Water Bed sizes are the 'old fashioned' style and size, rather than the newer ones that accept standard mattress bedding. Sizes given do not include the padded railings which add approx. 3 to 4 inches to each side and the foot of the bed.

Pillow sizes are the size of the actual pillow. Generally add 4 to 6 inches to the pillow length for a pillow case, and double that if you are going to double fold the open edge.
