A duvet tog guide matches a duvet's warmth rating to the time of year. In the UK, up to 4.5 tog suits summer, 7.5 to 10.5 tog suits spring, autumn and most of the year, and 13.5 to 15 tog suits winter and cold bedrooms. Your bedroom's temperature matters as much as the season, so use the chart as a starting point.
| Season | Tog | Notes |
|---|---|---|
| Summer heatwave | 1 or 2.5 tog | Little more than a cover |
| Summer | 4.5 tog | The standard summer weight |
| Spring and autumn | 7.5 tog | Light, for mild nights |
| Most of the year | 10.5 tog | The all-season middle weight |
| Winter | 13.5 tog | For rooms that cool at night |
| Cold winter rooms | 15 tog | The warmest standard rating |
If tog itself is new to you, our guide on what a tog rating means explains how it's measured.
Is a 10.5 tog duvet warm enough for winter?
Yes, a 10.5 tog duvet is warm enough for winter if your bedroom is heated. In a room where the heating goes off overnight, or in an older, draughty house, 10.5 tog will feel thin by January and a 13.5 tog is the better choice.
Our page on the 10.5 tog duvet goes through when it works year round, and our winter duvet tog guide compares 10.5, 13.5 and 15 tog for cold months.
Is a 7.5 tog duvet too warm for summer?
Yes, a 7.5 tog duvet is too warm for most people in a UK summer. It's a spring and autumn weight. On warm nights, 4.5 tog is the standard choice, and in a heatwave 1 or 2.5 tog is cooler still. People who feel the cold may find 7.5 tog comfortable in a cool summer.
Is 9 tog too hot for summer?
Yes, 9 tog is too hot for summer for most adults. It sits between 7.5 and 10.5 tog, which makes it an autumn to spring weight. For summer, go down to 4.5 tog. You'll mostly see 9 tog on children's duvets, where it's the winter option.
What tog do most hotels use?
Hotels usually use a mid-weight duvet, around 10.5 tog, because their rooms are heated all year and guests have different preferences. A mid-weight duvet with the room thermostat doing the rest suits more guests than a heavy winter duvet.
To get the same feel at home, pair a 10.5 tog duvet with crisp white bedding and swap to 13.5 tog only if your bedroom gets cold. Our microfibre duvet in 1 to 15 tog comes in single, double, king and super king, with hypoallergenic hollowfibre filling stitched in channels so it stays evenly spread. It's machine washable, so you can keep it as fresh as a hotel would.
