What You'll Need

Step ladder (if needed)

01
Measure the Width

Measure the inside width of the window recess at three points: top, middle, and bottom. Windows are rarely perfectly square, so this ensures accuracy.

Important: Record the NARROWEST width measurement
02
Measure the Height

Measure the inside height of the window recess from the top of the recess to the sill. Take measurements at the left side, center, and right side.

Recommended: 100mm (4 inches) above, extend to sill or below
03
Check the Recess Depth

Measure the depth of the window recess from the front to the window glass. You need at least 50mm (2 inches) of depth for inside mounting.

Minimum depth required: 50mm (2 inches)
04
Check for Obstructions

Check for any handles, locks, or other obstructions that might interfere with the shutters operation. Measure their position and ensure the shutters will clear them when raised or lowered.

01
Measure the Width

Measure the width of the area you want to cover. For best light blockage, add 100-150mm (4-6 inches) to each side of the window frame.

Recommended overlap: 100-150mm (4-6 inches) on each side
02
Measure the Height

Measure from where you want to mount the brackets to where you want the shutter to end. Add 100mm (4 inches) above the window frame for mounting space and light blockage.

Recommended: 100mm (4 inches) above, extend to sill or below
03
Mark Bracket Positions

Ensure you have adequate wall space for mounting brackets. Check that there are no electrical wires or pipes behind the mounting area.

Pro Tips for Perfect Measurements

follow
Measure in Millimeters

Always measure in millimeters for the most accurate results. It's the industry standard.

follow
Use a Steel Tape

Fabric tapes can stretch and give inaccurate measurements. Always use a steel measuring tape.

follow
Measure Each Window

Even if windows look identical, measure each one separately as sizes can vary.

follow
Write It Down

Record all measurements clearly, labeling each window to avoid confusion.

follow
Check Twice

Always double-check your measurements before ordering to ensure accuracy.

follow
Consider Handles

Window handles can obstruct blinds. Measure their projection from the window.
