Window Blinds Measuring Guide

How To Measure for Blinds

These measuring instructions apply to all types of blinds.

  • For accurate measurements always use a metal tape measure.
  • Take measurements in millimetres.
  • Choose whether you want your blind to fit inside the recess of your window or hang outside the recess overlapping the window.
  • Always specify the width first, followed by the drop.

Blinds hanging inside the window recess

  • Measure the width of the window recess in three places as shown below.
  • Measure the drop by taking the measurement from the top of the recess to the window sill in three places, as shown below.
  • Use the smallest measurement.
  • We will make all adjustments to ensure your blind fits perfectly.

Blinds hanging outside the window recess

  • Measure the exact area you would like the blind to cover as shown below.
  • To minimise light leakage we recommend the blind overlaps by at least 50mm each side.
