Curtain Fabric Requirements.
How many metres of fabric for curtains?
Use 2–3 times the window width in curtain fabric to get proper fullness and smooth draping. Standard curtain fabric requirements:Small windows → 2 to 3 metres of curtain fabric
Medium windows → 4 to 6 metres of curtain fabric
Large windows / patio doors → 8+ metres of curtain fabric
Curtain fabric depends on heading & style:
Light & sheer curtains (voile, net, organza) → less fabric (2x window width)
Heavy fabrics (velvet, blackout, thermal curtains) → more fabric (3x window width)
Pro Tip: Always round up your fabric measurements to avoid running short when stitching curtains or adding pleats.
