Measure Guide
Measure for DIY Shutters
A practical millimetre-by-millimetre guide for getting your shutter order right before it reaches the factory.
Start configuringUse the smallest width and height
Measure each opening in three places: top, middle and bottom for width, then left, centre and right for height. Use the smallest measurement for recessed shutters.
- Use a steel tape measure
- Record measurements in millimetres
- Measure every window separately
Check squareness
Measure both diagonals. If they differ by more than 6mm, choose a frame style that can hide uneven reveals.
- Inside mount works best for square reveals
- Z frames help cover small gaps
- Face fit is safest for shallow or uneven openings
Send photos when unsure
A quick photo of the window, sill and obstructions helps us confirm the right mount and frame before the order is made.
