Mattress size chart

See the common bed sizes of each region side by side, in centimetres or inches. The same name can mean a different size in another country, and makers vary by a few centimetres, so check the exact size before you buy sheets or a frame.

Worked example

A US Queen is 60 × 80 in, which is 60 × 2.54 = 152.4 cm by 80 × 2.54 = 203.2 cm. The Australian Queen, 153 × 203 cm, is almost the same bed.

Tips

Measure your bedroom and leave room to walk around the bed.
Check the sheets: a UK double fitted sheet will not fit a US full without stretching.
Add the mattress thickness for fitted sheets; deep mattresses need deep-pocket sheets.

Frequently asked questions

What are the standard US mattress sizes?

Twin 38 × 75 in, Twin XL 38 × 80 in, Full 54 × 75 in, Queen 60 × 80 in, King 76 × 80 in and California King 72 × 84 in. In centimetres that is, for example, Queen 152.4 × 203.2 cm.

Is a UK king the same as a US king?

No. A UK king is 150 × 200 cm (about 59 × 79 in), narrower than a US king at 76 × 80 in (193 × 203 cm). The UK super king, 180 × 200 cm, is closer to the US king.

Why do European sizes differ from the UK and US?

Europe mostly uses widths in round centimetres (90, 140, 160, 180, 200) with a 200 cm length, while the UK and US use older foot-and-inch based sizes. Exact sizes depend on the country and the maker.

Do mattress sizes vary between brands?

Yes. Nominal sizes are a guide; many makers differ by a centimetre or two, and some countries use extra sizes. Check the exact size of the mattress and the frame before buying.
