For Face Fitted Screens:
Measure the height and width as per the diagrams. These measurements relate to the “open space” i.e. the space created once the window is open.
Please note; if the window has a bevel (a sloping edge) measure to a point where the bevel becomes a flat surface.

For Recess/Reveal Fitted Screens:
Measure the full width and height of the window reveal/recess as per the diagram.
Width - measure between the two side walls at the top of the reveal. Take measurements on the top and bottom and use the shortest measurement.
Height - measure between the underside of the top sill (brick work) and the window sill. Take measurements on the left and right and use the shortest measurement.

Convert your measurements from inches to millimetres
