Please note that getting the right size fitted sheet for any mattress is very important. If it is too small, it obviously will not go on correctly. If it is too big, the fitted sheet will not stay on the mattress and can move while you are sleeping. This will cause it to bunch up and eventually come off. Remember always to find an XL sheet if you have a twin XL or full XL mattress for a proper fit.

How do I measure for a fitted sheet?

Using a tape measure is the easiest way to find the measurements of your mattress. First, measure the width of the mattress. Then you can proceed to measure the length and depth of the mattress. After taking down all your measurements, look at the dimensions of the fitted sheet on its packaging. It should match up to those that you wrote down within a few inches.

Also, think about your mattress and if you are using a topper. This may add a few inches to measurements, as well.


How do I choose a fitted sheet?

There a few deciding factors in choosing sheets in general, such as thread count, fabric, and colors/prints. The higher the thread count, the more luxurious and durable the sheets are. Fabrics and colors/prints are to your preference. Sheets can be satin, silk, cotton, or even flannel. 

Should the fitted sheet match bedding?

Some people prefer the sheet to match all of their bedding. Again, this is all in what you prefer for overall appearance. You could always choose a neutral color that pairs well with any color/print you may choose for the top sheet, blankets, or comforter on your bed. 

In Conclusion

The sizing of a fitted sheet depends on the size of the mattress. From a twin-sized bed to a California king, each mattress has different dimensions, as do the sheets. Always factor in whether the mattress has a topper or even a waterproof cover. Remember to add an extra five inches to any mattress that may be XL in length.
