Michael Wood II, Purchaser, Retailer and Researcher of Mattresses and Sleep Products. A double and a full size are the same thing. Just different terminology. You'll find that a full size bed - through Google, etc - is 55 Wide x 75 Long. The mattress is usually an inch (or slightly more) smaller in each direction, so; your full mattress will normally measure at (average) 53.5 x 74 - the additional space is to insure that you have room to tuck sheets, etc.
Move on to a full size bed if the bed is 54 inches (137 cm) wide. It should also be 75 inches (191 cm) long. In England and occasionally in the US, this is referred to as a âdoubleâ bed. While a twin bed fits one person, a full bed is best for one large person or two small children or adults.
