Calculating Drapery Weight Formulas

Fabric weight affects how a drapery hangs, how it stacks, and which rod and hardware you'll need. Use this chart as a quick reference when specifying linings and face fabrics. Most drapery linings fall in the 2–4 oz range; heavier linings and face fabrics require sturdier support.

Fabric Type Weight per Square Yard
Linings & Interlinings
Drapery Lining 2–4 oz
Interlining 5–6 oz
Blackout Lining 6–10 oz
Bump Lining 12–14 oz
Face Fabrics
Silks 2–4 oz
Chintz 2–4 oz
Printed Cottons 4–6 oz
Linens 6–10 oz
Jacquards 10–14 oz
Velvets 14–18 oz

Weights are approximate and may vary by manufacturer. Always confirm with your workroom or fabric supplier.
