When measuring for blinds, you don’t need a full toolbox. A metal tape measure, pencil and a notepad will be everything you need to get the job done. Get started on your recess fit and record the width with your tape measure, taking down the measurements in your notepad.
Measure the width at the top of the recess, the middle, and the bottom to identify any variations. Then use the smallest measurement of the three when ordering your blind to make sure it fits perfectly.
Follow the same approach for the length of the blind, taking measurements at three different points along the window recess - left, middle and right - and provide us with the shortest one. This is commonly known as the recess drop measurement, as it's the length the blind needs to drop when extended – but it still has to be long enough to cover the entire window.
If you have a window recess, you can still decide to fit the blinds on the outside. Let's look at how to do that in this next section.
Measuring for blinds without a recess or outside a recess is a simple process. Find the width of your window frame or recess and add an extra 120mm to the overall measurement, so that there’s 60mm overlap on either side. This will ensure your entire window is covered by the blind.
The next step is measuring the drop of the blind, taking into consideration how far down you want the blind to go when fully extended. As with a recess fit, simply measure from the top of the fitting to where the blind will drop to, taking into consideration any objects such as radiators that may obstruct your window dressing.
Ideally the blind should not obscure the window when it is raised so you may want to consider adding overlap at the top and/or bottom. Like with the width, we suggest adding 60mm to the top and bottom (120mm total) so that there is some overlap on the length.
We recommend taking your width and drop measurements in 3 different places, as windows are not always perfectly square, and provide the largest measurement to ensure the best fit.
When measuring for these blind types, with a recess fitting, please take the width measurement across the top of the window to ensure the best fit.
Please note, whether you order recess or exact fitting, the fabric width will always be 35-40mm narrower than the overall size. This is to allow for any control component on the side. We will always take the provided width and manufacture this as the full blind width (not fabric width). If you are wishing to fit one of these blinds outside the recess, you may want to consider measuring wider and allowing some overlap of fabric.
If you are ordering a roller blind to fit inside a recess and wish to side mount the brackets, please provide the measurement across the top of the window and select exact instead of recess (Day Night, Vista and Harmony blinds cannot be side mounted).
When you’re measuring your blinds you will also need to consider things like the type of windows you have and the different blinds you may want to fit. We can help you adjust your measuring technique for the perfect fit.
If you have bay windows, for example, they may require a more specific fitting. There are different designs of bay window, such as a square bay, open, splay bay or angled bay, so you will need to be very specific with the size of the blinds you’re measuring for. You can visit our Bay Window guide here.
You will also need to take into account whether your window is suited to a blind, and think about any potential obstructions that may add to the width of your blind brackets. This includes air vents, window handles, locks or anything else that sticks out from the window.
The following table is a guide to the amount we will deduct if you select ‘recess’ measurement. We make these deductions to enable the blind to fit inside your recess so it is important to be precise with your measurements. If you wish to make your own allowances instead and do not require us to make them, please select exact fitting and not recess.
