How to Measure Windows for Perfect Blind Fit

The Importance of Accurate Measurements


Proper measurement is the most crucial step in ensuring your blinds fit perfectly. Even small errors can lead to light gaps or installation issues...



Tools You'll Need



  • Steel measuring tape (not cloth tape)

  • Pencil and paper

  • Step ladder if needed

  • Level (for checking square)



Inside Mount vs Outside Mount


First, decide which mounting style you prefer:



Inside Mount (Recessed Fit)



  • Fits within the window frame

  • Clean, built-in look

  • Requires sufficient depth in window frame

  • No drilling into wall needed



Outside Mount (Overlay Fit)



  • Mounts above or around window frame

  • Can make window appear larger

  • Better light blockage

  • Can cover imperfect windows



Step-by-Step Measurement Guide



For Inside Mount:



  1. Measure width at top, middle, and bottom

  2. Use the narrowest measurement

  3. Measure height at left, center, and right

  4. Use the longest measurement

  5. Check window frame depth



For Outside Mount:



  1. Decide how much overlap you want (typically 2-3 inches each side)

  2. Measure total width including overlaps

  3. Measure from above window to below sill

  4. Consider clearance for handles or locks



Common Measurement Mistakes to Avoid



  • Assuming windows are perfectly square

  • Measuring only once

  • Not accounting for window handles

  • Forgetting to note obstructions

  • Rounding measurements incorrectly



Special Considerations


Bay Windows: Measure each section separately...


Sliding Doors: Consider track clearance...


Skylights: Special measurements needed...

Thanks for the detailed guide. I installed plantation shutters last month and couldn't be happier with the results!
