Twin Bed Dimensions

Atypical single, twin or bunk mattresses are 38” width x 75” length. You’d be hard-pressed to find a bed that is any smaller than this one, other than that of a toddler bed or crib.

Typically this isideal for childrenwho have outgrown cribs and toddler beds, and who are now ready to graduate to a larger mattress.

Additionally, for those who sleep in cramped quarters, who have small rooms or who share a room with a sibling or roommate, Twin beds are an ideal choice. Day beds, bunk beds, dorm room beds or those found in the guest room often use this type.

What is important to note about a Twin bed versus a larger toddler bed, is that comfort is taken more into account. It’s common that, once you reach the Twin size, more quality materials are used, and more engineering centered on comfort takes place. This is because, the older we get, the more we consider comfortable sleeping to be a necessity.

Twin XL

Can I use Twin XL mattress on a King Size Bed Frame?

Yes, you can use two double/twin XL beds in a king frame. If you are in a relationship where one partner requires a different firmness than the other, usually end up being big fans of this setup. This is because Two XL beds can fit snugly alongside each other within a King sized bed frame.

If you are in a relationship, this may not be the best choice for you, as the fit will be exceedingly tight. Likewise, if you have a dog, cat, or you have a child that sleeps next to you, you may want to consider a wider option.

If you have a larger bedroom, then this won’t be a factor for you.

Frequently Asked Questions

Which size is best for me?

Bigger isn’t always better, but in most cases it can’t hurt. More space could mean fewer sleep interruptions, but if you always prefer to cuddle up rather than spread out, that extra space might not be worth it, especially if you’re on a tight budget.

In many cases, couples will opt for a bigger version of a cheap bed, but if you don’t need the extra space, that money could be better spent on features like cooling or motion isolation. For a better understanding of getting your money’s worth, take a look at our mattress budget guide .

  • Second,if you’re moving, don’t forget to measure the room that you’ll be sleeping in. It is awful to have a mattress that is too big for space. You’ll have issues getting around the room, and your space won’t be as aesthetically pleasing.
  • Third,who will be sleeping in it? If it’s just you, you are good to go with a Double. But, if you have a spouse, kids or pets you might want to opt for a larger option such as Queen. King is the ultimate comfort size if your room can accommodate it.

Choosing the Right Size

When shopping for a bed, determining the most suitable mattress size is paramount. Whether it be a king, queen, single, king single or double bed, BedsOnline are sure to have the perfect mattress, with the right dimensions, for you.

The Single

Single beds have dimensions of 92cm x 188cm, and they are great choices for kids of all ages. A single bed will offer your child enough space to comfortably sleep, as well as enjoy their bedroom’s remaining areas. Single beds are also available in a trundle variant, so you can have a single dimension in a bedroom for two kids.

Single beds are a nice option for students who are living alone and are on a tight budget, due to their value and practicality in saving space, especially if you’re sleeping in a small apartment or dorm room where saving space is a priority.

Singles are also good for guest rooms, providing your overnight visitors with a pleasant night’s sleep. Single beds can be a little bit short for some people though, and this is where you should consider getting a king single mattress with its bigger dimensions.

The King Single

A perfect alternative to a single bed, especially if an ordinary single is just too short for you but don’t have the space for a double bed, or anything larger. The king single bed has the dimensions of 106cm x 203cm, and is perfect for people who are taller than the average height. Like a single bed, it’s perfect for kids. Purchasing a king single mattress can provide a parent with the peace of mind that your growing child won’t need a new bed bought in the near future.

Despite being sizeable, the king single might not have ample space for you, and that’s where you need to browse the larger options which are available.

The Double

Double beds have always been that middle ‘sweet spot’ for a lot of people wanting to buy a bed that is spacious, but not too big to be overbearing in their rooms. With dimensions of 137cm x 188cm, double beds are not as lengthy as a king single, but are considerably wider, allowing more movement during your sleep, or even the addition of a partner – two average sized individuals could comfortably sleep in a double bed. If you’re someone who wants a lot of space in sleeping yet can’t afford a queen or king sized bed, or if you simply don’t have the space for one, the double is just the right bed for you.

A double bed could also do the job for your child’s bedroom. If your kid’s room has enough space for a double sized mattress and if it fits into your budget, your child will love their new bed.

The Queen

Probably the most popular size, the queen size beds provide a solid amount of comfort and luxury. The queen’s dimensions are 153cm x 203cm, easily fitting two people. Queen beds are usually for couples that have an average sized bedroom. They provide plenty of space and come in different varieties where the mattresses are specialized to make sure that you don’t disturb your partner when you get up or move around.

