Fabric Calculator

To use our fabric calculator, simply enter the width of your track or pole, the finished length of your curtain drop (click here) for detailed instructions on how to measure for this) and the pattern repeat of your chosen fabric (which can be found in the fabric's description).

Please be aware that this calculator is only a guide for fabric amounts but is calculated as we do in store. For fabric widths we round up from 0.3 of a width to allow for a good fullness in your finished curtains, however this might not be necessary for dress curtains.

All metre values are rounded up to the nearest metre to ensure that you will have enough fabric for your project.

If you would like a breakdown of the values or have any queries, please don't hesitate to Contact Us.
