Turn Comforter into Duvet Insert: Easy DIY Tutorial

Emma Jul 01, 2026

Transforming a comforter into a duvet insert can be a practical and cost-effective way to update your bedding. A duvet insert, also known as a duvet cover, is a lightweight, removable cover that houses your comforter, offering a clean, stylish look and easy care. Here's a step-by-step guide on how to make this conversion, ensuring a perfect fit and a polished finish.

Before you begin, ensure your comforter is large enough to fit your bed and that it's not too thick, as this could make it difficult to insert into the duvet cover. Also, consider the weight of your comforter. Duvet inserts are typically lighter than comforters, so if your comforter is very heavy, it might not be suitable for a duvet cover.

Choosing the Right Duvet Cover

Selecting the right duvet cover is crucial for a successful conversion. The cover should be slightly larger than your comforter to allow for easy insertion and to prevent bunching. For standard bed sizes, a duvet cover that's 2-4 inches larger on each side than your comforter should suffice. For example, if your comforter is a standard full/queen size (86" x 86"), consider a duvet cover that's around 90" x 90".

Also, consider the fabric and design of the duvet cover. Cotton or linen duvet covers are breathable and durable, while microfiber or polyester covers are easy to clean and maintain. Choose a design that complements your bedroom decor and offers the level of warmth and comfort you need.

Measuring Your Comforter

Before purchasing a duvet cover, measure your comforter to ensure a perfect fit. Lay your comforter flat on the floor and measure the length and width from top to bottom and side to side. If your comforter is not square, measure both the longest and shortest sides to ensure the duvet cover can accommodate it.

Don't forget to consider the depth of your comforter. If it's too thick, it might not fit into the duvet cover. Most duvet covers can accommodate comforters up to 12 inches thick, but if your comforter is thicker, you may need to look for a deeper duvet cover or consider other options.

Preparing Your Comforter

Before inserting your comforter into the duvet cover, give it a good shake to fluff it up and remove any wrinkles. This will help ensure a smooth, even fit in the duvet cover. If your comforter is machine washable, consider washing it before insertion to remove any dust or allergens.

If your comforter has a top and bottom, make sure to insert it with the right side facing out. This will ensure that the design or pattern on your comforter is visible through the duvet cover.

Once you've chosen and prepared your duvet cover and comforter, it's time to insert the comforter into the duvet cover. This process is similar to making a bed, but with a few extra steps.

Start by laying the duvet cover flat on your bed or the floor. If the duvet cover has a top and bottom, make sure the right side is facing up. Unzip the duvet cover, if applicable, to prepare it for the comforter.

Aligning the Comforter

Carefully place your comforter on top of the duvet cover, aligning the edges of the comforter with the edges of the duvet cover. This will ensure a smooth, even fit and prevent the comforter from shifting inside the duvet cover.

If your comforter is not square, you may need to fold it slightly to fit it into the duvet cover. Make sure to fold it evenly on both sides to maintain a balanced look.

Inserting the Comforter

Once your comforter is aligned with the duvet cover, carefully fold one corner of the comforter and the duvet cover together. Then, fold the opposite corner in the same way. This will create a neat, fitted corner that prevents the comforter from shifting.

Repeat this process with the remaining two corners. Once all four corners are folded, carefully lift the duvet cover and comforter together and place them on your bed. Smooth out any wrinkles and adjust the fit as needed.

Securing the Duvet Cover

If your duvet cover has a zipper, zip it closed to secure the comforter inside. Make sure to zip it all the way around to prevent the comforter from slipping out. If your duvet cover does not have a zipper, you can use safety pins or tie it closed with ribbons or strings, if applicable.

Some duvet covers have ties or elastic bands at the corners that can be used to secure the comforter inside. These can be helpful in preventing the comforter from shifting, but they may not be necessary if the duvet cover fits well.

Congratulations! You've successfully transformed your comforter into a duvet insert. Enjoy your new, stylish bedding. Regularly washing your duvet cover will keep your bedding fresh and clean. When it's time to wash, simply remove the comforter, wash the duvet cover according to the care instructions, and reinsert the comforter once it's dry.
