Indian mattresses come in three lengths (72, 75 and 78 inches) and four main widths: single 36", double 48", queen 60" and king 72". Measure the inside of your bed frame and choose the largest standard size that fits; a 75 × 60 inch frame takes a queen mattress (6.25 × 5 ft).

How to use this calculator
