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

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.

Now, let’s see who will benefit the most from each size. 

Twin Futon

The Twin futon is the smallest size on the market. Like a regular Twin-sized mattress, it can accommodate a kid or a single adult sleeper. However, futons also feature a different construction, which makes them lighter. So, if you have a Twin-sized futon, its weight easily allows you to take it outdoors for camping, or create another guest space in your kid’s bedroom.

To sum up, you will love a Twin futon bed, if you:

  • need extra sleeping space for your kid’s friends;
  • want a versatile mattress that you can take outdoors;
  • need a guest mattress for small spaces.

Full Futon

Full-sized futons are actually the most common on the market, and every brand you look for will have a Full-sized mattress. Full futons can accommodate two average adult sleepers, or a single overweight sleeper, and can be used as a regular sleeping space. They’re also a bit thicker than Twin-sized futons, so if you need a mattress with a more hugging feel, you might want to check this futon out.

Queen Futon

This is another common futon size. Like a regular Queen-sized bed, this futon can easily accommodate two adult sleepers of all body types. 

 A Queen futon is a great way to organize occasional or regular sleeping space. You can roll it up and store it away when not in use, which is great if you live in an apartment without a separate bedroom and want to keep your space functional.

Queen futons range in firmness and may have a different construction, but the most common design is a mattress tightly padded with cotton or fiberfill. It’s still way lighter than a regular mattress but requires a more thorough airing out to reduce the chances of mold growth.

King Futon

The largest futon size on the market, King, makes a great choice for taller and bigger sleepers. It’s wider than a Queen futon mattress, which gives you extra space to stretch and get comfortable.

Note that, unlike regular King mattresses, which are pretty standard, King futons aren’t that easy to find, and not all major brands offer them. Plus, finding one will probably cost more than more common futon sizes if you manage to find one.

Non-Standard Futon Mattress Dimensions and Their Characteristics

Non-standard futon mattress sizes

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.
