Choosing the Right Duvet Tog Based Upon the Temperature

If you’ve browsed our range of duvets recently, you may have noticed a new addition at the top left hand side of the page.

We’ve added a regional ‘tog forecast’ which recommends the tog rating that will be best suited to you based on the temperature in your area.

A duvet’s tog rating basically rates how warm it is. The higher the rating, the warmer the duvet will be.

It’s important to note that the higher the tog rating doesn’t necessarily mean a thicker duvet, as things such as the filling, softness and weight are all taken into account.

(Also bear in mind that silk duvets aren’t measured by tog rating as they are made from floss. These are measured by weight in grams per square metre instead.)

For example, while a natural duvet may seem a lot lighter than a synthetic one, they may still have the same tog rating because natural duvets have much better thermal properties.

Duvets generally range from 4.5 togs (with 4 tog used for baby and children’s bedding), which are very cool and lightweight, up to 15 tog duvets which are super cosy.

  • 4 tog – These duvets are more or less only used in bedding for children and toddlers, as children get much warmer in bed at night than adults. These duvets are perfect for cots and smaller beds all year round.


  • 4.5 tog – This is the perfect tog rating for the summer months, where many of us can often struggle to sleep due to being too warm. Even if you aren’t actually kept awake, the hot weather can make you toss and turn during the night, so if you find sleeping in summer a problem, opting for a cooler light Summer duvet might be the answer!

  • 7.5 tog – A 7.5 tog duvet is also acceptable for summer due to it’s light weight, but it can also be used in Spring if you prefer a cooler duvet.

  • 10.5 tog – While we recommend buying different duvets to suit the different seasons, if we had to recommend just one it would probably be a 10.5 tog duvet. This is because it is appropriate for both spring and autumn, and possibly even winter if your house is well insulated. A perfect all year round duvet.

  • 13.5 tog – This is probably the most popular tog rating as it keeps us cosy and warm during the winter, although many people make the mistake of using one all year round, when a cooler duvet may be better.

  • 15 tog – 15 tog duvets are at the really heavy duty end of the scale, and will keep you very toasty in bed, even during the winter. These are the warmest duvets available, and for this reason they aren’t for everyone. However, they may be useful in older properties where the insulation perhaps isn’t as good.
