The most popular choice, and easiest to install, are the tension or spring rods. No hardware is needed because when placed between the window mouldings they hold themselves up due to the springs in the rod. These work best for kitchen and bathroom curtains and are usually purchased in either white or brass.

Another type of curtain rod is the magnetic rod, which is very similar to the spring rod in that it holds itself up within the window mouldings. However, they are more expensive and do require metal sills and mouldings. Some people who purchase magnetic rods, choose to glue the rods up.

A third type of curtain rod is the sash rod. These are screwed directly into the window frame and are intended to be slightly above and right next to the window frame. For this reason, you will need to purchase curtains that are slightly longer than the window. Many people use these curtain rods for longer living room and dining room curtains.

A fourth type of curtain rod is the cafe sash rod. These are very similar to sash rods, but not as thin. Unlike the sash rods, they are meant to stick out from the window some. These, as well as sash rods, are available in a variety of colors.

A final of the types of curtain rods are specialty rods. These can be found in several different styles for special shaped windows. Some can swing out and are usually used for glass doors. These are more expensive and usually specially ordered.
