Did you know that there is a very easy way to discover how warm your new duvet will be? A super thick, heavy duvet may not actually be the warmest option. This is why every duvet is given a tog rating which is printed right on the label.
A tog is a number that measures how well the duvet will retain and insulate heat. The higher the tog number, the warmer your duvet will be. Pretty simple!
Fun Fact: The Shirley Institute, a cotton research association in Manchester, England, first developed tog numbers and the tog test in the 1940s. It is a system that is still used to rate the thermal resistance on duvets and carpet underlays.
Tog Numbers Explained
Before you pick the best tog number for you, we wanted to make sure you know exactly what a tog is. Tog stands for Thermal Overall Grade and the scale ranges from 1 to 15 with 1 being the coolest, lightest rating and 15 being a very warm, insulated duvet. Most duvets fall into the 4.5 to 13.5 tog range so anything cooler or warmer may require a special order.
How to Pick a Tog
There are two main factors that will help you decide what tog rating is best for you:
- The temperature in your room
- How warm you like to be when you sleep
In the summer, you will want a duvet with a lower tog number to help you stay cool during the night. A colder bedroom in the winter may drive you to get a duvet with a higher tog so that you stay cosy and warm.
Every person is different when it comes to their preferred night-time temperature. Some love to be extra warm at night and would therefore love a higher tog duvet. Others would rather be nice and cool, enjoying a lower tog duvet. Think about your personal preferences when you assess blanket tog numbers.
Now that you understand tog numbers and how to choose the best tog duvet for you, you are ready to go shopping! Pick your tog number wisely and you are sure to feel comfortable all night long.
