Calculating a Quilt Size

Approximate mattress size:
(width x length)
27" x 52"     Crib
39" x 75"     Twin
54" x 75"     Double
60" x 80"     Queen
76" x 80"     King
72" x 84"     California King

To calculate quilt size, add the amount of drop (the part that hangs over the edge of the mattress) and the tuck (part that folds under the pillow).
