Measuring for Net Curtains
Net curtain width
When measuring the width of your window for your net curtain, you must measure the recess width. This is shown by the horizontal arrow in the diagram to the right. We recommend you measure the width in several places and then take the shortest measurement. For appropriate fullness/gather in your net curtain, we recommend multiplying your calculated width by 2.
Net curtain height
When measuring the height of your window for your net curtains, you must measure the recess height. Again, we recommend you measure the height in several places and then take the shortest measurement.
Measuring for a Curtain Track or Pole
To fit a curtain track or pole correctly, measure the width of the window plus 30/40cm (12-16″), this will ensure your curtains will comfortably cover your window. Fit your track or pole approximately 15cm (6″) above your window recess and centre ensuring you have 15-20cm (6-8″) either side of the window.
Measuring for Curtains
Curtain width
- Measure the full length of your track or pole (without its finials).
- Depending on the type of curtain you are looking for, you will have to adjust your measured width as follows:
- For eyelet curtains, multiply your calculated width by 2.
- For pencil pleat curtains, multiply your calculated width by 2.
- For tab top curtains, multiply your calculated with 1.5.
- Add another 1.0″ to your total width measurement to ensure your curtains overlap in the middle when closed.
Curtain length
- Decide where you want your curtains to fall, measure from the top edge of your curtain track/pole to:
- Sill length, measure to 0.5″ above the windowsill;
- Below windowsill, measure to 6.0″ below the windowsill; and
- Floor length, measure to 1.0″ above the floor.
- For eyelet curtains, write down your measurement and add 1.5″. This is the distance from the inner edge of the eyelet to the top edge of the curtain.
- For pencil pleat and tab top curtains, write down your measurement.

Measuring for Blinds
Measuring windows with a recess
- Use a metal tape and measure the recess of the window at three different points, as it may not be the same along the entire recess. Measure at the top, middle and bottom and use the smallest measurements as your width guide.
- To measure for the length of the blind, use the metal tape and measure from the top of the recess to the windowsill at 3 different points and note the narrowest point. For vertical blinds, we recommend you reduce the length by 1cm to prevent the fabric from catching on the sill.
Measuring windows without a recess
- Use a metal tape and measure across the window width, adding an extra 10cm (4″) to the total width to allow a 5cm (2″) overlap either side of the window to block out light effectively. For roller blinds add a further 5cm (2″) to the width to allow room for the operating mechanism.
- Decide where you want the bottom of your blind to end and measure the length of the window from the top of the fitting to this point.
