Choose your Down Duvet in 4 Simple Steps

Step 1 - Duvet Size

The first step to finding the down duvet of your dreams is knowing what size you need. Do you have a single, double, king, super king or emperor sized bed? If you're unsure, use this chart to find out which size duvet will best fit your bed:

Size Imperial (inches) Metric (cm)
Single 54 x 79 135 x 200
Double 79 x 79 200 x 200
King 91 x 87 230 x 220
Super King 102 x 87 260 x 220
Emperor 114 x 92 290 x 235

For a double bed, we suggest a duvet that covers the entire width of your mattress, plus a few additional centimetres. If you are unsure which size is right, choose one that is wide enough to keep you well covered during the night.

Step 2 - Tog Rating

How warm is your ideal duvet? Every down duvet has a tog rating, a measure of its insulating power. The higher the tog rating, the warmer the duvet.

In the UK duvets are sold in increments of 1.5 tog, from 3.0 tog for a very light, summery duvet, up to 18.0 tog for a heavy winter duvet. The given values represent a minimum and actual values may be up to 3.0 tog higher. Because tog rating is performed on plain duvets in a lab, fitting a duvet with a cover and wearing nightclothes can effectively increase the tog rating.

There are several personal factors to consider when determining the ideal tog rating of your new duvet, such as the climate where you live, your house's heating system and whether you often find yourself too hot or too cold at night.

To learn more about which tog rating is best suited to your needs, visit our Choosing the Right Tog page for more information.

Many people choose to have two duvets at home –a light duvet for the summer and a thicker one for the cold winter months. If storage or budget limitations restrict you to owning one duvet, we suggest a Spring/Autumn duvet which provides the best of both worlds and can be used year-round.

Tog values on Downduvet.co.uk range from 4.5 tog to 15.0 tog. To help you in your duvet selection, we’ve created this helpful chart:

6.0 Tog: SummerPlus duvet

9.0 Tog: Spring/Autumn duvet

12.0 Tog: Winter duvet

15.0 Tog: WinterPlus duvet

Step 3 - Down Quality

The higher the quality of the down, the more insulated the duvet. Quality of down is determined by its size and elasticity.

We have found that most people want a duvet which is light but will still keep them warm. Down offers more insulation while taking up less space than feathers or alternative fillings, making it the perfect material for light, warm duvets. For this reason all of our duvets contain at least 90% down.

Step 4 - Ticking

Ticking is the outermost layer of a duvet, the fabric which encases all the down and other filling. It is important that ticking is strong and tight so that dust does not get in and feathers don't stick out, while remaining soft and supple to ensure comfort and provide a great night's sleep.

Cotton is the most commonly used ticking material for down duvets. Close-woven cotton allows for ventilation while preventing leaks.

We measure the quality of duvet ticking in Ne. An Ne value of 1 means there is one pound worth of yarn in a piece of yarn 840 yard long. The denser the threading of ticking, the higher the Ne value and the more comfortable the duvet. In the interest of selling only the highest quality products, we only offer down duvets with ticking between Ne 60 and Ne 160.
