Sizing Guide
Accurate measurement is crucial for proper fit and function. Please follow these guidelines:
- Inside Mount: For shades mounted inside the window frame, the selected width of the roller shade should be 1/4 inch less than the measured window frame width. The selected height should be larger than the measured window frame height.
- Outside Mount: For shades mounted outside the window frame, the selected width of the roller shade should be 4 inches wider than the measured window frame width. The selected height should be 4 inches larger than the measured window frame height.
Note: Fabric width will be approximately 1 inch narrower than the total shade width. A tiny light gap may exist on each side with inside mount. For 100% blackout, an outside mount is recommended.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Shade does not stop smoothly. | Mechanism may need adjustment or is stiff. | Gently pull the shade all the way down, then slowly raise it all the way up. Repeat a few times to reset the spring mechanism. |
| Light leakage around the edges. | Inside mount installation or incorrect measurements. | For inside mounts, some light leakage is normal. For 100% blackout, consider an outside mount or ensure precise measurements for inside mount. |
| Shade is difficult to raise or lower. | Mechanism is jammed or spring tension is off. | Ensure no obstructions are blocking the shade's movement. Try resetting the spring mechanism as described above. If issues persist, contact customer support. |
