by 10 feet dimensions are the best place.
This way, the mattress provides plenty of comfort and room for movement. It is great for taller or bigger people, couples with pets, and people who like sleeping on large beds but still want to leave some space in the room. Since it is a non-standard size mattress, bedding, sheets, and bed frames that fit this dimension will be harder to find, and in some cases, custom orders will be necessary. Nevertheless, for many sleepers, the width alone is the reason for their pleasant and comfortable sleep. Thus, an Olympic Queen mattress is the perfect compromise between a Queen and a King-size bed — it has both space and comfort. Besides, it is a not-so-expensive and a bit luxurious choice for those wanting to improve their sleep quality without the need to make a full-size bedroom redesign.

The King-size mattress is the embodiment of luxury and comfort for couples, families, and anyone who just loves to have the largest sleeping space possible. It measures 76 inches in width and 80 inches in length (193 cm x 203 cm) and provides an additional 16 inches of space over a standard Queen mattress. This makes each sleeper have a space similar to a Twin bed. Thus, enabling the users to stretch, to let kids and pets share the bed, or just to enjoy a spacious place for sleeping. A King mattress can be best placed in a very big master bedroom—at least 12 feet by 12 feet would be ideal—to ensure that there is no discomfort and that the furniture is placed properly. The large area of the bed guarantees the best support for all sleeping positions and the option of using split box springs or adjustable bases for extra convenience.
The couples are the ones who mainly benefit from the King mattress because it greatly reduces motion transfer, thereby permitting one partner to move around without bothering the other. It is also popular among families who have great times watching movies together or sleeping with their little ones. On the other hand, the King-size mattress will always be difficult to handle while moving or rotating; therefore, it will always be the case that the accessories, like sheets and bed frames, will be more expensive. Nevertheless, the King-size mattress will always be a symbol of comfort, space, and luxury in the top-tier position, providing an unprecedented sleep experience to those who can afford it in terms of space.
California King Mattress Size
A California King mattress has dimensions of 72 inches in width and 84 inches in length and is considered the largest one in the entire mattress market. It is often referred to as the biggest mattress available, but in reality, it is just a matter of size difference with the king mattress. The 84″ dimension of the length has a major plus point for people who are over 6 feet tall, since a regular bed would mean their feet would be hanging off most of the time.
The cal king mattress size gives up the standard king’s width of 4 inches for the sake of length. The bed will not be as wide as the standard king option, yet it is a longer bed that might be the right choice for tall couples or a long and narrow bedroom, as the standard king might be too wide. At last, the choice between a King and Cal King mattress will be a matter of personal preference for width or length.
Wyoming King Mattress
The Wyoming King is a portly and magnificent bed that is meant for total relaxation. Its dimensions are 84 inches wide and 84 inches long (about 213 cm × 213 cm), making it a square that is able to give one width and length beyond a standard King or California King. It is, therefore, a good option for couples who like the extra room, families who co-sleep, or pet owners who want their furry friends to share the bed without feeling squeezed.
The Wyoming King mattress guarantees that the sleepers will have more than enough space to spread out in any direction. By 9.5 inches wider and 4 inches longer than standard King (76 x 80 inches) and California King (72 x 84 inches), giving maximum comfort of width and equal length. Wyoming King Mattress Size does not mean that it cannot be accommodated in most of the master chambers, especially the ones that are spaciously designed.
Since the Wyoming King is an uncommon size, it is necessary to order the bed frame, sheet, and duvet covers for it specially, but the comfort and luxury that it bestows in return are certainly worth the hassle. The king bed is for those who adore unreal space and high-quality sleep experiences; it might even be said that the Wyoming King mattress embodies the virtue of largeness and the feeling of reformation into any bedroom.
Alaskan King Mattress
The Alaskan King mattress is the largest and most luxurious bed size available to offer probably the best comfort and sleeping space. Besides its unbelievable dimension of 108 inches wide and 108 inches long (approximately 274 cm × 274 cm), this incontestably oversized, square-shaped mattress provides a surface that is so large that it can easily accommodate two persons and a pet or a child, which is why it is considered perfect for family co-sleeping.

The Alaskan King is the best fit for tall individuals since 9-foot dimensions make it the most legroom in every direction, challenging standard or California King mattresses, where they all surrender.
But of course, owning an Alaskan King does come with its own set of challenges. First, you need a big room of at least 16 by 16 feet to let the bed area be clear and easy to move around. Secondly, custom bedding and other accessories, such as frames and foundations that cannot be arranged using standard sizes, will be needed. Still, the Alaskan King mattress, though costly, coupled with all the logistical demands, delivers a royal sleeping experience by blending space, comfort, and grandeur for those who want only the best in luxury sleep.

RV Mattresses: For trailers, mattresses usually have abnormal sizes (like a Short Queen RV) to use up the limited and unusual spaces.
How to Measure Your Room for a New Mattress?
The very first thing to do when buying furniture is to measure the room where the new pieces will be placed. Approximating the furniture size is not a good idea and is really not worth the trouble.

Outline the Bed: Before anything else, you need to decide on the size of the mattress you will be getting and its position in the overall floor plan. Besides, it is a good habit for the open sides of the bed to have at least 24-30 inches of walking space around.
Draw Your Path: Have you figured out how to get the mattress into the bedroom? Doorways, hallways, and stairs all play a part, so make sure the mattress and box spring foundation will go through without a hitch.
