Clay courts are more common in Continental Europe and Latin America than in the United States, Canada or Britain. In the United States, courts made of green clay, also known as "rubico", are often called "clay", but are not made of the same clay used in most European and Latin American countries. Although cheaper to construct than other types of tennis courts, the maintenance

 costs of clay are high as the surface must be rolled to preserve flatness. The water content must also be balanced; green courts are often sloped in order to allow water run-off.

Clay courts are considered "slow", because the balls bounce relatively high and more slowly, making it more difficult for a player to hit an unreturnable shot. Points

s to throw off their opponents. Movement on gravel courts is very different from movement on any other surface. Playing on clay often involves the ability to slide into the ball during the stroke, as opposed to running and stopping like on a hard or grass court. Players who excel on clay courts but struggle to replicate the same form on fast courts are known as clay-court specialists.

Clay courts are unique in that the ball bounce leaves an impression in the ground, which can help determine whether a shot was in or out. Critics of red clay courts point to the constant need to wet them down, problems renewing the surface if it dries out, and the damage caused to clothing and footwear through stains.

Red clay

Almost all red "clay" courts are made not of natural clay but of crushed brick that is packed to make the court. The crushed brick is then covered with a topping of other crushed particles. This type of surface does not absorb water easily and is the most common in Europe and Latin America. True natural clay courts are rare because they take two to three days to dry. A good example of natural red clay can be seen at the Frick Park Clay Courts in Pittsburgh, PA, a public facility of six red clay courts that has been in continual use since 1930.

Green clay

Green clay, Har-Tru or "American" clay, is similar to red clay, the differences being that it is slightly harder and faster. Green clay is packed to make the subsurface. It is then covered with a topping. These clay courts can be found in all 50 of the United States but are located primarily in the Eastern and Southern states. In parts of the gulf coast region of the Southeast, green clay courts are often referred to as "rubico". There is one WTA
