How to Measure Inside Mount

The treatment fits inside the window frame.

STEP 1

Measure the width inside the window opening at the top, middle and bottom. Record measurements. 

STEP 2

Measure height inside the window opening at the left, right and center. Record measurements.

STEP 3

 How to Measure Outside Mount 

The treatment fits outside the window frame.

STEP 1

Measure the desired width. To minimize light leakage, the shade should overlap the window opening at least 2” on each side. Record measurements.

STEP 2

Measure the desired height. Allow for enough space for mounting brackets above the window and enough overlap at the bottom to avoid a light gap. Record measurements.
