Tog is simply a measure of how warm a duvet is. The higher the number, the warmer it keeps you. Picking the right one makes a big difference to how well you sleep, so here's a quick guide.
Tog ratings at a glance
- 4.5 tog – light and cool. Ideal for summer, warm bedrooms or anyone who runs hot at night.
- 10.5 tog – the all-rounder for spring and autumn, or for a well-heated home all year.
- 13 tog – a cosy winter weight that suits most British bedrooms from October to March.
- 15 tog – our warmest. Perfect for cold rooms, older houses or anyone who always feels the chill.
What tog duvet for winter in the UK?
For most people a 13 tog duvet is the sweet spot for winter. If your bedroom is cold or you turn the heating off at night, go for 15 tog.
What tog for summer?
A 4.5 tog duvet keeps you covered without overheating on warm nights.
Should I choose one duvet for the whole year?
If you'd rather not swap, a 10.5 tog works for many homes. Some people keep a 4.5 tog for summer and a 13 or 15 tog for winter, which gives the best of both.
Other things to think about
- Sharing a bed? Two people create more heat, so you may want a slightly lower tog than if you sleep alone.
- Allergies? Hollowfibre duvets are a good feather-free choice and can be washed.
- Size: a duvet a size bigger than your bed stops the tug of war on a shared bed.
