BE CAREFUL: Our curtain weight calculator is provided to assist you in choosing curtain tracks and fixing. But please use as a guide as all curtains are made differently and you may have more fabric or weights in your curtains.

This is our curtain calculator and is based on very generic assumptions. It works out the amount of fabric required for standard curtains assuming you are using 35cm for hems, to the nearest width and then creates a square meterage of material and multiplies that by the weight of your fabric fabric.
