Measuring for Cassette Roller Blinds

Standard Window

Choose your fit

For a standard window there are multiple fitting options available to cater for varying window spaces.

Please choose one of the options below

  • Option 1: Inside Recess

    To install your roller blind within your window recess, follow the steps below. Recommended

  • Option 2: Exact Size

    If you know your exact width and drop requirements, follow the steps below. When selecting the "Box Size" fitting option, we will supply the blind cassette exactly to your width measurement provided.

  • Option 3: Split Window

    To use multiple blinds to span a single window, follow the steps below. This is an excellent choice for large windows or windows with a clear split.

Step 1 - Width Measurement

Step 1 - Width Measurement

Measure the width of the recess in at least three places where you would like to install your blind. You will use the smallest of these figures as your width measurement when ordering your blind.

Important!

Check your depth – To allow sufficient room for your blind to operate, it’s important that there is a minimum of 85mm depth clearance (if you are top-fixing the brackets) or 95mm depth clearance (if you are face-fixing the brackets) between the farthest point of any obstruction and the front of the recess.

Check for any width obstructions – Any obstructions in your recess (tiles, etc.) may reduce its effective width. Find the effective width by measuring between these points. If your top recess measurement is at least 40mm greater than this figure, then use the effective width figure when ordering your blind. Otherwise, use the top recess measurement as your width measurement as explained above. (For example: if the bottom of your recess measures 970mm and the top measures 1000mm, you would enter your top width measurement as the fabric width would clear the obstruction. This is because the top recess measurement is only 30mm (less than 40mm) greater than the bottom measurement.)

Please note: The fabric, including the bottom bar, will be approximately 48mm narrower than the recess measurement provided.

Step 2 – Drop Measurement

Step 2 – Drop Measurement

Measure the height of the recess. You will use this figure as your drop measurement when ordering your blinds.

Step 3 – Recess Fitting Option

Step 3 – Recess Fitting Option

Select the “Recess” fitting option when you order each blind for your window. This lets us know to adjust the measurement to make room for the appropriate brackets.

Step 1 - Width Measurement

Step 1 - Width Measurement

First determine how far you want your cassette to overlap your window recess on each side. Make sure to include this overlap when measuring your width.

Important!

Overlap – We suggest an overlap of at least 100mm on either side of the window recess. This means including an extra 200mm in your width measurement (in addition to the width of the recess). Top tip: check for any obstructions, such as light switches, to ensure that no objects conflict with the blind overlap.

Improved light exclusion – The greater the overlap, the more effective your blinds will be in eliminating light from outside.

Please note the width of the fabric will be approx 39mm less than the Box Size measurement provided.

Step 2 - Drop Measurement

Step 2 - Drop Measurement

First determine where you’d like your headrail and bottom bar to be positioned. Measure the distance between these two heights and use this figure as your drop value when ordering your blinds.

Important!

Overlap (top) – We suggest an overlap of at least 100mm beyond the top of the window recess.

Overlap (bottom) – Top tip: Obstructions, such as a radiator, may limit your bottom overlap. If the window sill protrudes by over 50mm, the bottom of your blind should be placed at this point. Otherwise, the amount of bottom overlap is a matter of personal taste.

Step 3 – Box Size Fitting Option

Step 3 – Box Size Fitting Option

Select the “Box Size” fitting option when ordering your blind for your window. Please note the width of the fabric will be approx 39mm less than the Box Size measurement provided.

Step 1 – Split Point

Step 1 – Split Point

Decide where you’d like to split your blinds. Mark this point using a pencil.

Useful Suggestions

Choosing your split point – The centre of the window is often the natural split point. However, a different split point may be chosen to accommodate a mullion or window/door frame.

Important note – To make room for the brackets, there will be a small gap between each cassette box. Remember, this will then mean you will have at least 48mm - 53mm between the fabric sections.

Step 2 – Width Measurements

Step 2 – Width Measurements

If installing within the window recess, measure the distance between your split point and the edge of the recess. Use this figure as your width measurement when ordering your blind.

Important!

Outside your recess – If you're installing your roller blinds in front of your recess, rather than inside it, measure between the split point and the place you’d like your blind to finish.

Check your depth – To allow sufficient room for your blind to operate, it’s important that there is a minimum of 85mm depth clearance (if you are top-fixing the brackets) or 95mm depth clearance (if you are face-fixing the brackets) between the farthest point of any obstruction and the front of the recess.

Check for any width obstructions – Any obstructions in your recess (tiles, etc.) may reduce its effective width. Find the effective width by measuring between these points. If your top recess measurement is at least 40mm greater than this figure, then use the effective width figure when ordering your blind. Otherwise, use the top recess measurement as your width measurement as explained above. (For example: if the bottom of your recess measures 970mm and the top measures 1000mm, you would enter your top width measurement as the fabric width would clear the obstruction. This is because the top recess measurement is only 30mm (less than 40mm) greater than the bottom measurement.)

Mind the gap – To make room for the brackets within your window recess, your split blinds will have a small gap at the top (around 5mm), determined by the distance between the central brackets. This will create a gap of at least 48mm - 53mm between the adjacent fabric sections.

Step 3 – Drop Measurements

Step 3 – Drop Measurements

Measure the height of the recess in at least three places where you would like to install your blinds. You will use the smallest of these figures as your drop measurement when ordering your blinds.

Important!

Outside your recess – If you're installing your blinds in front of your recess, rather than inside it, measure between where you would like to place the top and bottom of your blinds.

Check for any drop obstructions – We suggest an overlap of at least 100mm beyond the top of the window recess.

Overlap (bottom) – Top tip: Obstructions, such as a radiator, may limit your bottom overlap. If the window sill protrudes by over 50mm, the bottom of your blind should be placed at this point. Otherwise, the amount of bottom overlap is a matter of personal taste.

Step 4 – Recess Fitting Option

Final step

If your blinds will lie within the recess, select the “Recess” fitting option; if your blinds will sit outside the recess, select the “Box Size” fitting option. This lets us know to adjust the measurement to make room for the appropriate brackets.
