If you're planning to buy bedding for your current bed and are unsure of the actual size of your bed then our guide on UK bed sizes will help you figure out the size you'll need to buy for. We have put together a quick guide to help you understand the difference in bed sizes. 

Most modern mattresses sold in the UK & Ireland are constructed using imperial measurements but are generally sold in their approximate metric equivalents:

 

Bed/Mattress Size Dimensions (Imperial) Dimensions (Metric)
Small Single / Bunk 2’6” x 6’3” 75 x 190 cm
Single 3’0” x 6’3” 90 x 190 cm
Small Double / 4FT 4’0” x 6’3” 120 x 190 cm
Double 4’6” x 6’3” 135 x 190 cm
King 5’0” x 6’6” 150 x 200 cm
Super King  6’0” x 6’6” 180 x 200 cm

Small Single (2'6'') Bunk

Ideal for younger children or the petite. Small single/ bunk mattresses work well in smaller bedrooms where space is tight. They are also a good ‘transition’ bed for young children moving from a cot into their first bed. You will need to purchase a standard single duvet and duvet cover set when buying a small small/ bunk bed.

 

Single (3'0'')

Suitable for both children and adults, single beds are wider than ‘small singles’ and provide a good amount of room for a single sleeper. This is the most common size for children’s beds, including bunk beds.

 

Small Double (4'0'')

A ‘small double’ (4ft) bed (also known as a Queen or a Three Quarter) is wider than a single bed but smaller in width than a double. It provides plenty of space for one or enough room for two at a squeeze .Great for smaller bedrooms and guestrooms where a standard double won’t quite fit. You will need to purchase a standard double duvet and duvet cover set when buying a small double bed.

 

Standard Double (4'6'') 

A ‘double’ bed (4’6”) is designed to sleep two adults comfortably. This is the most common and widely available size for all bed types in the UK.

 

King Size (5'0'')

A standard ‘King Size’ (5’0”) bed includes a longer length than the standard ‘double’ (6’6” instead of 6’3”).  A king size bed will provide plenty of room for two adult sleepers, but should only be used in larger bedrooms with more space. 

 

Super King Size (6'0'')

The largest of all, the ‘super king’ (6’0”) sized bed provides an abundance of space for two sleeping adults; perfect for couples who prefer their own space!
