Our factory will make the following adjustments:
For inside mount, the total shade width will be 3/16" less than the ordered width. The fabric deduction will be 3/8" less than the ordered width. Do not adjust your measurements based on the inside mount deductions. Doing so may result in your shade not fitting.
For outside mount, the shade will be ordered width. The fabric deduction will be 3/8" less than the ordered width.
The height of the product will be slightly longer than ordered to allow pleats to hang freely and not sag, which is considered normal and will not affect the operation of your shade.
Deductions may vary +/- 1/8"
