Choosing the right bed size sounds simple until you're actually stood in your bedroom trying to picture it. This guide covers every standard UK bed size, its real dimensions, and what to actually consider before you decide.

Standard UK Bed Sizes at a Glance

Size Dimensions (Width x Length) Best For
Single 90 x 190cm Single sleepers, children's rooms, guest rooms
Small Double (4ft) 120 x 190cm A genuinely UK-specific size
Double 135 x 190cm The most common UK bed size
King Size 150 x 200cm More shoulder room for couples
Super King 180 x 200cm The most spacious standard option

A Genuinely UK-Specific Size: The Small Double

If you've shopped for furniture in the US, the Small Double (4ft) probably won't be familiar — it doesn't really exist as a standard size outside the UK.

Double vs King: The Decision Most People Actually Face

The jump from Double to King is specifically 15cm more width and 10cm more length. We cover this decision in full depth in Double vs King Size Bed.

How to Actually Measure Your Room Before Deciding

Measure your actual bedroom and mark out the real footprint using the dimensions above. Leave at least 60–70cm of clearance on any side you'll regularly walk past.

One Honest Note on Availability

Not every bed style is available in every size — some collections offer the full range, while others focus on Double, King, and Super King specifically.
