How to Measure Pleated Blinds?

Why accuracy matters for pleated blinds

Pleated blinds bring a soft, elegant finish to any window – but their neat folds only look right when the measurements are spot on. Too tight and the blind won’t glide properly; too loose and you’ll get gaps at the edges. Taking precise measurements at the start ensures a polished look and smooth operation.

Tools you’ll want nearby

Before you begin, grab:

  • A sturdy metal tape measure (for accurate readings)
  • A pencil for quick notes
  • A notepad or paper to record your numbers
  • A step stool if the window is tall or awkward to reach

Inside or outside the recess – your choice

Your first step is deciding whether you want your pleated blind to fit:

  • Inside the recess (recess fit): The blind sits snugly within the window space for a clean, minimal look.
  • Outside the recess (exact fit): The blind is mounted over the opening, overlapping the wall or frame – ideal if you’d like to block more light or cover an uneven recess.

The style you choose will affect how you measure.

Step-by-step instructions for measuring

Measuring the width

  • Recess fit: Measure across the inside width of the recess at three points – top, middle, and bottom. Note all three and use the smallest measurement.
  • Exact fit: Measure the width of the window opening and add an overlap (usually 7–10cm on each side) to reduce light gaps.

Measuring the drop

  • Recess fit: Measure the inside height of the recess in three places – left, centre, and right. Record all three and use the shortest measurement.
  • Exact fit: Measure from where you’d like the top of the blind to sit down to your preferred finishing point. Add extra if you’d like fuller coverage.

Double-check your results

It’s easy to misread or mix up numbers, so always go over your figures again. The rule of thumb is simple: measure twice, cut once.

Mistakes to avoid

Here are some common errors worth steering clear of:

  • Measuring only once instead of three times
  • Forgetting to allow for obstructions such as handles, tiles, or radiators
  • Using a fabric or flexible tape that may bend or stretch
  • Rounding up or down instead of writing figures exactly as they are

FAQ – How to Measure Pleated Blinds?

Do I measure in centimetres or millimetres?

Centimetres are fine, but it’s best to note figures down to the nearest millimetre for maximum accuracy.

How much extra should I add for an outside fit?

Adding around 7–10cm on each side of the window is usually enough to block light effectively.

Should I measure every window, even if they look the same?

Yes – no two windows are exactly alike, so measure each one individually for the best results.
