Inside Mount

- Width Measurement
Order width includes the width of the valance.
Measure the top width inside the window frame and round down to the nearest 1/8 inch.
Order at the exact opening size with no deductions.
The factory will apply a small deduction of approximately 1/8 inch (3.2 mm) during production to ensure a safe and proper installation.
Attention: Please check if your windows have a splayed or recessed frame. If they do, measure the shortest width and use that measurement when placing your order; otherwise, the shades may not fit in the frame.
- Height Measurement
Order height includes the height of the valance.
Measure the middle height inside the window frame and round up to the nearest 1/8 inch.
The order height can be slightly larger than the exact opening height, as the length can be fine-tuned by setting the upper and lower limits.
Depth
For the standard valance, the minimum required depth is 3 7/8 inches (9.8 cm).
For the cassette valance, the minimum required depth is 4 inches (10.2 cm).
