Curtains are fabric panels used to cover windows, and are generally cut to fit a window or drop a few centimetres below it. Drapes are also fabric panels but are generally made from thicker fabrics and cut to floor length or to slightly puddle on the floor.

In interior design, drapery refers almost exclusively to window treatments. It is often used as a focal point alongside the windows or as a way to help block sun/glare.
