How to measure
The Height (H) is the distance from the underside of the top sill (lintel) to the bottom window sill. The Width (W) is the measurement between the two side walls of the reveal.
We advise taking 3 measurements for both height (left, middle & right) and width, (top, middle & bottom) to allow for any variations. In each case take the smallest measurement to determine the size of kit you need.
As long as your reveal measurements fall within a kit size, that kit will be suitable; e.g. if your window is W 1000 x H 900, the smallest kit will be right for you.
