② Outside Mount Measurement
How to Measure for Outside Mount
1.Measure the desired width of coverage.
We recommend adding 2–4 inches wider than the window frame.
2.Measure the desired height from the top mounting position to where you want the blind to end.

1.Order Width = Desired Coverage Width
2.Order Height = Desired Coverage Height
Outside mount blinds help block more light and make windows appear larger.
③ Window Depth Requirement
Check Your Window Depth
To install blinds inside the window frame, the minimum depth required is:
≥ 1.5 inches
If your window frame is shallower than this, we recommend choosing Outside Mount installation.Still unsure about your measurements?Send us a photo of your window and we’ll help confirm the size. Contact email: service@curtaincustom.com
