How-To Guide: Measuring, Fitting & Caring for Interior Window Shutters
How Do I Measure My Windows for Shutters?
You’ll need a metal tape measure, a pen, and paper. A spirit level is also helpful to check for uneven walls or window frames.
Always measure in millimetres (mm) for accuracy. Avoid rounding up or down.
Measure the width at the top, middle, and bottom of the recess
Measure the height on the left, centre, and right
Use the smallest measurement for both width and height
This ensures your shutters fit neatly inside the recess.
Measure the overall width of the area you want the shutters to cover
Measure the height from top to bottom
Add extra coverage if you want light bleed reduced
Outside mount shutters are ideal for shallow recesses or uneven walls.
Yes, but bay windows, arches, circles, and angled windows are more complex. We recommend a professional survey for these to ensure a perfect fit.

Whole-house installations: usually half to one day
How Do I Adjust Shutter Louvres?
Tilt the louvres to control light levels
Open panels fully for maximum daylight
Close panels for privacy and insulation
Shutters give you precise control throughout the day.

Will Shutters Help With Insulation and Energy Efficiency?

Shutters can help reduce external noise, especially when fully closed, though they are not soundproof.
