Measuring for Inside Mount
STEP 1: Measure the inside width at 3 locations - the top, middle and bottom. Record the smallest of the 3 measurements. This is your ordering width. We will make the necessary deductions (approx. 1/2").
STEP 2: Measure the height at 3 locations – the left side, middle and right side. Record the smallest of the 3 measurements. This is your order height. We will make the necessary deductions (approx. 1/4").
Measuring for Outside Mount
STEP 1: Measure the width of the area you wish to cover. If space allows we recommend adding 6-12" inches total (3-6" on each side) to overlap the window and avoid light gaps.
STEP 2: Measure the height of the area you wish to cover. This is your ordering height (from the top of your blind to the bottom of the vertical vanes). Remember to allow for the 1 7/8" of flat space needed for your mounting brackets. Generally 3" - 4" added to the height of your opening (including molding or framework you wish to cover) will allow you room to mount above the window frame.
