One of the most important factors to consider when choosing an air mattress is the size. With several size options and dimensions available, your choice should depend on how much space you have and how many people will be using the mattress. So, what are the dimensions of a full-size air mattress?
A standard full-size air mattress typically measures 75″ x 54″ x 18″, though the width may vary slightly depending on the brand. These dimensions closely match those of a regular full-size mattress, which makes choosing the right fit much easier. If you need more space, a king-size air mattress will offer significantly larger dimensions.
In this article, we’ll take a closer look at full-size air mattress dimensions and how they compare to other common sizes, including queen and king air mattresses.
Full-Size Air Mattress Dimensions
The exact dimensions of a full-size air mattress will vary depending on the company you buy it from, but they’re generally in the same range.
Below, I’ll talk about two different full-size mattresses (available on Amazon.com) and their corresponding dimensions:
- YENING Full Size Air Mattress. The dimensions of this full-size air mattress are 75″ x 54″ x 18″ (190 x 137 x 46 cm). Plus, it has a capacity of 600lbs (270 kg), so it’s perfect for more than one person.
- SoundAsleep Dream Series Air Mattress. The SoundAsleep air mattress is slightly bigger than the above, with dimensions of 76″ x 56″ x 18″ (193 x 142 x 46 cm). So if you’re looking for a bigger full-size air mattress, this would be a good choice. You can inflate this mattress in under four minutes, so it’s highly convenient.
Will a Full-Size Air Mattress Fit Two People?
A full-size air mattress will fit two people in most cases. Since the general width is between 54″ and 56″ (137 and 142 cm), two normal-sized people can lie somewhat comfortably on a full-size air mattress. However, if both people are overweight or obese, it’s good to check the weight capacity in case it can’t hold the weight.
Furthermore, both adults should be comfortable sleeping close together if they will be sleeping on a full-size air mattress because there won’t be a lot of extra space.
The Height of a Full-Size Air Mattress May Vary
While the width and length are generally the same/almost the same in all full-size air mattresses, the height can vary. Both of the air mattresses I mentioned above have heights of 18″ (46 cm), so they’re relatively tall. However, you might find mattresses much shorter than this.
Shopping around will give you a better idea of the different height options. If you’ve realized the dimensions of a full-size air mattress are too small, you might want to consider a queen or king one instead.
Queen-Size Air Mattress Dimensions
Although full-size mattresses can fit two normal-sized adults, they’re better for one person because of their smaller width. This goes for air and standard mattresses.
A queen-size air mattress is slightly bigger than a full-size one, so you may decide to go with one of these instead. The general dimensions of a queen-size air mattress are 80″ x 60″ x 20″ (203 x 152 x 51 cm), but these figures may vary slightly depending on the specific mattress.
An example of a queen-size air mattress with the above dimensions is the King Koil Luxury Air Mattress, available on Amazon.com. It’s a standard queen size, perfect for two adults (or one adult if you want lots of space)!
Like with full-size air mattresses, the height of queen mattresses can also vary. While the one mentioned above has a height of 20″ (51 cm), you can likely find ones shorter than this.
King-Size Air Mattress Dimensions
A king-size air mattress is bigger than a full-size one, so you should consider one if you have enough space and want two adults to sleep comfortably. The standard dimensions for king air mattresses are approximately 80″ x 72″ x 18″ (203 x 183 x 46 cm).
You can find king air mattresses on Amazon.com, including this Intex Comfort Dura-Beam Airbed 2020. This air mattress is perfect for one or two people and comes in different heights, so you’re spoiled for choice.
Twin Air Mattress Dimensions
A twin air mattress is the smallest one you can get, perfect for one person and smaller spaces. You can expect the dimensions of a standard twin air mattress to be approximately
75″ x 39″ x 16.5″ (191 x 99 x 42 cm).
An example of a twin air mattress with these dimensions is the Intex Dura-Beam Pillow Rest Air Mattress, available on Amazon.com. The weight capacity of this mattress is 300 lbs (136 kg), and it’s perfect for one adult or child.
To compare the dimensions of different air mattresses, check out the table below:
| Type | Width | Length |
| Full-size | 54”-56” (137-142 cm) | 75”-76” (191-193 cm) |
| Queen | 60” (152 cm) | 80” (203 cm) |
| King | 72” (183 cm) | 80” (203 cm) |
| Twin | 39” (99 cm) | 75” (191 cm) |
Conclusion
A full-size air mattress is more compact than a queen and can fit one or two adults. The dimensions are approximately 75 ” x 54 ” x 18″, but these measurements can vary slightly.
If these dimensions are too small, you should consider a queen or king air mattress. If you realize a full-size air mattress is too big, it might be best to stick with a twin mattress.
