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 length (height): from the top to the bottom of the window.

8. Measure the arch height:

   • Measure the total length of the window (top of arch to bottom).

   • Measure the length of the straight part of the window (bottom of arch to bottom).

   • Subtract the straight part from the total length — the difference is the arch height.
