Choosing the Right Duvet Tog Based On the Temperature

A tog rating tells us how warm it is. The higher the rating = the warmer the duvet will be.

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

A natural duvet may seem a lot lighter than a synthetic one. However, it may still have the same tog rating. This is because natural fillings have much better thermal properties.

Duvets generally range from light and breathable 4.5 tog weights up to 15 tog double duvets which are super cosy for winter. Read our buying guide to choosing the right duvet based on temperature:

What is a 4 tog duvet?

4 tog 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 low-tog duvets are perfect for cots and smaller beds all year round.

A 4.5 tog double duvet can also be thought of as the perfect summer duvet tog where we might struggle to sleep due to being too warm.

Even if you aren’t being 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.

Spotlight on: Silentnight Cooler Summer Duvet

Keep cool with our low-tog lightweight duvet which is made especially for the summer months. The Silentnight Cooler Summer Duvet is filled with light fibres so it won’t feel heavy or restrictive, allowing heat and humidity to escape. The soft-touch covers are moisture-wicking to help keep you at a comfortable temperature.

What is a 7.5 tog duvet?

A 7.5 tog duvet is also acceptable for summer due to its lightweight, but it can also be used in Spring if you prefer a cooler duvet.

What is a 10.5 tog duvet?

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

What is a 13.5 tog duvet?

You might be wondering what tog duvet in winter to choose from. A 13.5 tog duvet or above will keep you cosy and warm when the temperature dips. However, some people make the mistake of using one all year round, when a cooler duvet may be better suited for improving your sleep quality.
