Single bed size (UK)

A UK Single mattress is 90 × 190 cm (900 × 1900 mm), sold as a 3ft bed: 3ft × 6ft 3in. Which?, the National Bed Federation and IKEA UK all agree. A Small Single is 75 × 190 cm (2ft 6in), and a Euro Single, 90 × 200 cm, is 10 cm longer. A US Twin, often called a Single in the US, is wider: 96.5 or 99.1 cm.

What we found

IKEA UK's Small Single is a different bed

Which? and the National Bed Federation give the Small Single as 75 × 190 cm. IKEA UK sells a "Small Single" mattress of 80 × 200 cm for day beds and extendable children's beds: 5 cm wider and 10 cm longer. IKEA's 90 × 200 cm "Junior" mattress has the same size as the Euro Single Which? lists. Fitted sheets for 75 × 190, 80 × 200 and 90 × 200 cm mattresses are not interchangeable.

Published Single bedding widths differ too. Which? lists a Single duvet at 135 × 200 cm; IKEA UK pairs its Single duvet with a 150 × 200 cm cover. A 150 cm-wide cover reaches 30 cm beyond each side of a Single; a 135 cm duvet hangs 22.5 cm over each side.

IKEA UK and Which? were read on 25 September 2026.

Metric size and imperial name: Which? and the NBF buyer's guide, checked 2026-09-24; IKEA UK read on 2026-09-25. In feet and inches, 90 × 190 cm is 2 ft 11⅜ in × 6 ft 2¾ in. The surface is 1.71 m² (18.4 sq ft).

Is a Single long enough? Single vs Euro Single

Which? calls it "the right size for a single adult" unless you are "a lot taller or broader than average". For height, the National Bed Federation advises a bed 10 to 15 cm longer than its tallest sleeper, which on a 190 cm Single means about 175 to 180 cm (5 ft 9 in to 5 ft 11 in).

Which? points anyone whose "feet tend to dangle over the edge of the bed" to the Euro Single, 90 × 200 cm: the same width and 10 cm longer, which raises that limit to about 185 to 190 cm (6 ft 1 in to 6 ft 3 in). IKEA UK sells that size as its "Junior" mattress, and it takes 90 × 200 cm fitted sheets; a Single sheet is 10 cm too short for it.

How much room does a Single bed need?

Approved Document M asks for a 750 mm clear zone on one side of a single bed, and shows a 900 × 1900 mm single bed in its furniture schedule, exactly this size.

Walkway zones: 750 mm, from Approved Document M, Volume 1, paragraph 2.25; the Which? row uses its 2ft 6in (76 cm) instead, from Which?. For this Single with one side open, that is 90 + 75 = 165 cm wide, and the length stays 190 cm because the single-bed rule has no zone at the foot.

For comparison, the government's nationally described space standard sets the smallest single bedroom in a new home at 7.5 m², at least 2.15 m wide. The Single and its walkway zone account for 3.14 m² of that, leaving about 4.4 m² in area terms; whether a wardrobe, drawers and the door swing fit depends on the room's shape.

Small Single size: 75 × 190 cm

A Small Single, also called a narrow single, is 75 × 190 cm, sold as a 2ft 6in × 6ft 3in bed (that imperial name converts to 76.2 × 190.5 cm). It is 15 cm narrower than a Single at the same length. Which? suggests it for a child's room, a box room or a study. Note that IKEA UK's Small Single is 80 × 200 cm.

Do two Singles make a King or a Super King?

Side by side, two Singles make 180 × 190 cm. That is 30 cm wider than a UK King (150 × 200 cm) but 10 cm shorter, and as wide as a Super King (180 × 200 cm) but 10 cm shorter again, so the pair matches neither size. Two Euro Singles, 90 × 200 cm each, do make a Super King; see UK Super King bed size.

A UK Single vs a US Twin and other countries

France sells the same 90 × 190 cm size, as well as the 90 × 200 cm Euro Single. The US Twin is the nearest US size; see Twin bed dimensions. For where the Single sits among the six standard UK sizes, see the full list of UK mattress sizes.
