How to Measure for Inside Mount

  • Measure the Depth: Measure your window frame for an inside mount. Minimum depth required: 3" (7.6 cm) for Cassette Valances.
  • Measure the Width: Place the tape inside the window frame and measure from left to right at the top, middle, and bottom. Keep the tape level and record each measurement. Use the smallest measurement and round down to the nearest 1/8" (0.125").
  • Measure the Height: Measure from top to bottom at the left, center, and right sides of the window frame. Keep the tape vertical and record each measurement. Use the largest measurement and round down to the nearest 1/8" (0.125").

Tips for Inside Mount
  1. The factory will make a small deduction of approximately 1/8" (3.2 mm) from the ordered width to help ensure a safe and proper fit.
  2. Check whether your window frame is bowed inward or outward. If it is, measure the narrowest width and use that measurement when placing your order. Otherwise, the shade may not fit inside the window frame.
  3. Ensure your window frame has sufficient depth: 3" (7.6 cm) for a Cassette Valance.
  4. Maximum Extension of the No-Drill Tension Mechanism: 15 mm (0.59 in).
