Why Does My Duvet Cover Not Fit?

Keeps duvets clean, and prevents them from stains, mushiness, and any rips that may harm their material. Duvet covers are needed for a duvet. But what if the cover you bought for your duvet doesn’t fit your duvet?

Well, read this article to the end, and we’ll tell you why your duvet cover doesn’t fit.

Why does my duvet cover not fit?

The duvet cover won’t fit because it’s the incorrect size for your duvet. The size disparity between your old and new comforters may mean that your duvet cover will be too small to fit over them. This is because the thickness of the comforter needs to be just right for the duvet cover.

When it comes to duvet covers, there are several reasons why they won’t fit your duvet.

Duvet sizes:

To keep the cover snug, choose a duvet with a 2-inch tolerance on both sides. If you want a perfect-fit duvet cover, choose a comforter 2 or 3 inches larger than your duvet cover.

Size differences between the bed and the cover:

Well, this is a common reason why people don’t get their covers to fit. Covers for duvets are made to fit duvets of the same size.

Choosing a twin-sized duvet cover for a queen-sized bed will not fit the duvet, since the cover is too tiny to accommodate the duvet.

Additionally, a king-sized duvet cover will not fit a twin-sized duvet since the cover is much larger.

Duvet covers that shrink:

When you wash your duvet covers more than once, they will shrink. So, always buy a duvet cover that is a little bit bigger than your comforter. If you don’t, it won’t fit later.

Should our duvet covers be so loose?

Duvet covers, on the other hand, are designed to suit a certain size duvet. Duvet coverings that are somewhat larger than your duvet will be loose.

Since the fabric of duvet covers shrinks after being washed, most people are told to buy loose duvet covers.

Also, when you buy duvet covers in a store, they might be a little big because they were made to fit perfectly on your duvet.

How do I fix a too-big duvet?

A typical issue with duvets is that many people are unsure of what to do if theirs is too large. In any case, if you want your duvet to fit inside the covers, you have several options available to you to choose from.

  • Sewing is one thing you can do to help. Sewing is very easy and a quick, effective way to fix a too-big duvet. Using safety pins is another quick solution to this problem.
  • You may also use the triple-sheeting method, which is often used by hotel personnel. It’s a quick and easy solution where you just keep draping the top layer of shit over the duvet.

How can you figure out what size duvet to buy?

To figure out what size duvet to purchase, you’ll need to take some measurements. On the other hand, there are a few more considerations about bed sizes that need to be taken into account. So, to help you understand, here are some of the steps:

Level of warmth wanted:

First, decide how warm you want your duvet cover and fillings. People can make duvet covers out of many different materials, such as cotton, polyester, and man-made materials.

High-quality down duvets are thought to be warmer and better at controlling heat, but people with allergies shouldn’t use them.

More space:

The comforter and mattress should be separated by extra space. The thickness of your mattress, on the other hand, determines how long and wide it is. For mattresses with a maximum height of 7 inches, this is OK.

Use the 11 x 15 rule to choose duvets with 11 inches long and 15 inches wider than the bed size.


The duvet, on the other hand, comes in standard sizes, even though the measurements can be different. In general, you are only allowed to use a double, full, queen, or king-sized duvet on a mattress between 9 and 11 inches in length. This restriction applies to all four types of duvets.

If your bed gets bigger, you might need to change the size of your duvet. For example, you need a full-size duvet to cover a large double mattress.

For duvets for double beds, the size of the cover will be between 81 and 87 inches. For Queen and King sizes, the cover will be between 89 and 100 inches.

Will a queen duvet cover fit a king comforter?

As far as we’re concerned, the answer is a definite yes. But there are several factors to bear in mind depending on your goal.

In terms of visual appeal and comfort, the size of a queen or king duvet may help you narrow down your options, but ultimately, it comes down to personal preference.

The sizes of mattresses from different companies are usually the same, but the sizes of beds of the same type can vary by more than ten inches. One comforter can slip out of a queen duvet cover and land on the floor, while another can fit into a king duvet cover.

Should the inside of the duvet be bigger than the cover?

As far as I know, it’s necessary to have a bigger duvet insert than a smaller duvet cover. Because duvet covers are made to be cleaned, the fabric will shrink when you wash them.

While your duvet and cover will be the same size, they will shrink by no more than five percent to ensure a snug fit. This is the only way to ensure that your duvet and cover would be a great fit.

Why do duvet covers lose their shape?

The duvet cover fabric can bobble or pill due to a surface flaw that consists of small fibers. The bobble makes the covers seem like they are covered with tiny thread balls.

For prolonged usage and cleaning, the fiber ends might be shattered, leading to minor knots and twisting. Some of the most prone to wrinkling include linen, cotton, polyester, and acrylic.


In general, duvet covers are manufactured to fit duvets of comparable size, however, there are situations when the dimensions of the two might vary. So, when you decide to purchase a comforter or duvet cover, it’s best to go for a size that’s a bit bigger or smaller.
