How to Measure for Windows: Ensuring Precision for Perfect Shutter Installation

Accurate window measurements are the foundation of flawless shutter installations. At North London Shutters and Blinds, we combine 15+ years of craftsmanship with sustainable British engineering to deliver sustainable wooden shutters that fit like a glove. This guide walks you through our proven measurement process, honed through thousands of successful window and shutter installations across North London.

Why Proper Measurement Matters

Ill-fitting shutters compromise aesthetics, functionality, and energy efficiency. Our survey of 500+ installations revealed that 68% of measurement errors occur in DIY attempts. With our 0.5mm tolerance standard, we guarantee shutters and blinds that:

Block 100% of light when closed
Reduce heat loss by up to 25%

How to Measure for Windows: 7-Step Process

Step 1: Determine Recess Depth

Measure from the window glass to the outer wall edge in three locations. Record the smallest measurement to ensure shutters don’t protrude.

Step 2: Width Measurements

Take three horizontal measurements:

Top of recess
Middle of recess
Bottom of recess

Use the narrowest width minus 10mm for clearance.

Step 3: Height Measurements

Measure vertically in three places:

Left side
Center
Right side

Subtract 5mm from the shortest measurement.

Step 4: Check for Square

Compare diagonal measurements corner-to-corner. Differences >5mm require special adjustments – contact our engineers at special shape shutters team via 020 3417 6465.

Window handles
Locks
Protruding tiles
