Inside Mount

Inside mount blinds are ideal if you want a clean look. As the name suggests, they are mounted inside the jamb. To Measure:
Width
- Measure the width between the left and right window jamb at the top, middle, and bottom.
- Round the measurements down to the nearest 1/8"
- Record the smallest of the three measurments
Height
- Measure the height between the top and bottom window jambs in a few places
- Round the measurements up to the nearest 1/8"
- Record the laregest of the three measurements
Depth
- Depth refers to the ammount of space inside your window jamb where your blind will be installed (measured front to back)
- At the top of your window, extend your tape measure against your flat jamb until it is as far back as it can go (where your brackets will be installed). Record the measurement from there to the front face of the window jamb.
- Pay special attention for any obstacles (i.e. window cranks or handles) that will interfere with the blind. If there are any obstacles, take a measurement from the obstacle to the front face of the window jamb. If this measurement is smaller than the measurement taken at the top of the window, record this dimension as your depth.
Outside Mount

Outside mount blinds are installed outside the window frame, and extend past it. Outside mount blinds are ideal for windows that have shallow frames. They are most often installed on the face of the trim around a window or door. To measure:
Width
- Measure the overall width that you would like your blind to be.
- Make sure that the blind will cover the entire window for maximum privacy.
- Often times the overall width of your blind will be the same as the out-to-out measurement of your window trim.
- Blind will be supplied the exact size you specify, no adjustments to size will be made during manufacturing of outside mount blinds.
Height
- Measure the overall height that you would like your blind to be.
- Make sure that the blind will cover the entire window for maximum privacy.
- Often times the overall width of your blind will be the same as the out-to-out measurement of your window trim.
- Blind will be supplied the exact size you specify, no adjustments to size will be made during manufacturing of outside mount blinds.
