Calculating Drapery and Fabric Weight

 

1)    Fabric Weight - Some fabric samples list on the back of the swatch the weight listed in Ounces/SqYd (Ounces per Sqaure Yard). Call the manufacturer for the weight if not listed anywhere.

 

2)   Lining Weight Most drapery linings are 2oz - 4oz - Per Square Yard.

 

 

         Finding Drapery Weight Formula:

Total Square Yards = (Total Yards x 36 x Fabric Width) 1296 (1-Sqaure Yard)

Weight = Total Square Yards x Weight in ounces per SqYd) 16 oz in 1 Lb

Example: 32 Yards of 54 wide fabric weighing 14 oz/SqYd

Total Square Yards = (32 x 36 x 54)= 62,208 1296 = 48 SqYds

Weight = (48 x 14oz) = 672 16 = 42 Lbs

 

 

         Finding Lining Weight Formula:

Total Square Yards = (Total Yards x 36 x Fabric Width) 1296 (1-Sqaure Yard)

Weight = Total Square Yards x Weight in ounces per SqYd) 16 oz in 1 Lb

 

Example: 32 Yards of 54 wide lining weighing 6 oz/SqYd

Total Square Yards = (32 x 36 x 54)= 62,208 1296 = 48 SqYds

Weight = (48 x 4oz) = 192 16 = 12 Lbs
