Things to Consider Before Deciding Between Twin Size vs Full Size vs Queen Mattress

Room Size

The minimum room size requirement for a twin size mattress is 7 feet by 10 feet. Twin size beds can also be used as a single bed or a bunk bed. 

Both full-size and queen size mattresses are best suited for families or hotels. Both full & queen size mattresses can fit into a room size of 10 by 10 feet and upwards. 


The price range for all three mattresses is influenced by their size, accessories, materials used, and brand. Twin size mattresses are the smallest and least expensive. The full size is priced between $699 – $1700. The queen size being larger than both sizes is priced within a range of $909 to $1800.

So, depending on your budget & requirements you can choose the right one for your room.

Bed Size

The bed size should be the same as the mattress size. In that way, a twin size mattress will require a bed size with a 38 by 75 inches dimension. The full size mattress will sit comfortably on a 54 by 75 inches bed and a queen mattress will have a 60 by 80 feet bed. 

Anything smaller or bigger in dimension will affect the comfort level while sleeping and will also damage the mattress. 


The height of the occupants is a major determinant in this twin full queen feud. With 75 inches in length, a twin size mattress and the full mattress can accommodate people who are shorter than 6 feet. The queen size bed on the other hand accommodates people with height up to 6 feet. 


Accessories for full vs twin vs queen depend on the space each of these mattresses provides. A twin size mattress can accommodate just a pillow and a single-sized duvet suited for a single sleeper.

Both full and queen mattresses can be accessorized with two pillows, a couple of cushions, a small support pillow, and a duvet. The price tag for accessories of each bed size will vary according to the size, material, and brand.
