One source gives the Full a different length
The published guides don't agree on the length of a Full, so check the product dimensions before you buy:
- Sleep Foundation twin size guide: 54 × 74 in.
- Sleep Foundation double-bed guide and Target: 54 × 75 in.
- Queen's extra length: 6 inches with the 74-inch Full, rather than 5 inches.

Common questions
How much bigger is a Queen than a Full?
A Queen is 6 inches wider and 5 inches longer, about 18.5% more sleeping surface. Use the width and length rows to check room fit, or the Area row to compare surfaces.
Is a Full bed big enough for two people?
Check the per-person row to see how much width you'll have when sharing; a Full gives each sleeper less width than a single Twin mattress. Since measurements can't tell you whether a bed feels comfortable, compare them with the space you and your partner use now.
- Single Twin for comparison: 38 or 39 inches wide, depending on the source.
Is a Full as big as a Queen?
No. A Full is 6 inches narrower and 5 inches shorter than a Queen.
Is a Queen worth it over a Full?
If a Full leaves you short of sleeping space, compare the extra width and length with what your room can hold. Our Queen measurements and room-size guide works out the floor space a Queen needs with walkways. Measure your frame too, since the mattress dimensions don't include what the frame adds. Check bed frame dimensions for measured examples before you buy.
- Full mattress length: 75 inches, or 6 feet 3 inches.
- Queen mattress length: 80 inches, or 6 feet 8 inches.
- IKEA MALM Queen frame footprint: 66⅛ × 83⅛ in.
Full, Double and the UK Double
In the US, Full and Double mean the same size, which Sleep Foundation calls "full/double".
- UK Double imperial name: 4ft 6in × 6ft 3in, the same 54 × 75 in.
- UK Double metric label: 135 × 190 cm, or 53.1 × 74.8 in.
If you're buying bedding labelled "double", check its measurements and which market it's made for. See UK vs US bed sizes. Parachute sells one Full/Queen duvet insert for both beds, so it hangs further over a Full; see how a Full/Queen duvet fits each bed.
