How Big Is A Full Size Mattress?
A full-size or double bed allows solo sleepers to stretch out or provides enough room for two. Such beds consist of a mattress, box spring and frame, which you typically buy at the same time. You can then later add furnishings such as headboards and footboards as well as side tables and chests.
Size
A full-size mattress measures 53 inches wide by 75 inches long.
Comparison
It is larger than a twin but is the smallest standard size designed for two people. However, it offers less comfort for a couple than two twin beds, which total a width of 76 inches.
Height
Though it can sleep wider-than-average people, a full only fits those who are a maximum of 5 feet 5 inches tall, if you allow for the size of the pillow.
Use
They are popular in children's rooms because the extra width allows room for a parent to read a bedtime story or tuck in a child.
Option
For two people, a far more comfortable option is the queen mattress, which is 7 inches longer and 5 inches wider than the full.
