Measuring for Curtains

To help you overcome your curtain hang ups, we’ve put together a guide on how to measure for curtains the expert way. Everything is easy, once you know how.

How to Measure the Width


Firstly, use a metal tape measure to give yourself the most accurate measurements then measure your curtain pole or track, not the window itself, to work out the width you need, ignoring the decorative finials on the pole end.

We recommend that your pole or track should be between 15cm and 30cm wider than the window, to maximise the light!

You also need to take into account how much ‘gather’ you want, with no gather the curtains will be tight and flat against the window.

For this, it is important to note that all of our ready made curtains are priced per pair, the sizes stated on our website are for the width and drop of each curtain panel and there are 2 of these curtains this size in each pack.

For curtains with full gather when closed, the pole/track measurement is the required width of each curtain panel.

How to Measure the Drop


Measuring curtain length or 'drop' depends on where you'd like your drapes to end. If you want your curtains to be level with the windowsill then measure from the pole/track to 1cm above the sill itself.

For curtains that fall below the windowsill, measure to around 15-20cm beneath the windowsill. A good tip is if your window has a radiator below it, measure to about 3cm above the radiator’s top to allow the heat to circulate.

If you are looking for full-length curtains, we recommend measuring from the pole/track to around 1cm above the floor.

However, if you want to create a luxurious look that’s also popular with designers, you could be more generous with the amounts of fabric and allow your curtains to pool on the floor.

How to Measure for Headings

When working out the overall length of your curtain you need to take into account the curtain heading, which is the gathered fabric at the top of the curtain.

For tracks, we recommend that curtains finish about 5cm above the top of the track, so measure 5cm upwards from the track glider eyelet.

For curtain poles, measure from the top of the pole to your chosen end point, depending on which look you are going for with the curtain length.

However, if you intend to hang pencil pleat curtains from your pole, and want to make a feature of the pole, measure from the eye of the curtain ring.
