The first thing to do when measuring for your mini blinds is to determine if you need inside mount or outside mount. Inside mount will fit the blinds within the window frame, while outside mount will fit the overlap of the window opening.
Inside mount
To find the width, measure the exact distance between the inside surfaces of the window frame at the top, middle, and also the bottom then use the narrowest width you receive with your measurements. To find the length, measure the exact distance from the inside surface at the top of the window to the bottom sill at the left, middle, and the right then use the longest length. If you prefer for the blinds not to touch the windowsill, you should deduct 1/4″. If there isn’t a sill, then you should measure the length to the point where the blinds are to reach.
Outside mount
To find the width, measure the exact distance between the outermost points where the blinds are to be placed. For the best of light control, the measurement should extend 3/4″ beyond the window opening on each side. To find the length, measure the exact distance from where the top of the blinds are to be placed to the top of the windowsill. If there isn’t a sill on your window, then measure the length to the point where the blinds are to reach.
Measuring for your blinds is very important, as you’ll need the measurements to order the blinds. Most companies will deduct for the brackets at the factory, then all you’ll need to do once you receive your blinds is to install them – which is easy to do as well…
