Measuring & Fitting Guide

Step-by-Step Instructions

PLEASE GIVE EXACT MEASUREMENT – THE MAKERS ACCEPT NO RESPONSIBILITY FOR ERRORS IN ORDERING

Just read the easy to follow instructions below. Then all you’ll need is a steel tape measure, not cloth tape – they stretch. But take care, accurate sizes are essential.

“This table is a guideline showing the amount (in mm) that will be deducted for each width and drop provided as a recess measurement.”

Blind TypeWidth (mm)Drop (mm)
Vertical Blinds1010
Metal Venetian Blinds100
Wooden Venetian Blinds100
Roller Blinds50

Please Note:

  • All measurements should be provided in cm or mm.
  • All our blinds are made with a 5mm manufacturing tolerance (width & drop).
  • Always use a metal rule when taking the measurements. Cloth ones can stretch giving inaccurate measurements.
  • Recess Size
  1. This is the measurement you need to make if the blind needs to fit inside the window recess. Measure the width and the drop in three different positions ensuring you provide us with the smallest measurement.
  2. We will make any necessary deductions to ensure the blind fits neatly within the recess of the window.
  • Outside Recess Size

3.  An exact size blind is also known as ‘pin width’ or ‘finished blind width’. This is the measurement you need to make if the blind needs to hang outside the recess overlapping the window. Decide how much you wish to overlap the recess at each side, we recommend at least 7.5cm at each side as well as the top and bottom so as to minimise as much external light as possible.

4.  Measure the width and the drop in three different positions ensuring you provide us with the smallest measurement. We will not make any deductions from the measurements provided.

Should you want to buy new louvres to use with your existing headrail, simply measure the length of the existing louvres from the very top of the material to the very bottom. We will not make any deductions from the measurements provided. 

Additional information when measuring for roller blinds and day night blinds. Please note  that the cloth width will be 35-40mm narrower than the overall size. Further to this if you are side fixing it is important to always state this as an exact measurement.
