FAQs about How to Measure a Bay Windows for Blinds

Can I use standard blinds for my bay windows, or do I need custom-made blinds?

It’s highly recommended to opt for custom-made blinds for bay windows. Standard blinds may need to fit the unique angles and curves of bay windows properly, leading to gaps and efficient light control.

 How do I measure the angle between the windows in my bay window setup?

To measure the angle between windows, 

  • Use a protractor. 
  • Place the protractor in the corner where the windows meet, ensuring it’s flat against both surfaces. 
  • Read the angle measurement where the two sides of the protractor align.

My bay windows are curved. How can I measure them accurately?

For curved bay windows, use a flexible tape measure to follow the curve precisely. Measure both the width and height of the bay window. Additionally, measure the radius of the curve to ensure a perfect fit for your blinds.

What should I do if my bay windows are uneven or not perfectly square?

If your bay windows are uneven, measure the depth at multiple points to accommodate irregularities. For non-square windows, provide measurements for each section separately. Many custom blind manufacturers can work with non-standard window shapes.
