Measure the curtain track or pole width, not the window. If fitting a new track or pole, this should extend 15cm to 20cm either side of the window and at least 15cm above. Pinch pleat curtains have permanent sewn-in pleats; this means that you will be unable to adjust the width of the curtain once it's made. It's important therefore that you are accurate when measuring the width of the track or pole.
For a curtain pole simply measure the width of the pole between any finials or end caps, that is your correct curtain width.
For a standard curtain track simply measure the full width of the track, that is your correct curtain width.
If your track has an overlap in the centre measure the full width of the track (a) and the width of the overlap (b). Add the two together and that is your correct curtain width.
Curtains can be hung either to the floor, to a sill or to below the sill. We suggest that curtains finish either;
When using a curtain pole, measure from the underside of the decorative ring to where you want the curtain to finish at the bottom.
When using a curtain track, measure from the top of the track to where the curtain is to finish at the bottom.
Our eyelet heading curtains will fit poles up to 30mm in diameter. Simply measure from the top of the pole to where you want the curtain to finish at the bottom. We will make the curtain with 3cm of fabric above the top underside of the eyelet where it sits on the pole. We add this automatically so simply measure from the top of your curtain pole.
