This guide works for:
Vertical blinds

Step 1 - Measuring the width

First measure the width from corner to corner on both the sides and the front of the box bay.


You need to then make deductions to create allowance for the other blinds to prevent the fabric slats hitting each other.

Your bracket will be 75mm which allows a clearance of approx. 25mm between the fabric and the facing surface.

  • Reduce the width measurement for the side blinds by the size of one bracket = 75mm
  • Reduce the width measurement for the front blind by the size of two bracket = 2 x 75mm = 150mm

Step 2 - Measuring the drop

The drop can be measured as normal – again in three places. Be aware of how you are fitting the blinds so you know where the top is to measure down from. We recommend you reduce this measurement by 15mm to give clearance from the window sill – it stops the fabric slats from dragging.

Once you have noted your measurements, enter the sizes into www.Blinds4You.co.uk/xxxxxxxxx and choose the Exact fitting option. We will make your new blind to your sizes without deductions and send them out to you ready to fit.
