Surface

There are four main types of court surface, each different in the speed and bounce of the ball:

Name	Description
Clay	Examples are red clay (used at the French Open and many other tournaments, especially in Europe and Latin America) and green clay (an example of which is Har-Tru and used mainly in the U.S.). Clay courts normally have a slower paced ball and a fairly true bounce with more spin.
Hard	Examples are acrylic (e.g. Plexicushion used at the Australian Open, DecoTurf used at the US Open), asphalt, and concrete. Hardcourts typically have a faster-paced ball with a very true bounce.
Grass	Used at Wimbledon. Grass courts usually have a faster-paced ball, and a more erratic bounce. Wimbledon has slowed its courts over the years. (see the cited main article, Grass courts).
Indoor	Examples are carpet and very rarely, wood. Carpet courts typically have a very fast-paced ball with a true but low bounce.
