Width

Height

The width and height measurement should always include the cassette, valence, headrail or roller.

Important notice

The cassette, valence, headrail or roller will be the same width as the measurement given and the fabric will be shortened about 1/2 an inch on each side, which is why, for example, if the space to be covered is 60" in width, it is recommended to order 64" (or 2" extra on each side) to ensure that the entire window frame is covered, preventing any light from penetrating through any gaps.
