Curtain Length (Drop) Calculator
Enter your rail-to-floor height and pick the look you want — café, floor-kiss or full puddle — to get the exact finished drop and the fabric cut length to order.
Your window
Hem just touches the floor — crisp, tailored. Pinch pleat headings sit just below the rail, so the finished drop is adjusted accordingly.

The finished drop is what the curtain looks like hung. The cut length adds the top heading turn-over and a deep bottom hem — order to the cut length, not the finished drop.
Before you order
Measure rail-to-floor at several points along the width — Indian floors are rarely perfectly level, and a 2–3 cm difference is visible on a floor-kiss hem. Take the longest measurement for a tailored look. Ready-made curtains come in fixed drops (137 / 152 / 213 / 274 cm are common), so you may need to round to the nearest stock size or have them altered.
