What Is The Width Of A King Mattress

King Mattress Dimensions Are 76 X 80

What is the difference between a King size and a California King size mattress?

King size mattress dimensions are 76″ x 80″. King beds are growing in popularity. King mattress dimensions are about 16″ wider than a Queen bed. Both are about 80″ long. The Eastern King size mattress is the only bed to give each person the same width as a Twin bed. In fact you can push 2 Extra-Long Twin beds together to be the same size as an Eastern King mattress. This is a good way to have a versatile guest room . An Eastern King bed comes with one mattress and two half-width box springs to be more manageable when moving. Approx. width per person: 38″

Pros: This is the widest standard bed available. Roomy enough for 2 large adults. The 80″ length comfortably accommodates most people. Bed sheets are easy to find and are generally labeled simply “King”.

Cons: This is a very large mattress that may not fit easily up stairs or into smaller rooms. Taller people may prefer the California King instead with its longer length. All bedding is most expensive in king sizes, and 3 standard pillows or 2 king pillows are needed for this width.

How Wide Is A Queen Size Bed

The average width oftheQueen bed is 60″ or 152 cm.

The Pros and Cons of a Queen Mattress Size


  • The Queen Mattress Dimensions comfortably fit two adults.
  • The Queen Mattress is cheaper than a King or California King.
  • The Queen is also a generous size mattress for a single adult with pets or children.
  • As the most common mattress size, there are many different varieties and manufacturers.


  • The Queen mattress is not suitable for two adults and a pet or child. The King and California King offer plenty of room for a couple and pets or a child.

What Is A Split King Mattress

A split king size mattress is essentially two twin XL size mattresses combined together side-by-side on separate mattress foundations to equal the surface area of a king mattress size. Split king mattresses are ideal for couples with specific individual needs and preferences, along with people who frequently move and will have to transport their mattress.

Take a look at the size chart below to compare general mattress sizes:

76 x 80 or 2
California King 72 x 84

Typically, split kingadjustable beds work best for couples or people who sleep in the same bed. Each person gets their own personal space and you dont have to compromise on key mattress factors.

Additionally, there is little risk of motion transfer when the person you share a bed with moves in their sleep or gets up in the middle of the night to use the restroom. This way couples can sleep undisturbed.

Full Size Crib Mattress

Since safety is a top priority for cribs, the size of cribs and mattresses is regulated by the federal government. A full size crib mattress must be at least 27 1/4 inches wide and 51 1/4 inches long. The mattress cannot be more than 6 inches thick.

Room Size

A crib, of course, wont take up much room. But its important to keep in mind most building codes require a bedroom to measure at least 70 square feet, like a 7-by-10-foot room. The ceiling height must also reach 7 feet, 6 inches.

You can certainly create a cozy nursery in an attic room or something comparable to fit a crib and a comfy chair. However, these smaller rooms wont be considered bedrooms when it comes to a real estate listing. No matter what, make sure there is a planned fire escape route if you are squeezing things in tightly.

What Size Is A Twin Mattress

Standard Mattress Sizes Chart

Some people incorrectly think a single bed is smaller than a twin. The terms are actually interchangeable for the same sized mattress. Standard twin mattresses are 39 inches wide. Regular twin mattresses are 74 inches long, and a twin XL mattress is 80 inches long.

Extra-long twin beds are commonly used in college dorm rooms. Theyre ideal for taller people who may not be able to accommodate a wider mattress in their space.

Room Size

A twin size bed, and even a twin XL, can comfortably fit in a 7-by-10-foot room. It can also fit in a smaller room of about 6.5 by 6.5 feet but note this room will not be to code when it comes to real estate. It would also be quite cramped and only be able to fit a small wardrobe and desk.

If you need to fit two single or twin beds in one room, it needs to be at least 9 by 9.5 feet. This minimum size doesnt offer much space between beds. Any added furniture, like desks or wardrobes, would need to be quite small.

If you have it, a 10 by 9.5-foot room or 10 by 10 room would fit two twin beds much more comfortably. Another way to fit two twins in a small space is to consider bunk beds. Kids bunk beds will need at least a 3-foot clearance, and theyre between 4 and 5 feet tall. The minimum ceiling height for kids bunk beds is about 7.5 feet.

For adult bunk beds, youll need a bit more clearance, and they run taller between 5 and 6 feet. Make sure your ceiling is at least 8 feet and 6 inches tall.

This is a great bed if you want the option of inviting pets or kids to join you as well.

Room Size: The recommended room size for a king bed begins at 13 feet by 13 feet up to 13 feet by 19 feet, depending on how much furniture you have and how much walking room you want around the bed.

Other Mattress Size Factors That Influence Your Decision

Buying a mattress is a long-term investment in your health, and there are a number of things to think about during your search for the best mattress. Almost all mattress types are available in all standard sizes, but factors like the size of your bedroom also have to be considered while deciding on the size of your mattress.

How Big Is A Full Size Mattress

What are the Dimensions of a King Size Bed? How long and wide is a King Size Adjustable Bed?

Double mattress dimensions and full mattress dimensions are the same, as the two terms are interchangeable. Full mattresses are 53 inches wide by 75 inches long. You can also get a double XL mattress measuring 53 inches wide by 80 inches long.

Room Size

The minimum room size for a full bed is 9 by 9.5 feet. This wont leave much room for end tables, however. You might consider a headboard with built-in storage or an overhead bookshelf instead.

