How to Measure Blinds for Your Windows

Complete guide for standard and bay window blinds measurement

Introduction

Measuring your windows correctly is the key to getting perfectly fitted blinds. Whether you are installing blinds in your home or office, accurate measurement ensures better appearance, smooth operation, and proper light control.

This guide will walk you through simple methods to measure both standard windows and bay windows.

Standard Windows Measurement Guide

Inside Mount (Recess Fitting)

Inside mount blinds are installed within the window frame. This gives a clean and modern look.

How to Measure

Measure the width and height of the window recess carefully. Always take measurements at three different points:

  • Width: Top, middle, and bottom
  • Height: Left, middle, and right

Use the smallest measurement to ensure proper fitting inside the frame.

Important Tips

  • Always use a steel measuring tape for accuracy
  • Do not make any deductions yourself
  • Keep measurements exact to avoid fitting issues

Outside Mount (Exact Fitting)

Outside mount blinds are installed outside the window frame. This is useful for better light blocking and full coverage.

How to Measure

Measure the total area you want the blind to cover, including extra space around the window.

For better results:

  • Add extra width on both sides
  • Extend the height above the window frame

Recommended Overlap

To reduce light gaps:

  • Add at least 70 mm at the top
  • Add around 50 mm on each side

Things to Consider

  • Check for obstacles like grills, handles, or AC units
  • Make sure there is enough space for installation

Important Note for Roller Blinds

For roller blinds, the total width (including brackets) is slightly wider than the fabric width.

This means:

  • The fabric area may be slightly smaller than the full blind width
  • Keep this in mind when measuring for exact coverage

Bay Window Measurement Guide

Bay windows require more careful measurement because of their shape. Each section must be measured separately for accurate fitting.

Angled Bay Windows

For angled bay windows, each panel should be measured individually.

Suitable blinds include:

  • Wooden blinds
  • Vertical blinds
  • Aluminium blinds
  • Pleated blinds
  • Roller blinds

Make sure each section is measured correctly based on its angle and size.

Square Bay Windows

Square bay windows are easier to measure but still require separate measurements for each section.

You can use:

  • Wooden blinds
  • Vertical blinds
  • Aluminium blinds
  • Pleated blinds
  • Roller blinds

Each window panel should be treated as a separate unit for best results.

Common Mistakes to Avoid

To ensure accurate measurement, avoid these common errors:

  • Measuring only once instead of multiple points
  • Using flexible tape instead of steel tape
  • Not considering mounting type
  • Ignoring extra space for outside mount
  • Forgetting obstacles around the window
