The guideline we used

A UK super king bed is 180 x 200 cm. A common approach is to lay the rug across the bed, under the lower two-thirds, with about 40 to 60 cm of rug showing on each side, so the rug should be at least 260 cm long, and still leave around 30 cm of floor at the walls.

The table assumes the rug runs the same way as the room. Measurements are for the open floor; subtract fixed furniture such as a fitted unit or chimney breast before you choose.

Layout tips

Keep bedside tables either fully on the rug or fully off it so they do not wobble. If the room is narrow, two runners either side of the bed are an alternative to one large rug. A soft, deeper pile is a good choice in bedrooms where traffic is light.

Frequently asked questions

What size rug for a super king bed in a 3.5 x 4 m bedroom?

For a 3.5 x 4 m room (11 ft 6 in x 13 ft 1 in), the largest standard rug size we stock that follows the usual guidelines is 240 x 340 cm, with 240 x 320 cm or 200 x 300 cm as smaller alternatives.

How much floor should show around a rug?

A common guideline is 30 to 60 cm in living rooms and bedrooms, and less in very small rooms. Narrower borders make a room feel bigger; wider borders frame the rug.

Should I measure the room or the furniture?

Both. Measure the open floor and the furniture the rug needs to sit under, then choose the size that meets both. Marking the outline with masking tape is the easiest check.
