Measurements of Super Size Waterbed Sheets

Super Single Bed

• The super single waterbed measures 48 inches wide by 84 inches long. The size of the bed gives you 9 inches more in width than that of a twin bed -- or 7 inches less than the width of a double bed. It is 9 inches longer than a twin or a double bed.

Bedsheets

• Super single sheet sets come with one flat sheet, one fitted sheet and one standard pillow case. The flat sheet and the fitted sheets are sewn together at the bottom to prevent the sheets from coming off the bed. Flat sheets measure 55 inches wide by 96 inches long. Fitted sheets measure 48 inches wide by 84 inches long for a smooth fit. The standard pillowcase measures 20 by 32 inches.

Pocket Types

• Waterbed sheets have different-size pockets to accommodate different mattress heights. Generally, super single waterbed mattresses are 16 inches tall, and sheet sets with 16-inch-deep pockets fit underneath the mattress. However, depending on the manufacturer of the mattress and how much water you have in it, you may need a sheet set with 22-inch-deep pockets for the sheet to fit under the mattress securely enough to hold the sheets in place.

Comforters and Mattress Pads

• Mattress pads for a super single waterbed come with pockets or with an elastic band that fits underneath the mattress to hold the pad in place. Both types of mattress pads measure 48 inches wide by 84 inches long. Comforters for the waterbed are generally 79 inches wide by 92 inches long, but some styles might have slightly different measurements.
