How to Install a Curtain Rail

When choosing a curtain rail, bear in mind that you need a rail that is a minimum of 15-20cm longer than the width of the window on each side (total extra length: 30-40cm minimum) to allow the curtains to sit at each side of the window without obstructing the light. For example, if the window is 100cm wide you need a rail at least 130cm long.

Some longer curtain rails come in two pieces which you must join together before installation. The rails are generally pre-drilled to facilitate a double-sided screw coupler. This allows the ends of the rails to be firmly butted together at the centre.

Mount the necessary curtain rings onto the pole before screwing the end caps into place. The end caps are fitted using the same type of double-sided screw.

A curtain rail should be positioned approximately halfway between the top of the window and the ceiling. Using a measuring tape, mark the centre of the window by measuring the width of the window and dividing the measurement by two. Determine the position of the end support posts by measuring from the centre mark outwards. Then measure up from the floor to ensure all the posts occur at the same height. Mark the position of the post mounting holes. Longer poles may need a third bracket in the centre to hold the pole securely.

Before drilling into any wall, always check for wires or pipes behind the wall. This can be done with a multi-purpose detector. You should also determine what type of wall you are drilling into, this will help you know what drill bit and fixings to use. Drill the wall in the positions marked in step 4, insert suitable wall plugs and firmly screw the support brackets into place.

Attach the support posts to the post brackets and screw tightly.

Secure the rail into the support posts using a small screw underneath each bracket. This will stop the curtain rail from hopping off its brackets should the curtain rail be pulled roughly.
