Clay court

A tennis court surfaced with loose granular material, usually crushed brick or stone. Its high friction and soft footing slow the ball and shape how players move.

Court surface: The material layer on which a sport is played. Clay is one of tennis’s major court-surface types.
Baseline play: A tennis style centered on exchanging groundstrokes from near the back of the court. Long rallies and time to recover often reward sustained baseline play on clay.
Grass court: A tennis court surfaced with living or synthetic grass. Grass generally produces faster, lower bounces than clay.
Roland-Garros: A tennis complex in Paris that hosts the French Open. Its red clay courts are among the sport’s most recognizable examples.
Friction: The force that resists sliding between surfaces in contact. Clay’s friction affects how the ball grips and how players slide.
Topspin: A ball rotation that makes a shot dip sharply and bounce forward. Clay’s high bounce lets topspin-heavy shots push opponents back.
Hard court: A tennis court surfaced with a rigid layer, commonly asphalt or concrete beneath acrylic coating. Hard courts offer a firmer, more predictable bounce than loose clay.
Har-Tru: A green tennis-court surface made from crushed metabasalt, used mainly in North America. It is a prominent clay-like alternative to traditional red brick courts.
Coefficient of restitution: A measure of how much kinetic energy remains after two objects collide. Ball-surface collisions help determine the bounce’s speed and height.
Rally (tennis): A sequence of shots exchanged after a serve until a point ends. Slower shots often extend clay-court rallies.
