When taking measurements, be sure to measure from the top of the window to the place where you want them to end. This will ensure that they are the right size. If you are hanging them for decorative purposes, they should hardly stick to the floor. If they are too tall, they will look crooked. If they're too small, it'll look like you've made a mistake.
For functional purposes, such as blocking light or providing privacy, make sure they are long enough to cover the entire window. Additionally, do not forget to take into account the width of the rod when measuring the width. You won't want your curtains to be too comfortable or too loose.
Finally, be sure to use proper hardware when hanging curtains. Whenever possible, rods should be mounted in wall studs for added stability. If you're hanging heavy clothes, be sure to use brackets that can support the weight. With the right tools and a little planning, you can hang them like a professional!
