Arched Shades

Measuring your windows doesn’t have to be tricky — follow these simple tips to get accurate measurements every time:

1. Use a steel tape measure. It’s the most accurate tool for this job.

2. Keep the tape straight and taut. Avoid sagging or bending.

3. Read carefully in 1/8" increments. Always round up (e.g., if a measurement is just under 25-3/8", round up to 25-3/8").

4. Decide on inside or outside mount. This will affect the measurements you provide.

5. Check the example pictures below. Choose the window type that looks most like yours to guide your measurements.

6. Measure the width in three places: top, middle, and bottom.

   • For inside mount, provide the smallest measurement.

   • For outside mount, provide the largest measurement.

7. Measure the overall height: Measure from the bottom of the window to the highest point of the arch.

8. Measure the straight-side height: Measure from the bottom of the window to the point where the straight vertical side ends and the curved arch begins. Enter both measurements in the quote form; the arch height will be calculated automatically.