At 10 by 11 feet, you have a much more comfortable layout. In this case, you can fit wardrobes on the wall and have end tables flanking the bed. When determining your layout, make sure to accommodate clearance for the door to open and close fully.

Olympic Queen Mattress Dimensions

66 inches by 80 inches

Minimum recommended room size: 10 feet by 10 feet

The Olympic queen mattress is six inches wider than the standard queen size and provides enough room for a couple to sleep comfortably, but is not considered to be a standard size. Even when found, its an ordeal to find bedding accessories like sheets to match this size.

The benefit of an Olympic queen size is that it provides a little extra space than the queen size, while not being as big as a king. If your room is not big enough to accommodate a king, but you need more space for sleepers, then this Olympic queen size fits the bill. The Olympic queen size is meant for RVs and camper trailers and are more commonly seen inside mobile homes.

Is King Right For You

On the other hand, we have king-sized beds. These are specifically designed for couples. It goes without saying that it’s not worth it if you are sleeping alone as you could rely on a queen-sized one and use the extra room for something else.

However, if you would be sleeping with your partner, the king-size mattress really shines out. It provides substantial sleeping space for each person so that you don’t have to be tightly close to each other during the hot summer days. On the other hand, it also allows the necessary depth so that your legs won’t be hanging out. This is also something quite substantial.

Full Size Mattress Dimensions: 54 X 75

You may be curious as to why we dont refer to our full size mattress as double beds – a common practice in the mattress industry. While the term double infers that the bed is double the width of a conventional twin bed, it is, in fact, only 15 inches wider. Check out the Puffy Lux Full Size Mattress.

Full bed dimensions are ideal for single sleepers looking for a little more space to stretch out in their bed than what they would be getting on a twin. It is also a viable choice for guest rooms, children/teenagers who do not have enough room for a queen bed, and couples who are ok with 27 inches of width each .

Will A King Size Bed Fit In A 10 X 10 Room

Mattress Size Guide: The Signs, Symptoms and How to Avoid It

Technically speaking, yes. A king mattress is roughly 6 feet by 6 feet, so it will fit in a bedroom that measures 10 feet by 10 feet.

However, we cant recommend this setup since it will leave little room for anything else in your bedroom. You might be able to squeeze in a couple of nightstands with a dresser and still have enough room to walk around, but the room is likely to feel cramped if you do. And a bedroom that feels cramped hardly promotes a relaxing sleep environment.

This is why we only recommend king mattresses for rooms that are at least 12 feet by 12 feet.

Is Twin Xl The Same As Full

Although a twin XL is 15 inches narrower than a full, itâs 5 inches longer. Twin XL beds usually canât comfortably accommodate more than one person, but they are an ideal choice for a single sleeper thatâs too tall for a traditional size bed. Twin XL beds are great for small, narrow bedrooms where thereâs not a lot of floor space, and are often the bed of choice for college dorm rooms and apartments.

What Are Other Considerations To Keep In Mind When Buying A Mattress

Size is an important consideration, but the material of your mattress matters, too. Each type of mattress has different characteristics.

Two of the most popular options on the market are memory foam and hybrid. A memory foam mattress is designed to provide targeted pressure relief by contouring to your body perfectly. On the other hand, a hybrid mattress offers the support of a traditional innerspring and the comfort of memory foam.

The search for a king size bed frame can be overwhelming because the market is flooded with options, and you have to consider factors such as space and budget. The king is the widest among all standard sized mattresses, and the king bed frame may need to be a few inches bigger than your mattress depending on the design.

A king mattress is 76 inches wide, and if you are considering a bed frame with headboards, the total width could add up to 80 inches or more. You need at least 2 inches of space on either side of the bed to fit a headboard.

If you are looking for a king bed, chances are you are upsizing from a queen. While the length of a standard king, also known as an Eastern King, is the same as a queen, its 16 inches wider. The extra width requires much more space than a queen, which is why king beds are best suited for big master bedrooms.

Which Mattress Size Is Right For You

King Size Mattress Sizes

To find the right size of mattress for you, the first thing that you would need to do is to list down your requirement. How many people would use the bed, what is your space requirement, do you like to roll around or do you prefer a cozy space and so on. There is no one-size-fits-all when it comes to mattress purchases, so getting your basic information is important so you can make the right choice.

Another important factor to consider is what are brands giving you in terms of benefits and features. For example, what is the warranty, the trial period, the delivery service etc.

Do Mattress Lengths And Widths Have Anything To Do With Thickness

Length and width are not typically indicators of how thick a mattress will be. Mattress thickness is usually determined by the materials used to make the mattress, and whether it is a pillow top mattress, as the plush top will generally give it a taller profile by a couple of inches. Different mattress constructions can sometimes differ in height – for example, solid memory foam mattresses sometimes aren’t as tall as innerspring mattresses.

Long Single Size Mattress

UK Bed Sizes in Metric. #UK #Bed #Sizes #Metric

You guessed it, its a Single but longer. The Long Single Mattress is the same width as a Single, but the length of a Queen and King. Its primary reason for existence is the Split King, as two Long Singles placed side-by-side are the exact dimensions of a King Mattress.

On some occasions, Long Singles are an option for individuals requiring additional length to a Single but space restricts the choice of the wider King Single.

Look for brands with consistent mattress height across comfort levels when creating a Split King to suit individual partner needs.

Long Singles are ideal for Adjustable Split King Beds and are also popular for couples with different comfort requirements.
