Futons are a great alternative to traditional mattresses if your bedroom is tiny or if you don’t have one at all. Plus, they work perfectly for guest and living rooms. 

What’s not great, though, is having a headache over choosing the right size of the futon mattress.

Are they equal in size to regular beds or not?

Well, let’s find out!

I’ve made a comparison of the most common futon mattress sizes right below, so you can take a look and find out which one will make a perfect pick for you!

Standard Futon Mattress Sizes

Standard Futon Mattress Sizes

Let’s begin with the standard futon sizes, and I have great news for you here:

Most of the modern best futon mattresses are equal in size to the standard beds.

Typically, they come in four sizes:

  • Twin: 38 x 75 inches;
  • Full: 54 x 75 inches;
  • Queen: 60 x 80 inches;
  • King: 76 x 80 inches.

The sizes with the highest market demand are Full and Queen. They both can accommodate two average adults without eating too much space in the room. Also, most of the futon frames are available in either Full or Queen size, so you can easily pair the frame with the mattress and create a comfy spot for both sleeping and leisure.

You might also find a King-size futon mattress in the line-up of some brands, but it’s rare. King futons are very bulky, so it might be a hassle to flip and rotate them properly. 

Now, let’s find out who can benefit from each futon size the most:

  • Twin. This is the smallest size on the market, which makes it a perfect pick for single sleepers or kids. The smallest also means the lightest, so you can easily take your futon off the frame and use it as a yoga mat on the floor. Just be sure to clean it regularly and aerate to prevent moisture build-up.
  • Full. A Full futon mattress is a good pick for larger single sleepers or an average couple. Also, Full-sized futons are often used as guest beds because they offer decent support and sufficient comfort for occasional sleeping.
  • Queen. A Queen-size futon can be used for both occasional and regular sleeping. It can make a good choice for average couples or heavy sleepers, even taller ones.
  • King. Just like the Queen size, a King-size futon mattress will work for regular sleeping if you or your partner loves to stretch during their shut-eye. Also, you can use it for guest rooms, as it’s large enough to accommodate a heavy couple or an average couple with a small kid.

Non-Standard Futon Mattress Dimensions and Their Characteristics

Along with four conventional sizes, there are a couple of other configurations that you might come across when looking for futons.

These configurations go beyond the standard futon sizes chart, but you still need to know about them in order not to get confused. Or, perhaps you will want to get one of these.

Chair (Lounger)

The tiniest option you can find on the market, they are compatible with — you guessed it — futon chairs. This furniture piece can be used as an alternative to an armchair in your living room, or recline to a lounger that you can use as an occasional sleeping spot. The chair futon typically has a bi-fold design and measures 54 x 28 inches in the unfolded state.

As you can see, this isn’t enough room for sleeping, unless you’re using it for a small kid. However, you can solve the problem by adding an ottoman, which measures 21 inches long and has the same width as the chair. Often, ottomans and chairs are sold together as one set.


Loveseat futon measures 54 x 54 inches and corresponds to a futon frame of the same size. Loveseat futons are commonly used as a sitting spot in a living room or on a veranda. They can accommodate two or three people, which makes them a great choice for those who love friend gatherings.

By adding an ottoman section that measures 54 x 21 inches, you get a sleeping area equal to a Full-size bed.


Split futons consist of a seating section and an ottoman section. This configuration is typically used with futon frames that have a pull-out ottoman section, and here are the dimensions:

  • Twin split: 39 x 54 inch sitting section + 39 x 21 inch ottoman;
  • Queen split: 54 x 60 inch sitting section + 26 x 60 inch ottoman.

So, which futon size will make the best pick for your room, in your opinion? Share your thoughts in the comments!
