Out of all the mattress sizes out there the most popular in the United States right now is the queen sized mattress. That is probably why so many people are asking, “What size is a queen mattress?”, “How wide is a queen mattress?”, and “Is a queen mattress big enough for two people to sleep on?”.

A standard sized queen mattress has an approximate width of 60 inches and length of 79.5 inches, give or take +/- ½” depending on the manufacturer. Mattress heights will vary by product, so please look at the specifications before purchasing.

With the queen sized bed dimensions being approximately 60” wide by 79.5” long, it makes them perfect for single sleepers who toss and turn and roll around alot at night and couples who don’t have the space to accommodate a king size.
