Is a 10.5 Tog Duvet Too Warm for Summer?

The weather in the UK is quite unpredictable which makes it a great talking point but it can be a nightmare to know how you’ll sleep at night – will you need a hot water bottle or a fan? As Summer approaches, you’ll want to swap out your thick Winter duvet for a thinner Summer one, but how thin should you go? What do tog ratings even mean? We’re here to explain all of that and more so you can get a good night’s rest.

What is Tog?

Tog refers to the insulating qualities of the duvet, which can be affected by the thickness of the duvet as well as the material inside.

Common duvet fillings include:

  • Feathers
  • Down
  • Wool
  • Synthetic materials
  • Silk

Tog ratings are classified on a scale of 1 to 15, with 15 trapping the most heat and 1 trapping the least, so the lower the tog, the cooler you’ll be at night with that duvet. Since natural fillings are natural insulators for geese, ducks and sheep, they tend to be thinner duvets than those made with hollowfibre or other synthetic materials that require more stuffing to reflect the insulating qualities of natural materials. Although the tog will change according to the density of the filling.

Incidentally, feathers and down from ducks and geese from Scandinavian countries and Canada are even more insulating than those found in Europe due to the colder climate necessitating more insulation to keep the birds warm when surrounded by snow and ice. This can also make them more expensive, as they’re highly sought after, and fewer are needed to fill cold-weather duvets.

Silk duvets aren’t measured by tog but by grams of silk per metre-squared, so if you’re looking to invest in a silk duvet but aren’t sure which to go for, around 250 grams per square metre equates to a cool duvet of less than 4.5 tog, while more than 600 grams per square metre makes a warmer duvet at around 10 tog.

Tog Ratings

Generally, most duvets come in 5 different tog levels.

  • 4.5 tog
  • 7 tog 
  • 10.5 tog
  • 13.5 tog
  • 15 tog

While each person sleeps differently and has a different sleeping body temperature, generally speaking, 1 – 7 tog is for adults with a high sleeping body temperature or hot nights in Summer, while 10.5 – 15 tog duvets are for use in the colder months or for people who have lower sleeping body temperatures.

It should be noted that this advice is strictly for adults, as babies should never sleep with duvets due to their inability to regulate their body temperature, and children under 10 years of age shouldn’t have a duvet over 4.5 tog as they are also hot sleepers.

What Tog is Best for Summer?

With temperatures in the UK dropping to 10 – 15 degrees Celsius at night in Summer, you might feel that a thinner Summer duvet isn’t strictly necessary. However, as houses tend to hold onto heat for longer, the temperature of your bedroom will likely be warmer than the temperature outside. That’s why Summer duvets tend to be 4.5 – 7 tog for most adults, although those who are particularly hot sleepers at night, or have well-insulated and thus very hot bedrooms might require 1 – 4.5 tog, or just a sheet to cover them.

A 10.5 tog duvet may be too warm for Summer for many people, as it’s on the higher end of the tog scale and will keep you well insulated overnight. However, if you have a very cold room, for example with single-glazed windows or an old property without insulation, 10.5 tog might be ideal.

Ultimately, the best duvet for Summer depends on the temperature of your bedroom as well as your body temperature, so if you’re too hot and not sleeping well with a 7 tog duvet, you should try a lower tog, and if you’re still waking up shivering in the night, you should opt for a higher tog duvet. What’s more, the material of your duvet cover may be causing you to sweat or shiver overnight, so make sure you’ve chosen the right duvet cover for Summer before you go out and buy a new duvet.

What Tog is Best for Winter?

The same rules apply for Winter duvets as for Summer duvets, as your personal sleeping style is the most important factor, followed by the temperature of your bedroom. Although, since nightly average temperatures in the UK in Winter fall to between 0 and 5 degrees Celsius, for most people, a duvet with a tog rating over 13.5 is ideal for Winter months.

For naturally cold sleepers, however, a 15 tog duvet is often the warmest you can buy and will keep you snug through the cold weather.

Changing bedding isn’t exactly a fun chore, so most of us don’t want to faff around at the turn of each season bringing a different tog duvet out of the loft; luckily, there are all-season duvets so you don’t have to.

All-season duvets tend to be between 7 and 10.5 tog as this is the mid-range insulation between the best tog duvet for Summer and the best tog duvet for Winter. For many people this is a perfect compromise as through Spring and Autumn the duvets are often perfectly suited, and through Summer you can untuck yourself more or add a fan to your room, while in Winter you can snuggle up more to keep warmer or add a hot water bottle or extra soft blanket to keep you even cosier.

Some all-season duvets actually comprise two duvets, usually one 4.5 tog duvet and one 9 tog duvet. That way you can use the 4.5 tog duvet when the weather is hot, the 9 tog duvet at the change of seasons and the combined 13.5 tog duvet during the cold Winters. This gives you more flexibility if you’re in an area where the temperature changes drastically from season to season, but does still require some storage room for one of the duvets while they’re not being used.

Hotels tend to use all-season duvets to cater to all tastes and sleeping styles in order to keep the majority of their guests comfortable, although more luxury hotels may have options so you can ask for a thinner or thicker duvet from reception.

Since goose and duck feather and down duvets are naturally insulating, you’ll most likely want a duvet made from synthetic materials like hollowfibre during the Summer months in order to stay cool overnight. However, what material you choose changes the tog and the thickness of the duvet.

If you like a very thin duvet but still want to have some warmth, down duvets are perfect for keeping you warm without being particularly thick or heavy. If you prefer a thick and soft duvet to snuggle up with but don’t want to get too hot, your best option is a microfibre or hollowfibre duvet.

Bear in mind that hollowfibre duvets are also lightweight, so they’re often more easily stored, especially in vacuumable bags. However, if you like a heavier duvet or blanket while you’re sleeping, a denser filling or choosing feathers instead may be more beneficial for your sleep.
