Comforters are among the most crucial items in a bedspread. Is your king comforter too small for king bed? Since comforter sizes can vary, choosing the proper one can be difficult. If you don't choose your comforter carefully, it can reach the floor or merely touch the mattress' edges. This post will help you solve this problem.

Can King Comforter Too Small For King Bed?

Depending on the fabric, a standard king comforter may not be a perfect fit for a king bed. Thus, it's crucial to choose a comforter when measuring one that doesn't exactly match the dimensions of the king bed.

We suggest you go for an oversized comforter to have full coverage for your bed. This provides enough room for the comforter to completely cover your king bed without seeming saggy or lumpy.

Plus, going for oversized options can be beneficial in the long term. Some king bedding sets are only functional until you give them a wash for the first time. They might not react well in the washing machine, resulting in shrinkage and unusable for your king-sized bed.

Sizes of comforters are not uniform, unlike those for mattresses. The dimensions of a king-size comforter from different brands may vary, and some may provide bigger alternatives for thicker mattresses. But in general the comforter size of a king bed is 102 x 86-88 inches.

Despite being a loose bedding item, comforters cannot simply be placed on a different size bed. For instance, a twin comforter could hang too low for a twin XL size mattress. Same as with an Eastern king, a California king mattress' sides might be too long.

The fill and thickness of the comforter can also impact how it lies on the bed. If the comforter is filled with something fluffy like down, there's a chance it won't cover the entire bed because of its expansion.

How To Measure Your Mattress Sizes

Finding the ideal king size comforter dimensions might be facilitated by being aware of the dimensions of your mattress. This way, you can easily read the product's specifications while doing a quick web search, making the choosing process much faster and increasing the chance of getting the right size comforter.

You may estimate the breadth of your comforter by multiplying both sides by the width of your mattress. For instance, a twin-size mattress with a 10-inch thickness would have a width of 38 inches plus 10 inches plus 10 inches, or 58 inches overall.

If your bed has a footboard, remember to factor it in when determining the perfect length for your comforter. A footboard may interfere with the hanging of certain comforters that are intended to hang over your bed's foot.

Other Factors To Consider While Choosing A King Comforter


To cover the side of the mattress, your comforter's width should be consistent with the thickness of your mattress. Mattresses typically range in thickness between 9 and 12 inches. Almost any commercial comforter options will readily match anything in this price range.

Suppose your ultra-luxurious mattress measures over 15 inches thick; go for a Cal king or king comforter. These are the perfect sizes for bigger mattresses.


How breathable the comforter is may depend on its fabric. You will be more comfortable if your comforter has holes for air to circulate through. This feature will come in handy, especially during the summer.

Compared to synthetic fibers like polyester, natural and organic comforters with textiles like high-quality down, wool, and cotton are more breathable. The rule of thumb to stay warm, if you're on a tight budget, is with a comforter made of synthetic materials.


While some people may not think a comforter's appearance matters, others find that beginning the day wrapped in cheery designs or modern prints makes them happier. Although down comforters are typically white, you may jazz them up with bright solid colors or reverse patterns, making them the center of attention of your bedroom.
