Double duvet dimensions

A UK double duvet typically measures 200 x 200 cm. It's one of the most commonly bought sizes in the UK, which also makes it one of the easiest to get wrong when shopping online, since "double" bedding is sometimes used loosely to describe small double or even king products by less careful retailers. Checking the exact cm measurement against your own mattress is the safest way to confirm fit.

Double vs. small double — a common mix-up

A standard UK double bed measures 137 cm wide, while a small double measures 120 cm — a 17 cm difference that's easy to misjudge by eye, particularly in older UK properties where small doubles are common due to room size. If you're replacing a duvet on an existing bed rather than buying alongside a new one, it's worth measuring the mattress directly rather than assuming based on how the bed has always been described.

If your mattress is not a standard UK double, compare our single duvets, king size duvets and super king duvets. Measure the mattress directly before ordering, particularly when deciding between a small double and standard double bed.

Choosing a tog rating for a double bed

The same seasonal logic applies regardless of bed size, although two people sharing a double bed should also consider their individual warmth preferences:

Sharing a double bed with different warmth preferences

A double bed offers less individual space than a king or super king, which can make mismatched temperature preferences between two people more noticeable. Since a double bed is narrower, splitting to two single duvets isn't always practical the way it can be on a larger bed — so it's often more a case of settling on a tog rating that's a reasonable middle ground for both people, or adding a throw for whoever runs colder.

FAQ

What is the exact size of a UK double duvet?
A UK double duvet measures approximately 200 x 200 cm, sized to overhang a standard double mattress on both sides.
What's the difference between a double and small double duvet?
A double bed is 137 cm wide compared with 120 cm for a small double — a 17 cm difference. Measuring your mattress directly is the most reliable way to tell the two apart if you're unsure.
Is 10.5 tog enough for a double bed all year round?
For many centrally heated UK homes, yes, though colder bedrooms or anyone who feels the cold more may prefer stepping up to 13.5 tog in winter and down to 4.5 tog in summer.
What tog rating works best if two people share a double bed but run different temperatures?
A middle-ground tog, such as 10.5, is often the practical compromise on a double bed, since it's narrower than a king or super king and less suited to splitting into two separate single duvets.
Does a double duvet fit a small double bed?
It can work, though it will hang slightly further over the edges than intended. For the neatest fit, matching the duvet size to your exact bed width is the better option where possible.
