If you’re new to the mattress industry, and have just recently started searching for a new bed, you’re likely to soon encounter the topic of mattress sizes.
While it might seem like a no-brainer at first, I bet you a cookie (I didn’t say that) that it’s a more complex and time-requiring topic than you might think. That is why today, in this “All About Mattress Sizes” article, we’ll talk about everything from crib mattress sizes all the way to full size bed dimensions.
At first, I’ll tell you why it’s important to invest some time into the topic of mattress sizes. After that, we’ll move on to talking about the actual sizes themselves, and see if we’ll be able to find the perfectly-sized bed for you.
Why are Mattress Sizes Important?
Usually, when people are looking for a brand new bed, they (more or less) have an idea of what size that bed should be. After all, there’s a pretty big difference from a crib mattress size and a twin mattress size, right?
While that may be true at first glance, the fact of the matter is that most of the time, people give the sizing of their future mattresses very little attention.
That should not be the case!
You see, I would argue that the dimensions of your bed are going to be one of the more important things for you to figure out. There are a lot of different factors that come into play here, but let’s begin from the most obvious one - space.
There are two groups of people when it comes to the available space for a new mattress in their bedroom - the “an inch here, an inch there and it will fit” ones, and their “we live in an empty void, but we should still go with the twin mattress size, just in case” counterparts.
Space management is important, and will directly correlate with the different mattress sizes. That said, there’s an even more important factor that plays a role as far as numbers are concerned - price.
The general rule is that the bigger the mattress, the more it’s going to cost. While you can sometimes look up a full size bed dimensions and just go with it, it’s often better to save up an extra few hundreds of dollars and start looking at queen size bed dimensions.
With that out of the way, let’s take a look at the sizes themselves - we’ll talk about some other reasons for while choosing appropriate mattress sizes is important as we progress through the article.
Crib Size Mattress
The smallest mattress out there, crib beds are made for a single purpose - children. Babies, to be more exact - there are quite a few decent crib mattress providers out there that are adamant on helping you choose the best bed for your kid.
A standard crib mattress size is going to be around 71 cm X 132 cm, or 27” X 52”. While they might differ slightly from provider to provider, cribs beds should al range around these measurements.
Twin Size Mattress
The default twin mattress size is going to be 96,5 cm X 190,5 cm, or 39” X 75”. This type of a mattress is very popular among teenagers and young adults who live alone.
Now, that being said, it’s worth mentioning the mattress is still tiny - as in, really tiny. An adult will fit on it, but it’s not going to be too comfortable.
Twin mattresses are pretty good if you tend to travel quite a bit, and don’t really want to carry an air mattress around with you. While it might not be too comfortable, some people do prefer to take their twin beds with them on longer journeys, especially if they are of some specific quality.
An alternative to that, however, are twin XL mattresses - these are 96,5 cm X 203,5 cm, or 39” X 80” in size. Twin XLs are designed for taller people, and they don’t tend to cost much more than the original versions.
Full Size Mattress
Full size bed dimensions are 134,5 cm X 190,5 cm, or 54” X 75”. A full size mattress is of the same height as a regular twin one, it’s just a bit wider.
Now, with a full-sized bed, you have two options - you can either sleep really comfortably yourself, or you can kind of squeeze two people on it. Generally, a bed of this size is not recommended for couples - there are a few exceptions, though.
First of all, if you’re struggling to make ends meet, but you still want a great bed to sleep on, then a full size mattress might be the best option to go for. Queen and king size bed dimensions would probably suit you more, but these mattresses tend to be quite a bit more expensive.
The full size mattress is also a decent choice if you’re living a bachelor’s life. It’s a great bed to sleep alone, and you don’t need to worry about spending too much money on bigger mattress sizes in the situation suddenly changes.
Queen Size Mattress
Now, we’ve reached the most popular mattress type out there - the queen mattress.
The Queen size bed dimensions are 152,5 cm X 203,5 cm, or 60” X 80”. As I’ve already mentioned, out of all the mattress sizes, the queen bed has to be the most popular one. Some people might come to think that the king or the California king bed dimensions are more suitable for anyone who wants to sleep like, well… a king.
Nope. Apparently, the queen mattress is usually the perfect combination of length and width.
Queen size bed dimensions are suitable for almost anyone - single people love them, couples love them, everyone loves ‘em! This is also the mattress type that can reveal the full potential of the brand to the customer - let me explain.
