Calculating fabric for your curtains can be a complicated process. We published a helpful guide to how to measure for curtains and calculate fabric requirements, but now we have gone a step further and developed a calculation for you. Simply enter the details of each curtain in the form below, using either inches or centimetres for all your measurements, enter the fabric width and any pattern repeat in the same measurement unit (inches or centimetres) and the calculation will be done for you. Please note that as this is an automated process it cannot take account of any savings that can be made by having less fullness or reducing hems. This calculator is in a testing phase, so please do let us know if you encounter any problems or need further help with calculating requirements in one of our fabrics. Please see below for a selection of our current curtain fabrics, details including width and pattern repeat can be found by clicking on the fabric. All fabrics can be ordered from our website in multiples of 1 metre. The calculator will give a result to the nearest 0.1 metre which can be rounded up to purchase from the website. Please note for half drop repeat curtain fabrics we suggest you add an extra half pattern repeat to the calculated figure before rounding up.
