How to measure an opening for a Roller Shutter

Measuring a roller shutter opening accurately is crucial to ensure that the shutter fits perfectly, providing optimal security and functionality. Start by measuring the width of the opening at three points: the top, middle, and bottom. Use the widest measurement as your width to accommodate any irregularities in the wall. For the height, measure from the floor to the underside of the lintel at both the left and right sides of the opening, and use the taller measurement. This accounts for any slope in the floor or variance in the opening's height.

Top Tips:

Use a Reliable Tape Measure: Ensure your tape measure is long enough and provides accurate readings.

Double-Check Measurements: Always measure twice to avoid any costly mistakes.

Consider the Space for Guides and the Box: Remember to account for the additional space needed for the roller shutter's guides on either side of the opening and the roll's housing box above.

Note Obstructions: Take note of any potential obstructions (like pipes, electrical boxes, or light fixtures) that could affect the installation or operation of the shutter.
