Measuring Guide

How do I measure my window for curtains?

Measuring your window is easier than you think, if you follow our simple advice. For the most accurate measurements we recommend using a metal tape measure and preferably having your pole or track already fitted when hanging curtains outside your window. If you are hanging net or voile curtains, these are usually placed inside the recess of the window so that they can sit behind curtains or a blind. Virtually all curtains will be hung outside the window recess on a track or a pole, and many people will hang voile panels, or custom made voile or lace curtains on a pole too. the information below will help you measure both for the recess measurement, and for curtains hung outside the window frame.

Measuring inside window

Measure from left to right and from top to bottom, within your window frame.

Measure from left to right and top to bottom

Measuring width outside window

Measure the width of your track or pole. Ideally your track or pole should extend 15cm either side of your window to allow for optimum stack back.

Measuring for curtain drop

Where your curtains fall is a personal preference, but there are generally three places the voiles can sit; window sill, below sill and floor. The general rule of thumb is to measure from the top of your track or pole, to where you want the curtain to finish. Please note our standard slot top heading is 4cm with a 1cm stand up.  If your rod or pole is wider than a standard tension rod then please do contact us as we would need to create a bespoke slot that is designed to fit your rod or pole. We would need to know the diameter of your pole and provide a quote for this.

Where to measure for the drop of curtains


How do I measure for a pair of voiles or curtains?

To measure your window for a pair of curtains is simple, and almost the same process as how to measure for a single curtain as explained above. You measure the width and  drop in the exact same way, but once you have your width measurement divide this by two and then use these two measurments seperately when entering into our website for gather options and prices. For example, a 100cm wide window would be halved to 50cm and this would be the number to enter in our calculator, you would then want to select that you want two of these once your gather is chosen.

How do I allow for gather in my nets & voiles?

Allowing for gather means the finished curtain size will not be flat to your window, and will create soft folds. Most curtains are sold in this way, but having flat pieces is something that is becoming more popular. We recommend 2.5x gather for all voiles and nets, however this is again personal preference and you may wish to allow for more or less depending on where your curtains are going. Our website allows you to enter your window measurements directly and then select which option of gather you would like, so there is no need to do the calculation beforehand. If you are replacing curtains and want to enter these measurements directly, then choose ‘I know the sizes I need’. For more information on gather and for some helpful suggestions visit our blog here.

Should I measure in inches or centimetres?

Legally, we have to sell your curtains in centimetres so all correspondence and quotes will be sent in this way, however if you would prefer to work in inches then you will see the option to use inches on the calculator when entering your window sizes. The easy way to convert inches to centimetres is to multiply the inch measurement by 2.54. So, for example, four foot, is 48 inches or 122cm.
