Step 1: Decide How You Want the Blinds to Fit

Option A – Inside Recess Fit

Blinds sit neatly inside the window frame (recess), ideal for a clean, built-in look.
Best for windows with deep recesses and no obstructions.

• Width: Measure the width of the recess in three places – top, middle, and bottom. Use the narrowest measurement to ensure the blind fits properly.
• Extra tip: If you want your blinds to go all the way down to the floor, measure the width between the skirting boards at the bottom — this is often the narrowest point.
• Drop (height): Measure from the top of the recess to the windowsill or floor, again in three places. Use the shortest measurement.

Option B – Outside Recess Fit

Blinds are mounted outside the window frame, covering the wall or overlapping the recess.

Great for full light block, shallow recesses, or uneven frames.

Every single window dressing we create is treated as a bespoke and professional project.

Step 2: Measuring for Inside Recess Fit

• Width: Measure the width of the recess in three places – top, middle, and bottom.
  Use the narrowest measurement (to ensure the blind fits inside).
• Drop (height): Measure from the top of the recess to the windowsill or floor, again in three places.
  Use the shortest measurement.

Tip：We will make a small deduction to ensure a smooth fit inside the recess – you don’t need to adjust your measurements.

Step 3: Measuring for Outside Recess Fit

• Width: Measure the width of the window and add 10–20cm on each side to ensure full coverage.
• Drop (height): Measure from where you plan to mount the blind (above the window) to where you want it to end (e.g. sill or floor).

• • Usually mount at least 10cm above the window for better light control.

Tools You’ll Need

• Metal tape measure
• Notebook or phone to record measurements
• Pencil for marking positions if needed

Tips

• Always measure in centimetres (cm)
• Double-check every measurement
• For Roman blinds, ensure there’s space above the window for the blind to stack when raised
