Buying curtain fabric without doing the maths usually means coming up short, or paying for metres you never use. This free curtain fabric calculator works out the exact metres you need from your window size, fullness and heading style.
How to Use This Tool
- Measure your window width, then your drop length from the rod to where the curtains should end.
- Pick your fullness, from a light gather to a luxe, extra-full look.
- Choose your header type, eyelet or pencil pleat.
- Press Calculate Fabric Needed and read the exact metres to buy.
Why It Helps
Curtains look best with the right amount of gather, and fabric is too dear to waste. Knowing the exact metres before you order means neat, full-looking curtains with no awkward shortfall and no costly offcuts left over.
