Our guide to installing a roller blind

Terry Baskeyfield | Updated

Installing a roller blind is a relatively simple procedure. With the right tools and allowing sufficient time so that you aren't rushed your roller blind will be at your windows and usable in no time at all. Roller blinds are a sleek, discreet window dressing that is ideal as a sole window dressing or can be used in combination with curtains or drapes. An extensive variety of colours and designs means there is a roller blind to suit most decorating motifs beautifully. This guide explains how to fit a roller blind inside or outside the window recess.

Measuring For Window Blinds


Clear the window area, including the window sill. Use dust cloths to help protect the sill and floor.

Tools required

• Step ladder • Tape measure • Raw plugs • Screws • Pencil • Drill • Drill bits

The roller blind will come with two different brackets, one for the control side, the other for the spring loaded side. A child safety mechanism, which attaches to the wall, will also be included.

Inside installation

Fitting the roller blind inside the recess of the window gives you three fixing options, top, side or face fix. The recess must also be a minimum 75 cm deep to house the operating mechanism. Fitting the blind inside the recess of the window does restrict the amount of light entering the room due to the depth of the mechanism, however, the little amount of lost light is compensated with unrestricted views to the outside for the majority of the window.

Top fix

In this method you secure the brackets to the ceiling of the recess. Check to see whether the lintel is metal or concrete to ensure you use the correct type of drill bit. There is a possibility that you could be drilling into wood, so take time to check before you start drilling. Hold the brackets flat against the ceiling and using the pencil mark where the screw holes are. Drill the holes, and then gently tap in the raw plugs before securely fix the brackets into place using the screws. Fit the roller blind into the two brackets. Secure the child safety mechanism onto the side of the window recess.

Face fix

In this fixing method you drill into the window frame itself. Be aware that with a face fix you will be left with screw holes in the frame; this may invalidate a guarantee, particularly on PVC windows, so check the warranty before you start. Use the same method above to mark and fix the brackets and fit the blind. Fix the child safety mechanism to the side of the frame.

Side fix

This method should only be used if you are unable to use one of the previous two methods. Check prior to fixing the brackets that you have made sufficient allowance for any protruding handles, as the blind will need to clear these to roll down properly. To ensure the roller blind fits tightly, to prevent it jumping out of the spring loaded bracket, the brackets should be stepped in by 0.5 cm. Use the same method above to mark and fix the brackets and fit the blind. Fix the child safety mechanism to the side of the frame.

Child safety mechanism

Fit the child safety mechanism on the same side as the chain falls. the height of the mechanism will be controlled by the chain and requires the tension of the chain to be taught at all times.

External installation

If you want an external fix you only have the face fix option. Be careful not to drill to close to the bottom edge of the recess as this can cause the wall plaster to crack, resulting in an unstable fix. The child safety mechanism will also be fixed to the wall. This style of fitting does not restrict any natural light entering the room. By placing the roller blind higher than the recess you can give the window the illusion of higher, taller windows. Likewise, buying roller blinds wider that the actual size of the window will give the illusion of wider windows.

Ready made roller blinds

Ready made roller blinds are designed for you to cut or trim them to fit the size of your window. Always buy a ready made roller blind that is larger than your window, unless you are very lucky and have windows exactly the right size. This is often the case when using an external fix but rarely for an internal fix. To trim a roller blind to size you will need to completely unroll the fabric onto a flat surface. Use a straight edge to make a pencil line at the desired width. Use sharp scissors to cut the fabric on the marked line and a hacksaw to cut the header rail to the same size. Ready made roller blinds come with fitting instructions to follow.

Made to measure roller blinds

Made to measure roller blinds make life a whole lot easier! There will be no need to cut the fabric or the header rail, all you have to do it fix the two brackets and the child safety mechanism and the blind is ready to use.
