The first thing you should do is decide what type of curtains you are going to go for. At La Casa De Las Cortinas we have incredible styles from COLLECTION 2019 IN 2X1 in NOVEMBER.
Everything will depend on the type of decoration of your home, and how practical you want it to be. They are usually placed about four inches above the edges of the window, but they can be either lower or higher, depending on what you want and the room you have.
The next step is to decide how much you want to cover. Measure from frame to frame horizontally. It is advisable to leave additional four inches to each side (as long as there is room). On top measure in the same way. In the case of curtains, measure from the floor to the top frame. Another point to consider, too, is how much light you want to block.
Using a measuring tape, multiply the width by two so you can have curtains that have generous folds and look good in your environments.
