Get the right measurement for every window

Step-by-Step Measuring Guide

Step 1 – Choose Mounting Type

Inside Mount: Your window recess must be at least 100 mm deep

Outside Mount: Make sure your architrave or wall space can accommodate the bracket height (148 mm)

Step 2 – Measure Width

Inside Mount: Measure the width at the top of the inside frame 

Outside Mount: Measure from edge to edge of the architrave or your desired coverage

This is your bracket-to-bracket width – not the fabric width. We’ll handle the deductions for you.

Step 3 – Measure Drop

Inside Mount: Measure from the top of the recess to where you want the blind to finish

Outside Mount: Measure from the top of the architrave or wall down to your desired drop

Step 4 – Choose Control Sides

Decide which side each blind will be controlled from (left or right) as you face the window.

Step 5 – Check for Obstructions and Select Roll Direction

Look for window handles, locks, or winders.

Inside Mount: Front roll is usually best to avoid these

Outside Mount: Back roll for closer fabric position

Step 6 – Label Your Windows

Start at your front door and number windows clockwise. Include room names for easy reference (e.g. Living Room, Bedroom 2).
