Queen-size mattress (US) Size Guide

A US queen mattress is 60 x 80 inches, or 152 x 203 cm (1524 x 2032 mm). It is the most popular mattress size in North America, wide enough for two adults but small enough to fit a modest bedroom.

This guide covers the exact queen dimensions, how they compare to a king and a full, how much floor space the bed needs with walkways, and how much a queen mattress weighs.

Quick Answer: How Big Is a Queen Mattress?

A standard queen is 1524 mm wide and 2032 mm long (60 x 80 in, 5 ft x 6 ft 8 in). Mattress thickness is usually 250 – 350 mm. A queen mattress weighs roughly 20 – 45 kg depending on type (foam is lighter, innerspring and hybrid heavier).

6 Everyday Comparisons for a Queen Mattress

1. A king mattress (1930 x 2032 mm) is 406 mm (16 in) wider but the same length.
2. A full/double mattress (1372 x 1905 mm) is 152 mm (6 in) narrower and 127 mm (5 in) shorter.
3. A twin mattress (965 x 1905 mm) is 559 mm narrower and 127 mm shorter, about 63% of a queen’s area.
4. A standard interior door (813 x 2032 mm) is exactly as long as the mattress and about half its width.
5. A 3-seat sofa (about 2000 mm wide) is roughly the queen’s length laid on its side.
6. Two A0 sheets (841 x 1189 mm each) laid together roughly match a queen’s footprint.

Queen Mattress Size in Different Units

How Much Room Does a Queen Bed Need?

The mattress alone is 1.52 x 2.03 m, but the bed frame adds 50 – 150 mm on each side, and you want at least 600 mm (2 ft) of walkway on the sides and foot you use. That puts the practical minimum bedroom at about 3.0 x 3.4 m. A 3.0 x 3.0 m room fits a queen but feels tight; 3.7 x 3.7 m is comfortable with bedside tables and a dresser.

How Much Does a Queen Mattress Weigh?

A queen is usually a two-person lift, especially through doorways and up stairs, because the 2032 mm length is longer than most hallways are wide.

Common Mistakes When Comparing Queen Mattress Dimensions

1. Assuming a queen and a king are the same length. Both are 80 in long; only the width differs (by 16 in).
2. Confusing “queen” across countries. A UK king is about 150 x 200 cm, close to a US queen but not identical.
3. Forgetting frame overhang. The bed frame and headboard add 50 – 200 mm beyond the mattress.
4. Ignoring mattress height. A tall hybrid plus a box spring can put the sleep surface 700 mm off the floor.
5. Planning a room to the mattress, not the walkways. You need 600 mm of clearance to make the bed and get in and out.