If you sleep alone but want the luxury of having that extra space when in bed, a queen mattress is for you.

Whether you are living alone or with your partner, a queen sized bed offers solid bang for your buck.

The King

With dimensions of 183cm x 203cm, king size beds are extremely wide and provide heaps of space for two. King size mattresses are also suitable for couples who value a lot of space when sleeping.

The king size bed maximizes your comfort when sleeping, thanks to the high-end technology found in most mattresses, which makes sure that your movement doesn’t resonate over to your partner’s size of the bed. It may not be the right fit for everyone, but the king sized bed provides the most luxury in space and comfort.

Air mattress size chart & top choices by size

It’s been a while now that I have been receiving questions about the sizes of air mattresses.

How big is a queen size mattress? How big is king size? What is California King? Do the names used to describe size same all over the world or size varies…and so on…

Today, we are putting all those dilemmas to rest in a concise and to the point article which explains it all.

Instead of me talking so much, I’ve decided to make this air mattress size chart that says it all:

Now, let us address the issue if this air mattress size chart applies equally in all parts of the world.

The answer to that is no, not exactly. The differences are minor but they still exist, so let me again try to explain how things stand with a simple size chart for mattress sizes in different parts of the world:

Dimensions of airbeds by country/region:

So, let’s reiterate what we’ve seen about air sizes and dimensions.

Twin airbed dimensions

Dimensions of a twin air mattress are 38 x 74 “, with the height varying from 7 to 25 inches.

Twin XL airbed dimensions

A Twin XL airbed is 38 ” wide, 80″ long and 7-25″ high, depending on the model.

How big is a Full (double) airbed?

Full (or Double) air mattress is 54 inches wide and 74 inches long. The height varies between 7 and 25 inches.

How big is a Full XL airbed?

Full XL is an extra long version of the Full-sized airbed. It’s 54 ” wide and 80 inches long, which is 6 inches longer than a standard full. It can be 7-25 inches high.

Queen size air mattress dimensions

Dimensions of a queen size inflatable mattress are 60 times 80 inches, while the height can be anywhere from 7 to 25 inches.

Dimensions of a King airbed

King air mattress are 76 x 80 inches and can be 6.5-25 inches high.

How big is a California King airbed?

Dimensions of a California King air mattress are 72 x 84 inches and it can be 20-25 inches high, depending on the model.

Again, you can see all these dimensions of inflatable beds converted to metric in the table above as well as our top choices in each size.

I hope that this article clarifies everything about air mattress sizes and eliminates the confusion.

1 – Although California King is available in Canada, this size only represents a small portion of our king mattress sales.

2 – Super king sized mattresses are available from Vispring, makers of hand crafted pocket spring mattresses since 1901. Super king bedding including sheets and duvets are available from St Genève, Canadian luxury specialists.

Nearly all mattress sizes are rounded up. For example a Twin bed in real-world dimensions is usually 38 x 74" or a Double is 53 x 74". Queen and King are almost always 79 inches long. Most mattresses today are still primarily hand made, which will always lead to variances. Foam mattresses tend to adhere to sizing guidelines more accurately than spring mattresses.

Custom Mattresses

Square, rectangle, round, cut corners to fit antique four poster beds, we’re well suited to work with our manufacturing partners to provide these unique requirements. Our hand crafted luxury natural mattress range from Berkeley Ergonomics, Obasan and Vispring allow for just about any possibility.

Our custom mattress category is an excellent starting point for obtaining ideas and approximate pricing on special sized natural mattresses.

Uncommon Mattress Sizes

Our partner suppliers are able to craft a mattress in just about any of these uncommon mattress dimensions. With these sizes it is critical to know that there are two distinct choices available to consumers in Canada:

  1. An inexpensive polyurethane foam mattress cut and upholstered to the sizing required. A mattress made with these materials would usually cost less than $500, regardless of how large. This type of mattress is best sourced from your local foam upholstery shop.
  2. A high quality, hand crafted mattress from our carefully curated range of mattress brands including Berkeley Ergonomics, Obasan and Vispring. Custom sized mattresses made to order start at approximately $1,500.

About Discrepancies

It is not uncommon for a particular mattress to not match up exactly to a size listed above. As many aspects of building a mattress are still done by hand, there will always be variations in sizing from one mattress to the next.

Often times, mattresses may measure as much as one or two inches shorter or narrower than the "official" dimensions. This is considered normal.
