Recess vs Exact

Your windows will most likely be recessed into the walls which means they don't sit flush with your wallpaper. This gives you the choice to mount them inside (Recess fitting) or outside (Exact fitting) the recess.

If you're lucky enough to have windows that sit flush, the choice is made for you and you'll be measuring for Exact fitting.


How do you want the blind to sit against your window?

If your recess depth is 60mm or less or the window opens inwards, you'll be best off with an exact fitting. To do this please follow the measuring guide for exact fitting blinds


If the bottom part of your recess is tiled (often the case in bathrooms and kitchens) take your width measurement from the tiled part of the recess, as this will be the narrowest part

247 Pro Tips:

For the best results allow your blind to overlap the edges of the recess by at least 35mm on each side - ensuring that you have enough space to accommodate the suggested overlap.


Please note: exact measurements are not the just the width of the fabric or material alone, but also include headrail fittings and controls for Roller Blinds only.


Additional Information

Replacing an existing blind

When replacing a blind the same size already in your window it is really easy, just measure the full length of it including all controls and fittings normally across the very top and then from the top to the very bottom of the blind for the drop, then select exact when submitting your measurements.

Roller Blinds, Day Night Blinds, Vista Blinds and Double Roller Blinds

  • The fabric width on these blinds will be 35-40mm narrower than the overall width of the blind. This is to allow for any control component on the side of the tube (or 'cassette'). We will always manufacture the full blind width and not fabric width. If you are fitting one of these blinds outside the recess, you may want to consider measuring wider to allow for some fabric overlap.
  • The bottom rail is 1cm wider than the fabric at either side for both Day Night and Vista blinds. This is due to the end caps required to hold the rail in place.
  • When measuring for roller blinds inside a recess, please take the width measurement across the top of the window to ensure the best fit - even if you have tiling around the bottom, as the narrower fabric will fall between the average piece of tiling
  • If you are fitting a roller blind or double roller inside of a recess and wish to mount the brackets to the sides of the recess (opposed to the lintel or window frame), please make sure that you measure across the top of the recess and select 'exact' instead of 'recess' to allow this particular type of mounting (Note: day night blinds or vista blinds cannot be side mounted).

Bay Windows and Conservatories

  • There are different designs of bay window, such as a square or angled bay, so bay windows may require a more specific fitting as you need to take the brackets and mounting in to account. To ensure accurate measuring for bay windows, please consult our Bay Window Guide.
  • You can find our Conservatory Measuring Guide here. Please note that not all blind types may be suited to conservatories but we do provide a range of blinds specially designed for Conservatories.

How much we deduct for recess measurements

We try to make the measuring and ordering process as simple as possible - so for a recess fitting, we only require the full size of your recess space and we will then make small adjustments to the blind to enable it to fit within that space. The following table is a guide to the amount that we will deduct if you select a 'recess' fitting.

Please note that if you wish to make your own allowances and do not require us to make them, please select exact fitting and not recess during the order process.

Day Night Blinds 5 0
Double Roller Blinds 5 0
