Measuring tips

• It is best to use a metal tape measure and have some paper handy to write down your measurements straight away.
• Look out for window handles and the positioning of tiles at the top and bottom of your window. You should also think about how your window opens. Take measurements from an area that is in front of your window handles so the blind will move up and down when you fit it here.
• Don't forget we are just on the end of the phone, any questions please call 0845 604 9610 or e-mail enquiries@blinds-supermarket.co.uk

All orders should be entered with measurements in cm's to the nearest 0.1cm. If you decide to measure in inches please use our measurement converter.

Before you do any measuring you'll need to decide if you want your blind to sit inside the window recess or hang outside.

For a neat fit that blocks out the light choose to fit your blinds inside the recess. For windows that aren’t straight or have lots of obstructions choose to fit your blinds outside the recess.

Blinds inside the recess - Recess measurement

If you choose to fit inside the recess, choosing the recess option when ordering your blinds, the blind will be made to fit perfectly inside your window. Just follow the simple steps below:

1. Measure the width of the recess from wall to wall in three places as shown. Write down the shortest measurement - this is the one we'll use.
2. Measure the drop by taking the measurement from the top of the recess to the windowsill in three places as shown. Write down the shortest measurement.
3. Choose your fabric and place your order!

All recess blinds are reduced by our factory to take into account the size of the headrail and components to ensure a perfect fit. Please do not make any adjustments to your measurements we do this for you. Below is a guide of the reductions we will make when we receive your order.

• Vertical blinds = approximately 1cm width, and 5cm off louvres. (4cm for Headrail height and 1cm for the gap between louvre and windowsill/floor.)
• Venetian blinds = approximately 1cm in width
• Wood Venetian blinds = approximately 1cm in width
• Roller blinds = approximately 1cm in width and 3.3cm from the actual fabric
• Roman blinds = approximately 1cm in width
• Woodweave blinds = approximately 2cm in width
• Thermal blinds = approximately 1cm in width

Blinds outside the recess - Exact measurements

If you choose to fit outside the recess, choosing the exact option when ordering your blind, the blind will be made to your exact measurements. Just follow the simple steps below:

1. Measure the width of where you'd like your blind to be.
2. Measure the length from the top of where you want your blind to be to the bottom. This is the drop measurement.
3. Choose your fabric and place your order!

Important Note for Roller Blinds - When ordering an EXACT roller blind the actual fabric will be made approximately 2.8cm less in width due to the headrail. If you would like your EXACT width measurement to be your actual fabric width, you will need to add 2.8cm to the measurement

Important Note for Vertical Blinds - When ordering EXACT vertical blinds the width you order will be EXACT but the drop will be approximately 1cm less as we take 5cm off our louvres (4cm for Headrail height and 1cm for the gap between louvre and windowsill/floor.)
