Mattress size guide

Measure your bed frame, find the matching size, and every mattress in that size will fit.

UK and Euro mattress sizes

UK sizes are measured in feet and European ones in centimetres, and the two don't quite line up. A Euro double, for example, is 5 cm wider and 10 cm longer than a UK double.

Every UK size drawn to the same scale. The red outline is a shorty and the blue one is a single.

How to measure your bed

  1. Measure the width

    Measure across the inside of the bed frame, from side rail to side rail.

  2. Measure the length

    Measure from the inside of the head end to the inside of the foot end.

  3. Check the depth

    For bunks, cabin beds, high sleepers and trundles, find the maximum mattress depth marked on the frame.

  4. Match it to a size

    Find the size in the table that matches. If you measure 90, 140 or 160 x 200 cm, you have a Euro frame.
