  • You would like us to make the manufacturers recommended deductions so that the blind fits within this recess perfectly.

Recess size

If you intend to hang your blinds within the window recess (sometimes called the reveal), you should measure the "recess size" which is the exact width and drop of the window recess. You should follow the instructions below.

  1. Measure the width of the recess from wall to wall in 3 places. Note down the shortest measurement.
  2. Measure the drop from the top of the recess to the window sill in 3 places. Note down the shortest measurement - this is the one you should use.

When you enter your measurements, select size type as "recess size". Do not make a deduction! As you have given us the exact dimensions of the recess, we will make the necessary deductions so that your blind will fit perfectly into the recess.

Frequently Asked Questions

What does recess mean in blinds?

In layman’s terms, the recess is the hole in the wall into which the window is fitted. You would generally install your blinds inside of the recess. You may also install your blinds outside of the recess, face fixing them to the wall surface. Inside recess installation is the most common method of blind installation.

How do I fit blinds to uPVC windows without drilling?

To fit blinds to UPVC windows without drilling, you can install Grip Fit blinds within your window recess or use clip fix mounting brackets to mount directly to the window. No drill blinds are a popular option for renters or homeowners who want to avoid drilling holes in their walls or windows. A Grip Fit blind is inserted into the top of the window recess and expands to create a tight fit. Clip fix mounting brackets, such as those used by Perfect Fit or INTU blinds, are inserted under the window beading.

How do I go about measuring my window recess for a blind?

Measuring your window recess for a blind is a straightforward process. Start by ensuring you have a reliable tape measure. Measure the width at the top, middle, and bottom of the window recess, always using the smallest measurement for the perfect fit. Measure the drop (length) at the left, centre, and right, again using the smallest measurement. Please remember to check for any obstructions in the window that may interfere with the fitting like handles or tiles. If you are planning to install blinds for French doors as well, the procedure is the same, again still keeping in mind any obstructions like door handles and skirting. Our website offers easy-to-follow step-by-step guides to ensure you get the best measurements possible.

How do I go about measuring my window recess for a blind, specifically for electric honeycomb blinds?

1) Measure the width in three places - at the top, middle, and bottom. Write down the shortest measurement, this is your recess width. - Be sure to ensure tiles or skirting is taken into account.

2) Measure the drop (height) in three places- at the left, middle, and right. Record the shortest measurement as your recess drop.

What do recess and exact mean on blinds?

Recess size is where you measure the width and height, inside of the window opening but in front of the window frame itself, from side to side and top to window sill. To ensure a perfect fit, when you submit recess size, a manufacturer would generally make a small deduction to the recess size. The exact size is where the customer knows the exact blind width and drop that they wish for the blind to be including all hardware/brackets. When the exact size is submitted, the manufacturer will not make any deductions. 

How far into recess to fit blinds?

Where you position your blinds within the depth of the recess will depend on a few things. Firstly, the depth, from front to back, of the recess. Secondly, any obstructions within the recess that would make any that depth unusable - this might include window hardware, such as handles or inward opening window panes. You should position the blind forward of these obstructions. You should also consider the remaining recess depth from the obstruction to the edge of the window recess, and whether the blind can be accommodate within this remaining space. If not, then you should consider face-fixing the blind outside of the recess.

If the blind can be accommodated, then really the final positioning of the recess fitted blind is down to aesthetics and light exclusion. You may personally feel that the blind looks better flush with the edge of the recess, or perhaps set back a little. For roller blinds, the closer you can position the blind to the window itself, the less light ingress you will see around the edges of the fabric. 

What is full recess depth?

When installing a blind within a recess, the full recess depth is the distance from the window itself to the front edge of the recess. Please note, the full recess depth might not be fully usable due to obstructions such as window handles, vents or inward opening panels. Where this is the case, it is important to check the remaining usable recess depth versus the front to back dimension of the blind itself to ensure that there is sufficient space to install the blind within the recess. 

Should blinds be fitted inside or outside the recess?

Normally blinds are inside-mounted. Blinds fitted within the recess look neater and maximise the room space. However, there are several cases where it might be better to install your blind outside of the recess.

Firstly, if there is not enough usable space within the recess to accommodate the blind.

Secondly, if you wish to keep your window sill free to display ornaments, flowers or pictures for example.

Thirdly, if your blind is a secondary window dressing - for example, if you already have a wooden Venetian blind fitted within the recess for privacy and day-time light control, you may wish to install a roman blind outside of the recess as a decorative soft furnishing that also provides blackout.

Finally, if you are looking to exclude light and increase privacy, then installation of blinds outside of the recess may be the best option because it allows the fabric to overlap the recess edges. This outside recess installation with ‘overlap’ is most common with roller blinds and Roman blinds. 

What does recess fit mean?

When a blind is recess fitted, it is installed within the opening in the wall which contains the window. This is often done to keep the blind from dominating the room space and also can make the room look brighter, more organised and spacious and neatly put together. 

What does recess mean when ordering a blind?

When you order a recess blind, the manufacturer will make any necessary deductions so that the blind will fit inside the window recess. The recess is the ‘hole in the wall’ in which your window is installed. Usually, there will be plasterwork at the left, right and top, and a window sill finishing the bottom of the recess. If you intend to recess fit your blind, then measure the recess width and drop and select ‘recess size’ when submitting your sizes. The manufacturer will make any necessary deductions without you having to make any additional calculations.

Should blinds be recessed or not?

Fitting blinds inside the recess is preferred by many who want a neater, brighter and more spacious appearance. However, if there is not enough space in your recess to mount the blind, due to opening panes, window handles, ornaments or other decorative items, or if you wish your blind to overlap the recess edges to provide more blackout, then the alternative is to mount the blind outside of the recess.

What is the difference between recess fit and exact fit for blinds?

The distinction between exact and recess-fit blinds revolves around how the blinds are fitted in relation to the window recess:

Recess Fit Blinds:

  • Recess-fit blinds are installed within the window recess.
  • They are typically sized to fit within the window recess, filling the entire window area, less a small deduction
  • When you order a recess fit blind, you do not need to make any adjustments to the sizes - the manufacturer will make small deductions

Exact Fit Blinds:

  • Exact-fit blinds, on the other hand, are generally fitted outside the window recess.
  • They are attached to the wall above the window, covering both the window recess and a portion of the wall on either side of the recess​.
  • This fitting style is commonly referred to as an exact fitting​.
  • You may also wish to submit exact sizes in any situation where you would like the blind manufactured to your exact sizes and do not want the manufacturer to make any deductions.
