BED SIZES GUIDE

Looking for mattress sizes? This article will help you find the right sizes and dimensions for your mattress. Beds come in many sizes, from the small single Twin, queen-size, and go all the way to the massive California King. Unfortunately, manufacturing procedures, padding, and types of support can all alter the size.

IMPORTANT: This guide offers the most common sizes. It is important to know that there are no legal standard mattress dimensions. As a result, if you are looking for a specific bed size in Canada or the USA, be sure to ask your vendor for exact measurements if you are unclear.

In Canada and the USA, we use terms like Queen, King, Double, and so on to define mattress sizes. In other places, like various European countries, the language can be different, and the same name could apply to a quite different size. So be on the lookout if your set isn’t from North America!

The sizes between coil and foam mattresses vary a bit, but there’s a particularly good reason! Innerspring coil mattresses are much harder and don’t squish around as foam mattresses do. As a result, and to make it easier to fit into frames and tuck sheets under them, they’re often just a touch smaller. This difference won’t be noticeable in your bed frame, so don’t worry!

The stiffer nature of the innerspring coil does have to be accounted for, but the manufacturers do that for you.

All these sizes have different intended purposes, and below we’ve listed those for you! Whether your baby is growing up and you want to get them a real bed to sleep in, or the old double you sleep on isn’t good enough for two people anymore, there are options for everyone.

(39″ × 75″)


Despite ‘Twin’ being in the name, twin-sized mattresses are intended to be used by one person.

This makes it the perfect size mattress for a young child who has grown past the need for a toddler mattress. Twin mattresses are also great for those in adolescence or single adults. Due to its smaller size width and length, it is common in dorm rooms and spaces where more than one mattress is in place. Twin mattress dimensions are smaller and more affordable than larger mattresses.

Their small size means they’ll fit well in most spaces. It’s an immense size for growing kids to give them enough space to sleep and grow without taking up so much space in their room. It’s also the most common bed measurement found in dorms due to their compact but comfortable size, though it’s a bit short for some college students. Because of that, a lot have switched to the Twin XL.

HOW LONG IS A TWIN BED?

The average length of a single bed is 75 inches.

HOW WIDE IS A TWIN BED?

The average width of the single bed is 39″.

As a twin, the mattress is the same width but is 5 inches longer to accommodate taller sleepers. This size is commonly used for growing teenagers who are close to 6’0” and in dorm rooms where there are more athletes.

  • This size mattress only fits one full size adult in most cases.

 

Super Single Bed Size Mattress Dimensions

SUPER SINGLE BED SIZE / THREE-QUARTERS (3/4) BED SIZE

(48″ × 75″)


Super Single beds are a throwback to the 1920s. Designed for one sleeper but often accommodating two, these beds are exceedingly rare on the market today. Only antique bed frames and military living quarters will require this size, so Gotta Sleep doesn’t carry it. You’ll like to have to find a custom or specialty mattress store to get a mattress this size that is both comfortable and new.

Super Single bed dimensions measure 48″ × 75″. The average width of a single bed is typically 48″. The average length of a single bed is 75″.

(54″ × 75″)


The double, or the full, used to be the industry standard for a bed meant for two people. It wasn’t until the 1950’s that the Queen-sized mattress overtook the market, as ad campaigns didn’t want to depict couples getting too close, and the space was quite appealing.

How wide is a Double Bed Size? 54″. How Long? 75″.

The full-size bed size and dimensions are perfect for pre-teens and children. This size fits one individual with a height of less than 65 inches. The Full or Double mattress is 17 inches wider than a Twin mattress.

It’s a popular choice nowadays for spare bedrooms, luxurious singles, growing children, or rooms that would just be overtaken by a bigger mattress size.

Full mattresses work great for children as they are cost-effective and are long enough to last until the child has grown into an adult and can buy their mattress for their needs.

Full-size box spring dimensions differ based on the model so be sure to check your vendor’s specifications if you’re worried about it.

Double mattress measurements or full-size bed dimensions typically measure 54″ × 75″. The average length of a double bed can extend to 75″ depending on the manufacturer. The width of a double or full bed is 54″.

Queen beds provide plenty of space for sleeping, even for those who move a lot in their sleep. This makes it even more desirable for couples, as getting up or rolling over won’t disrupt the other person’s sleep.

Queen mattresses have more room than the rest of the list so far, so restless sleepers can sleep through the night without being bothered every time the person next to them turns in their sleep. Sure, bigger mattresses do this too, but bigger is not always so much better.

Because it’s the most popular size on the market, it’s where the market is most competitive. That’s good news for buyers because you’ll be able to find a better deal with significantly less work on your part.

XL or California King mattresses can be ideal as since they provide more length to accommodate longer legs. Or you just need more height to your bed because you have a dog that likes to sleep by your feet. Whatever your reasons, you should figure out how much room you’re going to need.

When you are unable to comfortably fit your entire body on your mattress, you are potentially compromising your quality of sleep. With the wide variety of dimensions available, no one should have to sacrifice comfort because of their above-average height. Except for certain NBA players but I’m sure they can afford custom mattresses if they need to.

 


 

ROOM SIZE

The size of the bedroom or space where you would like to place the mattress is another factor to consider when choosing the perfect mattress. A mattress too small or too large can offset the feel of the bedroom and leave it feeling either empty or overloaded. If space is limited a smaller mattress is always recommended, but you do have to keep your other needs in mind. A smaller mattress might be a worthy sacrifice for your dresser set, but you might be better off with less space if you and your partner will push each other off a double-sized mattress.

 

Before making a purchase, it’s important to measure the room to figure out how much space you must work with. It helps to set up your bed frame if you already have one before you go shopping because you’ll know exactly what you’re working with. You want to make sure the room has enough space to safely navigate through, and enough space for other furniture like an end table and/or dresser. Of course, if the room can accommodate a larger mattress, having more space is worth it. Who doesn’t want to feel like royalty?

 


 

CONSIDER THE HEIGHT

As mentioned before, the height of the mattress can make or break how useful it is to you. If your bed frame and box-spring are high off the ground, thick mattresses aren’t going to serve you very well. Tall beds are harder to get in to, but short beds are harder to get out of.

You must consider all parts of sleeping while figuring out what your sleeping situation is going to look like. You don’t want to throw out your back every time you stand up, and you don’t want to roll onto your bed every day just because you can’t lift your leg. Your mobility affects everything, and it should be accounted for.

 


 

NUMBER OF SLEEPERS

For individual sleepers, a Twin or Double-size mattress will provide a good amount of room to make sure a quality sleep. If you share a mattress the bigger you can afford the better. For two people a Queen or King-sized mattresses are ideal.

If you’re lacking space, a double-sized mattress is the next best option. It did use to be the standard; it was made for two people at one point. We’re just a bit more spoiled than we used to be and for good reason!

When sharing a mattress with two adults and children or pets a King or California King-sized mattress is considered the best. These large mattresses will provide space for two or more people to sleep comfortably.

Putting a big mattress in a too-small bedroom can be a safety hazard and make the room feel cramped and uncomfortable, but sometimes it’s worth the extra comfort to fill the room. Bedrooms aren’t meant for much other than sleeping anyways! Just watch for fire hazards!
