Measuring Tips
1. Use a steel tape measure for best accuracy.
2. Round each measurement to the nearest 1/8”.
3. Always record width (left to right) first, and then height (top to bottom).

If your window is larger you can choose two shorter shades instead. Having two shades give you an advantage to roll them up separately. The bead chain is on the right side by default.

Inside Mount:

Measure the window inside width and height. 

  • Use a metal tape measure, cloth ones can stretch and give you inaccurate measurements
  • Measure the window inside width and height. Don’t make any deductions. We'll deduct 3/8" from the order width to fit your window.
  • Ensure you have enough window depth, at least 2 3/8”.
  • Order Width= Window width
  • Order Height= Window height or bigger

Outside Mount:


  • Measure the window frame width and height.
  • Shade width= Window width + 3/4''
  • Shade height= Window height or bigger
