Steps to Measure a Window

To ensure you get the perfect fit for your window, follow these simple steps to measure accurately.

1) Face brickwork to measure the width of a new window. Measure at the top from left to right the middle left to right and the bottom left to right find your smallest size then -5 mm or up to 10 mm.

2) Rendered apertures: the same steps for brickwork, but ADD 5mm or up to 10mm as required.

TO MEASURE THE HEIGHT OF A WINDOW :

1) Face Brickwork: Measure from the underside of the lintel to the underside of the Cill and subtract minimum 5mm or up to 10mm.

2) Rendered aperture: measure from the underside of the render at the head of the window to the underside of the Cill and subtract a minimum of 5mm up to 10mm.

Always double-check your measurements for accuracy before proceeding.

If unsure, please get a professional window installer to check the measurements for you.

An industry standard is to give the width first followed by the height and the height always includes a Cill if you have one.
