Measure For Outside Window Mount
Width: Measure the exact distance from the outside edge of the left side of the window frame to the outside edge of
the right side of the window frame. Add an additional 3" to the width for optimal coverage.
Height: Measure the exact distance from the top outside edge of the window frame to the bottom outside edge of the
frame. For complete privacy, an overlap of at least 3" for horizontal blinds is recommended.
Note: Inside-mount vertical blinds and headrails will include ½" deduction in both width and height;
vertical vanes have no deductions.
