How To Measure For A Venetian Blind

Measuring your windows to get your ideal blind size is not a difficult task, simply follow the 3 steps below. You can measure in centimeters, millimeters or inches, but please remember the more precise you are, the more precise we are.

This quick video shows you step-by-step how you can measure for Venetian Blinds, using the blindsbypost website.

We have also highlighted some key points to remember below.

- Measure in 3 places and always use the smallest measurements
- Don't make any deductions from your measured sizes
- Read and follow our guides before ordering

recess size

Measure For Recess

For a recess fitting blind please measure your window recess exactly. We always advise to measure the width and height of the recess in multiple places and quote the minimum values when ordering. We then make small deductions needed to ensure the blind fits perfectly into the recess.

Please Note: if the recess is less than 60mm / 2.5" deep, the window opens inwards or there are other obstructions the blind may have to be fitted outside the recess.

  1. Measure the width of your recess (wall to wall) in 3 different locations. The most important measurement to write down is the smallest one.
  2. Measure the drop (height) of your recess ( top to window sill) in 3 different locations. Once again the most important measurement to write down is the smallest one.
  3. Use these exact measurements throughout our website and ensure you select "Recess" as the measurement type

Please Note: if the recess is less than 60mm / 2.5" deep, the window opens inwards or there are other obstructions the blind may have to be fitted outside the recess

exact blind size

Measure Exact

Please use this measurement method for fitting blinds outside the recess or if we have already sent you brackets for your unique windows. We recommend a window recess overlap of at least 80mm on each side. This ensures complete coverage of the window. We do not make any deductions to the measurements given when using the actual blind size option.

  1. Measure the width of your window and any overlap you require. We advice an overlap of at least 6cm on the window recess.
  2. Measure the drop (height) of your window and any overlap you require. Once again we advice an overlap of at least 6cm on the window recess.
  3. Use these exact measurements throughout our website and ensure you select "Exact" as the measurement type.

Please note: the drop given will be the overall blind drop (from the top of the cassette rail to the bottom of the slats)

bracket to bracket size

Measure Bracket to Bracket

This is the measurement is designed for customers who have taken advantage of our bay window service.

  1. Measure the width from inside bracket to bracket
  2. Measure the drop required, either to the windowsill, or where you would like the blind to stop. This would need to be taken from the top of the bracket.
  3. Use these measurements throughout our website and ensure you select "Bracket to Bracket" as the measurement type.

Please note, we will make a small deduction on the width given to ensure the blind can slide smoothy into the fitted brackets
