Comforter Sizes and Dimensions (With Chart)

A cozy comforter can make all the difference in creating a good night’s sleep.

It can help keep your temperature in balance at night and enhance your overall comfort. Plus, it can enhance the overall vibe of your room. 

However, finding the right size can be a challenge. While the ideal comforter size typically matches your mattress size, other factors, such as personal preference for overhang, additional mattress depth, and type of foundation, can affect your size choice. You may need a larger comforter than your mattress dimensions would suggest. 

We’ve put together an easy-to-follow comforter size guide to help you find the right option for your sleep needs.

Comforter vs. duvet: key sizing differences

It’s easy to confuse a comforter with a duvet as they’re similar in appearance and function. Both add comfort, encompassing warmth and weight, to your bedding.

However, they’re very different in their setup and in how you choose the ideal size.

Duvets consist of two parts: an insert and a duvet cover. The duvet cover functions much like a pillowcase does for a pillow and is interchangeable depending on style preferences.

You can easily remove it for washing or to change to a different style. 

A comforter is a single one-piece cover that covers the entire bed. It also has more overhang.

While you want some overhang with a duvet, you don’t usually need as much coverage along the sides of the mattress as you would with a comforter.

Calculating ideal overhang (mattress thickness + box spring)

The right comforter has enough overhang to cover your mattress and any box spring without dragging on the floor.

This ideal fit helps you avoid drafts from a cold room at night and provides freedom of movement to prevent a battle of covers with your bed partner.

To determine the ideal overhang, consider your mattress height and frame height. Measure the following:

• Mattress width: Mattress widths don’t vary much from standard measurements, but use a tape measure to get the exact width. You don’t want to make assumptions about width when considering comforter sizes.
• Mattress height (or depth): Measure the height of the mattress from the bottom edge to the surface, including any mattress toppers.
• Box spring and frame drop (optional): Whether you want to cover your bed’s foundation with a comforter overhang depends on your box spring and frame type and whether you use a bed skirt. If you want to hide them with a comforter, measure to ensure the drop is sufficient.

Add the mattress height to the box spring and frame drop number to create your drop length. 

Ideal Comforter Width = Mattress Width + (2 x Mattress Drop Length) 

Sizing solutions for high-Profile and deep mattresses

A high-profile bed frame and a deep mattress can complicate comforter sizing.

If your mattress is over 15 inches in depth, from the very bottom to the very top, you may find it challenging to find the right comforter size. A high-profile bed frame can cause similar challenges.

After you determine your ideal overhang and look for comforter sizes, a good rule of thumb is to go up one size from your mattress size.

For example, consider a king-size comforter for a deep queen mattress or a full-size comforter for a deep twin mattress.

This is because an extra-deep mattress or a higher-profile frame requires more from the comforter, leaving less drape.

Going up a size is often the easiest solution in these cases. However, use your measurements you’ve calculated as the overall guidelines for ideal width.

How to prevent comforter shrinkage in the wash

Upkeep and overall maintenance for your comforter aren’t too demanding. You won’t need to wash it as much as you do your sheets. However, you do want to launder your comforter at least once a month, mainly because it doesn’t have a cover like a duvet. 

When it’s time for your comforter’s laundry day, here are a few extra precautions to take to avoid the risk of shrinkage in the wash:

• Start by following any care instructions on the tag. This information will be a good starting point for comforter care needs.
• Keep an eye out for stains and spot-clean them as they arise. 
• Look along the seams for any signs of damage and repair them before washing the comforter.
• In general, avoid hot water as it can cause shrinking; use cold or lukewarm water instead. 
• Choose a mild detergent only and use less than you normally would to avoid soap residue staining the comforter. 
• Consider running an extra rinse cycle due to the comforter’s size. 
• Maintain the comforter’s fluffiness by adding tennis balls or dryer balls to keep the fabric fluffy. 
• Depending on your washer and dryer and the size of your comforter, you may need to use a laundromat to clean it. Stuffing a king-size comforter in a home washer or dryer will cause uneven cleaning.

Summary checklist for buying the perfect size comforter

A comforter can be a luxurious addition to your sleep. When looking for the perfect size comforter, consider this checklist:

• Establish a baseline for your sizing needs, including your mattress depth and width, whether your frame is included, and whether you use a bed skirt. 
• Use a tape measure to get the exact widths, rather than relying on generic size estimates for your mattress.
• Get your ideal drop height, based on where you want your mattress to fall.
• Achieve the ideal comforter width with this calculation: [Mattress Width] + [Drop Height] + [Drop Height].

FAQs

How much should a comforter hang over the sides of a bed?

On average, a comforter should have 6 to 12 inches of overhang. There may be more if you have a box spring to cover. To find your ideal comforter width, double your desired overhang depth, then add that amount to the actual width of your mattress.

Can you use a king comforter on a queen bed?

You can use a king comforter on a queen bed, especially if you have a deep queen mattress. Your foundation can also play a part. If you have a high-profile frame, a king comforter can be the perfect size. 

How do you choose a comforter size for a deep mattress?

For a deep mattress, measure from the top of the mattress to where you want the comforter to drop, then multiply that measurement by 2. Then add that number to the width. That gives you the ideal width. Generally speaking, you may want to go up a size. For example, a full-size deep mattress may work best with a queen comforter, and a queen-size deep mattress may work best with a king comforter.
