To be sure of the best possible fit, take time to measure your window carefully. We suggest using a metal tape measure for accuracy. The first step is to decide whether you want your curtains to hang from a track or pole, both of which should be positioned 15cm (6 inches) above the window and extend 15-20cm (6-8 inches) either side.
Fit the track or pole before taking measurements.
Measure the total width of the track or pole (excluding the finials) – do not measure the window unless it is wall-to-wall. Don’t forget to allow for overlap – this is an additional measurement, normally 2.5cm (1 inch) that allows the hanging curtains to overlap in the middle when they are closed.
Before measuring the length, decide whether you want your curtains to fall to the sill, below the sill or to the floor. We suggest that:
Sill length curtains finish 1.25cm (1/2 inch) above the sill.
Curtains that fall below the sill finish 15cm (6 inches) below.
Floor length curtains finish 1.5cm (1/2 inch) from the floor (although you can create a romantic, Bohemian look by having them longer so that they actually trail on the floor).
Measuring curtains for tracks
Measure from the top of the track.

Measuring curtains for poles
Pencil pleat curtains: Measure from the eye – the small metal ring at the bottom of each curtain ring. This will prevent the pole or rings from being obscured by the curtain.
Tab top and eyelet curtains: Measure from the very top of the pole.
