Calculating curtain fabric for bulk orders is not only a width-by-drop exercise. Buyers need to connect finished size, fullness, heading, fabric roll width, repeats, lining, shrinkage, MOQ, samples, and packing before comparing factory quotations.
For bulk curtain programs, fabric calculation should start from finished curtain size, fullness, heading, roll width, pattern repeat, lining route, and size breakdown by SKU. A clear calculation file helps factories quote fabric, sewing, MOQ, and lead time consistently.
Bulk orders should be calculated from finished curtain width and finished drop, not only window opening size. The factory needs to know whether each SKU is a single panel, pair set, room package, or made-to-measure item. This prevents underquoting when the buyer later confirms final panel size.
Fullness changes fabric consumption immediately. A 1.5x flat panel, 2.0x pinch pleat, and 2.5x sheer curtain can use very different fabric quantities even when the finished window coverage looks similar. Review curtain heading styles before locking the calculation because heading choice affects both fabric and sewing time.
For curtain fabric wholesale programs, roll width determines whether the factory can cut each panel cleanly or needs joined seams. Buyers should ask for usable width after selvage, fabric direction, shade-lot control, and whether wide-width fabric is available for tall drops or hotel rooms.
Pattern repeat, stripe direction, blackout lining, interlining, and expected shrinkage can all change consumption. Current sourcing conversations around layered textiles and functional contract materials make this more important: the fabric stack must be calculated together, not as separate decorative layers.
A practical RFQ table should list SKU, room type, finished width, finished drop, quantity, fabric, color, heading, fullness, lining, packaging, and label requirement. When the buyer provides this table, the supplier can calculate fabric rolls, sewing capacity, carton volume, MOQ, and lead time with fewer assumptions.
The lowest price is not useful if the calculation is unclear. Ask the factory to state roll width, assumed fullness, seam plan, wastage allowance, lining route, sample basis, and packing volume. Keep these notes with the approved sample so bulk production follows the same assumptions.
