How to Choose the Right Tog Rating for Your Duvet

What Is a Tog Rating?

Tog is the unit used to measure a duvet's thermal resistance ā€” in other words, how warm it will keep you. The higher the tog, the warmer the duvet. It's a simple scale, but choosing the right tog for your needs makes a real difference to the quality of your sleep.

The Four Main Tog Ratings Explained

4.5 Tog ā€” Lightweight Summer Duvet

A 4.5 tog duvet is ideal for warm summer nights or for those who naturally sleep hot. It provides just enough coverage without causing you to overheat. If you tend to kick off your duvet in the night during warmer months, a 4.5 tog is the answer.

Best for: Summer, warm bedrooms, hot sleepers.

7.5 Tog ā€” Medium Weight Spring & Autumn Duvet

A 7.5 tog duvet sits in the middle of the range, making it a versatile choice for the transitional seasons. It's light enough for a mild spring evening but warm enough for a cool autumn night.

Best for: Spring, autumn, mild climates, temperature-regulated bedrooms.

10.5 Tog ā€” All-Season Duvet

The 10.5 tog duvet is the UK's most popular choice ā€” and for good reason. It strikes the perfect balance between warmth and breathability, making it suitable for most of the year in a typical British home. If you're only buying one duvet, this is the one.

Best for: Year-round use, average sleepers, most UK homes.

13.5 Tog ā€” Extra Warm Winter Duvet

A 13.5 tog duvet is designed for cold winter nights, draughty bedrooms, or anyone who simply feels the cold. It provides maximum warmth and cosiness when the temperature drops.

Best for: Winter, cold bedrooms, cold sleepers, older homes with less insulation.

Can I Use Two Duvets Together?

Yes ā€” a popular trick is to combine a 4.5 tog and a 9 tog duvet (or similar) to create an "all-seasons" system. Use them separately in summer and autumn, and clip them together in winter for maximum warmth. It's a flexible, cost-effective approach.

Other Factors to Consider

  • Filling: Down and feather fillings tend to be warmer for their weight; synthetic fillings are hypoallergenic and easier to wash.
  • Bedroom temperature: A well-insulated modern home may need a lower tog than an older, draughtier property.
  • Personal preference: Some people simply run warmer or cooler than average ā€” trust your instincts.
  • Bed partner: If you and your partner have different preferences, consider two single duvets rather than one double.
