Determine Inside Mount or Outside Mount
Angled blinds or shades that are inside mounted will be cut to hang entirely within the window
- We recommend inside mount whenever possible
- Neat, streamlined look
- Usually best for energy efficiency
Angled blinds or shades that are outside mounted will hang outside your angled window opening, overlapping the edges
- We recommend outside mount for out-of-square windows, and for windows with minimal mounting depth or obstructions within the frame
- Minimizes light gaps, giving you better light control and privacy
Measuring for Inside Mount
Note: Inside-mounted angled blinds and shades will have a small deduction automatically applied by the manufacturer, to ensure proper fit.
Width
- Measure at the depth within the frame where you'll install your brackets
- Measure width at the top, center and bottom of the rectangular portion of your window opening; you will not take any measurements from the angled portion for this step
- Record the smallest measurement (to the closest 1/8") as your Width
Height (Tall Side)
- For angle-top windows: Measure the height of the "tall side" of the window opening, from the bottom edge to the top corner of the angled portion
- For angle-bottom windows: Measure the height of the "tall side" from the top edge to the bottom corner of the angled portion
- Record the measurement (to the closest 1/8") as your Height
Short Side Height
- For angle-top windows: Measure the height of the "short side" of the window opening, from the bottom edge to where the angle starts
- For angle-bottom windows: Measure the height of the "short side" from the top edge to where the angle starts
- Record the measurement (to the closest 1/8") as your Short Side Height
Angle Length
- For angle-top windows: Measure the length of the angled line, from where the angled portion of the window starts to its top corner
- For angle-bottom windows: Measure the length of the angled line, from where the angled portion of the window starts to its bottom corner
- Record the measurement (to the closest 1/8") as your Angle Length
Measuring for Outside Mount
Note: Outside-mounted angled blinds and shades will have no deductions taken at the factory. They will be made according to your exact measurements.
Width
- Measure the area you want to cover, from left to right, in only the non-angled section of the window
- Make sure your measurement overlaps the window opening by at least 2" on both sides
- Record this measurement as your Width
Height (Tall Side)
- For angle-top windows: Measure from the top corner of the "tall side" of your shade to the bottom of the window opening
- For angle-bottom windows: Measure from the bottom corner of the "tall side" of your shade to the top of the window opening
- Add the amount you want your shade to overlap (we recommend at least 2" on each side)
- Record this measurement as your Height
Short Side Height
- For angle-top windows: Measure from the top of the "short side" of your window (where the angle starts) to the bottom of the window opening
- For angle-bottom windows: Measure from the top of the window opening to the bottom of the "short side" of the window (where the angle starts)
- Add the amount you want your shade to overlap (we recommend at least 2" on each side)
- Record this measurement as your Short Side Height
Angle Length
- Measure the length of the angled side of your window and record this measurement as your Angle Length
