Roller Blind Measuring Guide

Roller Blind Measuring Guide


Roller blinds are a versatile and stylish addition to any room. To ensure a perfect fit, follow our simple step-by-step guide to measuring your windows.

1. Tools You'll Need

  • Metal tape measure (for accuracy)
  • Pen and paper (for noting down measurements)

Pro Tip: Use the Right Tools: Always use a metal tape measure for accuracy. Fabric or plastic tape measures can stretch over time, leading to inaccurate measurements.

2. Decide Your Blind's Position

Before you start measuring, decide if you want your blinds:

  • Inside the window recess (Recess Fitting): The blind fits within the window opening.
  • Outside the window recess (Exact Fitting): The blind covers the window and overlaps onto the wall.

3. Measuring for Inside Recess Blinds (Recess Fit)

  • Width: Measure the width of the window recess in three places (top, middle, and bottom). Use the smallest measurement.
  • Drop: Measure the drop of the window recess in three places (left, middle, and right). Use the smallest measurement.

Pro Tip: Check for Obstructions: Ensure there are no obstructions like window handles, tiles, or decorative mouldings that might interfere with the operation of the blind.

Pro Tip: Consider the Depth: If your window recess is shallow (less than 60mm), you might want to consider fitting the blind outside the recess to avoid any obstructions.

Note on Fabric Size for Recess Blinds: When you order a recess blind, the fabric width will be approximately 30mm to 35mm narrower than the width you provide. This reduction accounts for the mechanisms, brackets, and ensures the blind operates smoothly within the window recess. Always keep this in mind when visualizing how the blind will look once installed.

4. Measuring for Outside Recess Blinds (Exact Fit)

  • Width: Decide on the overlap for the blind on each side of the window recess (a minimum of 7.5cm overlap on each side is recommended). Measure the overall width, including the overlap.
  • Drop: Decide on the overlap for the blind at the top and bottom (a minimum of 7.5cm overlap at the top is recommended). Measure the overall drop, including the overlap.

Pro Tip: Consider obstructions like radiators or window sills when deciding on the drop.

Pro Tip: Account for Overlaps: If fitting outside the recess, allow for an overlap on all sides to ensure maximum light blockage and privacy.

Double Check Your Measurements

Always measure twice to ensure accuracy. Remember, it's better to spend a little extra time measuring than to order the wrong size!

Pro Tip: Double Check: Always double check your measurements before ordering. It's better to spend a few extra minutes checking.

Note Down Your Measurements

Write down your measurements clearly and keep them handy. When ordering, specify whether your measurements are for inside or outside recess.

Pro Tip: Document Everything: Write down each measurement as you go, labelling them clearly. This will help avoid confusion when ordering.

5. Ordering Your Blinds

Ordering your bespoke roller blinds is a breeze with these simple steps:

  • Fill in Your Sizes: Input the exact dimensions ensuring you double check for accuracy.
  • Select Your Fitting Type: Choose how you'd like your blinds to be fitted. Recess or exact.
  • Decide on Chain Control Location: Pick which side you prefer your chain controls to be.
  • Select Your Chain Type: From metal to plastic, choose a chain that matches your style.

Pro Tip: Always ensure you select the right unit of measurement, either cm or inches. Remember, cm is set as the default and is our most popular choice. Make your selection carefully to ensure a perfect fit!
