# How to Calculate Drapery Weight Please follow the guidelines below when calculating drapery and fabric weight.

## Fabric Weight

Some fabric samples list on the back of the swatch the weight listed in Ounces/SqYd (ounces per square yard). Call the manufacturer for the weight if not listed.

## Lining Weight

Most drapery linings are 2oz - 4oz per square yard.

## Calculating Drapery and Fabric Weight

Use the formulas to calculate the drapery and fabric weight.

### Drapery Weight Formula

 Total Square Yards = (total yards x 36 x fabric width) ÷ 1296 (1 - square yard) Weight = (total square yards x weight in ounces per SqYd) ÷ 16 oz in lb Example 32 yards of 54" wide fabric weighing 14 oz/SqYdTotal square yards = (32 x 36 x 54) = 62,208 ÷ 1296 = 48 SqYdsWeight = (48 x 14oz) = 672 ÷ 16 = 42 lbs

### Lining Weight Formula

 Total Square Yards = (total yards x 36 x fabric width) ÷ 1296 (1 - square yard) Weight = (total square yards x weight in ounces per SqYd) ÷ 16 oz in lb Example 32 yards of 54" wide fabric weighing 6 oz/SqYdTotal square yards = (32 x 36 x 54) = 62,208 ÷ 1296 = 48 SqYdsWeight = (48 x 4oz) = 192 ÷ 16 = 12 lbs

### Fabrics by Weight

Contact the fabric manufacturer for your specific fabric weight.