Creating a, say, responsive twin mattress isn’t going to be really difficult, since it’s a pretty small product. However, if a company like Saatva manages to make their queen-sized beds bouncy, maintain great edge support and longevity - now that’s impressive!
King Size Mattress
King-sized mattresses usually come in two different versions:
- King size bed dimensions - 193 cm X 203,5 cm, or 76” X 80”;
- California king bed dimensions - 183 cm X 213,5 cm, or 72” X 84”.
The normal king size bed dimensions will suit anyone who sleeps with a partner, but also likes their privacy. Honestly, when compared to the other mattress sizes, the king bed is huge - if you and your significant other sleep on the opposite sides of the mattress, you might not even feel that there’s another person on the bed!
As for the California king bed dimensions, these are specifically designed for people who live in California.
Yup. If you live anywhere else in the world, you are FORBIDDEN to purchase this mattress.
Nah, I’m just joking… Or am I?
OK, on a serious note, though, Cal king is made for anyone who tends to experience the problem of their legs hanging out of the king-sized mattress as they sleep - in other words, for tall people.
How to Choose the Right Mattress for Yourself?
So - there you have it! By now, we’ve discussed all of the major mattresses sizes that there are. Some companies do have some additional sizing options, and you could always order a custom bed, but these are exceptions - as for the default ones, we’re all done.
Now that you know all about the main mattress sizes, there’s only one question left to answer…
How do you choose the appropriate mattress size for yourself?
Well, there are a few different factors that you should always keep in mind.
Alone VS With Partner
Naturally, when deciding on the different mattress sizes, the very first thing that you’ll want to do is figure out whether you are going to be sleeping alone or with a partner.
While some people might immediately say “alone!”, I do advise you to think about it. While you might be alone right now, who knows what tomorrow will bring? After all, a good mattress might serve you for a decade and beyond!
Pricing is a very normal factor to consider when thinking about mattresses sizes.
As I’ve mentioned earlier, different sizes come in different prices. Some mattress providers have rather small gaps in price tag between their products, while others might give you a heart attack.
The general rule of thumb is simple, though - if you can wait and save up some more money to buy a bigger mattress, that’s exactly what you should do. While it might not be possible in some situations, people usually opt to go with the bigger products.
In the grand scheme of things, however, that does make sense. Bigger mattress sizes, while being a bit of a heftier investment, are a more logical way to go about purchasing a new bed than smaller ones. They are likely to serve the customer longer, be more comfortable and so on.
Quality of Build
Finally, while this might not always be applicable to some of the top mattress providers out there, you should always consider the quality of the mattress.
But doesn’t a company create its products of equal quality?
Well, that’s tricky. Sure, most companies really do put in the same amount of effort into their beds, whether twin or king-sized ones. That being said, this goes back to the above-talked-about point of bigger mattresses often being better long-term choices.
The simplest way you could think about it is this: if you were to sleep on a twin-sized mattress, you wouldn’t really have much space to choose from. This means that the same exact area would be constantly experiencing the same amount of pressure. As opposed to that, on a queen or king mattress, you could roll around without much problem.
This and a few other similar details tend to stack up over time - after all, you’re probably going to have that mattress for more than a year or two. This doesn’t only impact the product’s longevity, but also the strength of its edges, responsiveness, etc.
To sum it all up, the deal is pretty simple - while there are specific situations where a smaller mattress is the better choice, as far as mattress sizes are concerned, you should always strive to go with the bigger option.
Bigger mattresses will be better for your sleep, they will last longer and will also provide you with the option of sleeping with your significant other (whether now or in the future).
Some good examples of bigger mattresses are Saatva, the New Purple (or even their flagship product), Nectar and Puffy. While these providers do have all-around amazing products, their bigger beds are what people value the most.
This concludes our “All About Mattress Sizes” tutorial. In it, you should have not only found out about the dimensions of the different mattresses sizes, but also some tips and tricks to help you better understand which size would be the most appropriate for you.
Also, keep in mind the fact that most mattress providers (at least good ones) have sleeping trials - periods of time during which you can test their product out, and if you don’t like it, turn it back in and receive a full refund.
All in all, if you do know what mattress size suits you best, but you’re still not sure about the brand, do take a look at our list of the best mattresses of the year. Who knows - maybe you’ll find one that will suit you?
