How to Measure for Blinds on a Bay Window

Measuring bay windows for made to measure blinds can seem daunting, but with a few simple steps, it can be done easily. When measuring bay windows for blinds, it’s important to take accurate measurements to ensure a perfect fit. Follow the relevant guide for you below or if you’d rather we measured up for you, book in a measuring appointment.

You will need:

  • a metal tape measure
  • a pen or pencil
  • a piece of paper

Measuring the Width

STEP 01.

Take 2 pieces of card with a straight edge (you can use the information cards in your sample pack). Mark a line with a pencil parallel to the long edge: 5cm for ROMAN BLINDS or 7cm for ROLLER BLINDS

STEP 02.

Hold the cards in one hand against the wall at the height you will install the blinds so that the lines you’ve drawn touch. Mark where the front edges of the card touch the wall

STEP 03.

Measure the side windows from the outer edge of the window frame to the mark you made, and the centre window between the two marks. Measure the height and installation height as same for roman + rollers in outside recess

Measuring the Height


For each window measure the height from where you would like to install your blind to the window sill (or bottom of the recess). We recommend installing your blind up to 30cm above the window frame.


For each window measure the height at which you will install the blind to the floor. This is so we can make sure your pull chain is the correct height.

Frequently Asked Questions

How to fit my blinds?

Our roman blinds can be screwed into your wall or onto your ceiling using the bracket provided. Simply install the brackets and clip your blind into place. Similarly, for our roller blinds, clip your blinds into the brackets by placing the spring-loaded pin in the hole and hook the chain end into the cross.

Young children sometimes find roman and roller blind chains fun to play with. To avoid children putting their heads through the loop of your roman or roller blind chain:

Keep cords out of reach Make sure beds, cots and other furniture are moved away from where the chain hangs Install the chain tensioning clip supplied with your blind to make sure that your chain is child safe.

Do blinds have seams or joins?

The possible width of a fabric comes from the width of the roll. If your windows are wider than the fabric width then it is necessary to have a vertical join to cover the entire window. We place the largest possible width in the centre of the blind and add additional fabric width on either side. This way the seam or join is closer to the edge and less noticeable.

How long do made to measure blinds take?

Our made-to-measure blinds are hand stitched to your bespoke requirements, every detail finished by hand in local workshops up and down the country.
