UK Double Bed Dimensions

 A UK double bed measures 135cm wide and 190cm long (approximately 53 inches wide and 75 inches long), making it a popular option for its balance between smaller standard sizes (small single, single, or small double) and larger sizes (king and super king). The double bed offers a comfortable compromise between sleeping space and room occupancy, as well as being an affordable option, especially when you find a great deal during mattress sales.

Comparisons to Other UK Bed Sizes

UK Queen/Small Double: Compared to a queen size bed (also known as a small double), which measures 120 x 190cm (approximately 48 x 75 inches), a UK double bed is wider but the same length. A small double is 15cm narrower than a double bed, making it unsuitable for couples but ideal for older children, teenagers, or single adults who need more space.

UK King: On the other hand, a double bed is 15cm narrower and 10cm shorter than a king bed, which measures 150 x 200cm (approximately 60 x 203 inches). Both UK double and king beds are suitable for couples, but a king bed provides more space for sleeping and is better for taller individuals.

UK Super King: A double bed is significantly smaller than a super king bed, which measures 180cm x 200cm (approximately 71 x 79 inches). Super king beds offer the most spacious sleeping area but require more floor space in the bedroom.

UK Single: A single bed in the UK measures 90cm wide and 190cm long (approximately 36 inches wide and 75 inches long). A UK double bed is the same length as a UK single but a third wider. While single mattresses are more suitable for smaller children, doubles are popular for older children, teenagers, and single adults who want more space in bed.

UK Bed Sizes

Bed Size Width (cm / inches) Length (cm / inches)
Small Single 75 / 30 190 / 75
Single 90 / 36 190 / 75

US Double Bed Dimensions

A US double bed, also known as a full-size mattress, is 54 inches wide and 75 inches long (approximately 137cm wide and 191cm long). Essentially, a US double bed is just a few centimetres wider and about a centimetre longer than a UK double bed.

Comparisons to Other US Bed Sizes 

US Queen: The next step up in size from a US double is a US queen, which measures 60 x 80 inches (approximately 152 x 203cm), making it both wider and longer.

 US Twin XL: The next step down is a twin XL, which is 38 inches wide and 80 inches long (approximately 97cm wide and 203cm long). That makes a twin XL narrower by 16 inches but also longer by five inches than a US double bed.

 US Twin: Narrower still, but the same length as a US double bed is a twin size mattress, which is 38 inches wide and 75 inches long (approximately 97cm wide and 191cm long).

US Bed Sizes

Bed Size Width (cm / inches) Length (cm / inches)

Comparisons to Other European Bed Sizes

Euro Single: The Euro single bed measures 90 x 200cm (approximately 35 x 78 inches). This makes it narrower than a Euro double bed but the same length. The Euro single bed is suitable for one person, while the Euro double can accommodate two.
