Shop single duvets across lightweight, year-round and winter tog ratings for children’s beds, guest rooms, bunk beds and standard single adult beds. Browse all duvets, or use our UK duvet and duvet cover size guide to confirm the correct measurements before ordering.

Single duvet dimensions

A UK single duvet typically measures 135 x 200 cm. It's cut generously compared with the mattress width, which matters more on a single bed than a larger size — without enough overhang, a single duvet can easily slip off one side during the night, since there's less spare mattress width either side to catch it.

Common uses beyond the main bedroom

Single duvets aren't only for single beds in a main bedroom — they're the standard size for guest rooms, children's rooms, student accommodation, and bunk beds. If you're buying for a child's room specifically, it's worth checking the tog rating suits their room's temperature rather than defaulting to whatever tog is in the main household bed, since children's rooms and adult bedrooms don't always run at the same temperature.

Choosing tog for a single bed

Tog rating works in the same way across every duvet size. Choose according to your bedroom temperature, the season and how warm the sleeper naturally feels:

Single vs. small double — checking you've got the right size

Single and small double beds are sometimes confused when measuring by eye rather than with a tape measure. A UK single bed is 90 cm wide, while a small double runs to 120 cm — a 30 cm difference that makes a real difference to duvet fit if you order the wrong one. If your bed was inherited, bought secondhand, or you're simply not sure, measuring the mattress directly avoids ordering the wrong size.

If your mattress is wider than a standard UK single, compare our double duvets, king size duvets and super king duvets. Measure the mattress before ordering rather than choosing by appearance alone.

FAQ

What size is a single duvet in the UK?
A UK single duvet measures approximately 135 x 200 cm, sized wider than the mattress itself to reduce the chance of it sliding off during the night.
Is a single duvet suitable for a child's bed?
Yes, single is the standard size for most children's beds and bunk beds. It's worth choosing the tog rating based on the room's actual temperature rather than assuming it should match an adult bedroom elsewhere in the house.
How do I know if I need a single or a small double duvet?
Measure the bed width directly rather than guessing — a UK single measures 90 cm wide, while a small double measures 120 cm. That 30 cm difference is enough to leave a single duvet too narrow on a small double bed.
What tog is best for a single bed in a student room or guest room?
10.5 tog is a practical year-round choice for most guest and student rooms, though a lighter 4.5 tog works well if the room tends to run warm, and 13.5 tog suits colder rooms or winter use.
Can a single duvet be used on a bunk bed?
Yes, single is the standard fit for both top and bottom bunks in the UK, since bunk mattresses are almost always single sized.
