Fitted sheets

Fitted sheets are sized by the name of the size of mattress they are intended to fit (USA mattress sizes are used below). In recent years mattresses have become increasingly deeper, and more people are using thick mattress pads of sheepskin, down, and so on. Many fitted sheets are not deep enough to fit these newer styles.

The “height” of a fitted sheet is determined by the depth of what makers call the “pocket.” Pockets are usually shallower on fitted sheets for twin beds (say, 8½ inches) than for the larger sizes (say 10½ inches). Fitted sheets are available with pockets as deep as 12 or even 14 inches.

Mattress size	Width in inches	Length in inches
twin	39	75 or 76
long twin	39	80
full or double	54	75 or 76
queen	60	80
king	78 or 79	80
California king	72	84
