Basically, air mattresses are available in 4 different sizes and dimensions. One is meant for only one person, and others are made for two or more people. The commonly used sizes are Twin, Full, Queen, and King size.

Now, let’s have a look at the dimensions and needs of the particular mattress.

One thing to keep in mind before going ahead, that airbeds usually come in two different heights. One is single-height, and the other is double-height.

The height can range anywhere between 4–5 inches to 20–21 inches. So, in this guide, we will only be focusing on their length and breadth.


Twin size is the starting size of an airbed. Only one person can use these air mattresses at a time. These are slightly inexpensive, lightweight, and much convenient to transport than other air mattresses.

Usually, these mattresses have a length of around 74–75 inches and a breadth around 38–39 inches.

A slightly bigger version is also available of twin-sized blow-up beds called Twin-XL that measures almost the same in breadth but has a bit longer length, which is nearly 79–80 inches.

Twin XL Mattress: l x b — 80 X 38 Inches


Full-size air mattresses can be used for up to 2 people simultaneously. These are mostly used on outdoor trips and vacations. If we talk about its dimensions, it has around 53 to 55 inches of breadth and 74 or 75 inches of length.

Full Size Mattress: l x b — 74 X 54 Inches

It also comes with its bigger version, which fits best for tall people. It has the same breadth as a full-size airbed but has a little more length than them, because of which they are also called Full XL.

Queen-sized air mattresses are suitable for resting or sleeping for three people at the same time as they have enough weight lifting capacity to carry you and your two friends or family members of average weight.

These are expensive than the twin size and full-sized beds but offer a great value. Coming to their dimensions, they are around 60–62 inches wide and 80 inches long.

King-sized air mattresses are the largest beds on which 2–3 people of any weight category can sleep easily. However, these are somewhat expensive, relatively heavier, and require more time to inflate than other airbeds.

An average king-size bed has a length of around 76 inches and a width of approximately 80 inches.
