How to Measure a Window Recess for Shutters

Recess depth tells you how much clear space is available for an inside-mounted shutter.

Check your recess depth before measuring

As a simple guide, allow approximately 70mm of clear recess depth for an inside-mounted plantation shutter. Check the shallowest usable depth and measure to the first obstruction that could interfere with the shutter, such as a handle, winder, lock, key, flyscreen or other window fitting.

If you have around 70mm or more of clear space, you can generally continue with the inside-mount measuring instructions.

Have less than 70mm, or an obstruction in the recess? An inside mount may still be possible depending on the frame choice and where the obstruction sits. See our Managing Window Obstructions guide for the detailed clearance requirements.

Find the front reference point

Measure from the front face of the recess inward toward the window. Use the same reference plane around the whole opening.

Examples of obstructions

Security boxes, locks, winders, and handles.

Measure to the first obstruction

Stop at the first handle, lock, flyscreen, mullion or moving window part that could conflict with the shutter. This is the usable depth.

Measuring to obstruction

Check several locations

Measure near the top, centre and bottom on both sides. Use the shallowest clear measurement when checking frame suitability.

Operate the window

Open the sash and use the handle or winder. Make sure the moving parts do not enter the space you are counting as clear depth.

Before ordering: if your recess is less than approximately 70mm deep, or contains handles, winders, locks, flyscreens or other obstructions, check our Managing Window Obstructions guide before finalising your inside-mount measurements.
