To ensure the best possible fit, always measure the visible glass and
do not include the beading or rubber seals in your measurement.
Measuring The Width
Take three measurements of the width, at the top, middle and the bottom of the window. If there is any variation always use the
shortest width to order your blinds. If the windows are particularly large you can take intermediate measurements to check.
Reminder:
Do not include any of the beading or rubber seals in your measurement.
