How To Measure For Curtains

A well fitting pair of curtains can complete the look of a room, as well as being practical by blocking outside light, and retaining warmth during the winter. At Closs & Hamblin, our expert home consultants will measure your existing curtains or window during your FREE home measuring service, but if you would like to submit your own measurements, please use the following guide.

Measuring Tips

Take time to measure you window carefully, and take the measurements several times to confirm the dimensions. We would suggest using a metal tape for accuracy.

Will your curtains hang from a track or pole? We recommend fitting the track or pole before taking measurements - they should be positioned 15cm (6 inches) above the window and extend 15-20cm (6-8 inches) either side.

Don't forget to tell us if your track has a cording system or overlap carrier.

Measuring Width

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.

If your curtains are to be hung from a track, do you want the curtains to curve fully around the edges of the track so they touch the wall?

Measuring Length

The style of heading, and whethr you choose track or poles your curtain has will determine where you measure from (see our handy diagram below).

Decide whether you want your curtains to fall to the sill, below the sill or to the floor.

- 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.




  • Measure the total width of the track or pole excluding finials (A)


  • On a pole, measure from the eye below the curtain ring (B)
  • For a track measure from the top of the track (C)
  • For eyelet curtains measure from the top of the pole (C)
  • For floor length curtains measure 1.5 cm (½”) from the floor, or measure 15 cm (6”) below the sill for shorter curtains
