There are several elements to think about when purchasing sheets, but none are quite as important as getting the sizing right. That's why we've made a convenient bed sheet sizes chart so you know the right sheet sizes for your mattress dimensions. If your mattress is larger than standard size (perhaps your mattress includes extra padding or you're using a thick mattress pad or mattress topper), you might have to size up. Avoid the annoyance of fitted sheets unhooking from the corners of your bed, and find the perfect sheets for a great night of sleep.

A particular way of folding and tucking while making the bed, known as hospital corners, is sometimes used when the bottom sheet is flat rather than fitted.
