Start by taking measurements of your window, so you can choose curtains. A good rule of thumb is to get curtain panels that are twice the width of your window or even slightly larger, so you get luxurious folds when they’re hanging and full coverage when they’re closed.
The curtain length you choose depends on how high you’ll be hanging your curtain rod and how close to the floor you prefer your curtains to be. A good rule of thumb is 4 to 6 inches above the window frame, but to make a room feel taller, hang them closer to the ceiling, up to 12 inches above the window frame. For a clean, casual look, choose a length that falls half-an-inch above the floor. For a more luxurious puddle effect, choose curtains that are 6 to 8 inches longer than the rod to floor measurement.
Don’t forget, the header of the curtains will factor into height measurements. Rod pockets will hang shorter than grommets or tab tops.
Choose a rod
Rods should be 6 to 12 inches wider than your window, so your curtains don’t cover any of your view when they’re open. Single rods allow you to hang just a curtain or sheer panels. Double rods allow you to hang both a curtain and sheer panels.
Create a right angle template
Using cardboard, create a simple right-angle template to mark your bracket spot, to ensure that your rods won’t be crooked. Remember that your bracket should be 4 to 6 inches above the window frame and 3 to 6 inches outside the frame on each side. Save time and use this template throughout your home, so all your curtains will be hung at the same height.
Mark your bracket spots
Using a pencil and your right-angle template, mark your bracket spot on each side.
Install the brackets
Following your rod instructions, attach the brackets to the wall. If your rod is longer than four feet, add a third bracket in the centre to avoid having your rod bow in the middle.
Test the rod with a level
Put the rod up and place a level on the top of it to check the everything is even and balanced.
Hang your curtains on the rod. Centre the rod and then tighten the set screws on the brackets to hold it in place.
