Hard, clay or grass: how tennis court surfaces play

What a surface changes

Every surface comes down to two things: friction and bounce. Friction decides how much speed the ball keeps when it lands. A grippy, gritty surface slows it and lets spin bite. A smooth one lets it skid through. Bounce decides how high it sits up afterwards. Together they set the pace of a court, which the International Tennis Federation measures and sorts into five categories, from slow to fast.

A slow court gives you more time on every shot, rewards consistency and long rallies, and makes heavy topspin kick up high. A fast court rewards a big serve and flat, early hitting, and punishes a late swing. Neither is better. Most players simply have one they grew up on and one that feels foreign.

Hard courts

Most courts in the United States are hard courts: asphalt or concrete with an acrylic coating on top, painted in the familiar blue or green. Public parks, schools and most clubs have them because they are cheap to build, need little upkeep, and are playable as soon as the rain stops and the water is swept off. The US Open and the Australian Open are both played on acrylic hard courts.

The pace of a hard court depends on how much sand is mixed into the paint. More sand means more grip and a slower court, and as a court ages and the texture wears smooth it gets faster. That is why two public courts in the same town can feel different. Old, shiny ones play quick and skid; freshly resurfaced ones grab the ball.

What to expect

• A true bounce. The ball comes up where you expect it to, which makes hard courts the easiest place to learn timing.
• Hard on the body. There is no give underfoot and no sliding, so knees, hips and ankles take every stop. Cushioned acrylic systems soften this, but most public courts do not have them.
• Tough on shoes and balls. The abrasive surface wears soles and ball felt quickly. A can of balls that would last several sessions on clay can be flat and bald after a few on hard courts.
• Hot in summer. Dark acrylic soaks up the sun, so the surface can feel well above the air temperature in the afternoon.

Clay courts

Clay courts are loose, crushed material rolled over a firm base. There are two kinds, and they are not the same thing.

Red clay is crushed brick, the surface of the French Open and of most courts in Europe and South America. In the US it is rare. Green clay, often called by the brand name Har-Tru, is crushed basalt, a natural stone. It is the clay you are most likely to find in the US, especially at clubs in the East and the South. It is a little faster and firmer than red clay, but plays far more like it than like a hard court.

What to expect

• Slower, higher bounces. The loose top layer takes speed off the ball and lets topspin kick up. Points last longer, and a big serve is less of a weapon.
• Sliding. You can slide into a shot, which is a skill of its own. It is also why clay is easier on the joints: every stop ends in a short skid rather than a jolt.
• Marks and bad bounces. The ball leaves a mark where it lands, which settles line calls. A patch of loose clay or a raised line tape can also send the occasional ball sideways.
• Upkeep. Clay needs watering, rolling and brushing to stay playable. Many clubs ask players to drag the court with a brush or mat and sweep the lines when they finish. If you see a brush by the fence, that is what it is for.
• Rain. Clay can take a light shower and stays playable through drizzle, but after heavy rain it needs time to drain and often gets closed for the day.

Grass courts

Grass is the original surface, and the fastest. The ball skids and stays low, especially when it is sliced, and the bounce gets less predictable as the lawn wears through a season. Serving and coming to the net pay off more here than anywhere else. Wimbledon is the most famous example.

Real grass courts are rare in the United States. They need a groundskeeper, they cannot be played on when wet, and they wear out quickly. You will find them at a handful of private clubs, mostly in the Northeast. If a listing says grass and it is a public park, treat that with some suspicion until someone confirms it.

Artificial grass and other surfaces

Artificial grass for tennis is a synthetic carpet with sand brushed into it. It plays slower and more evenly than real grass, drains quickly and is gentle on the body. It is common in Britain and parts of Europe and Asia and much less so in the US. Some indoor clubs also use carpet or rubberised surfaces that play fast and low.

Choosing the right court

• Learning or coming back from a break? Start where it is easy to get a court, which in most of the US means a public hard court. The bounce is predictable, and you can turn up without booking.
• Sore knees or a long session ahead? Clay is worth the drive. The give underfoot and the sliding take a lot of the strain out of a long match.
• Practising for a tournament? Play on the surface it is held on. Timing built on a slow court does not carry over to a fast one, and the reverse is just as true.
• Playing in the heat? Clay stays cooler than dark acrylic and is a better choice at midday. See our guide to playing in summer heat.

Shoes for each surface

Tennis shoes are built for side-to-side movement, which running shoes are not, and the sole matters too. Hard-court shoes have a tough rubber sole with a mix of patterns that grips and lasts. Clay-court shoes have a full herringbone (zigzag) pattern that grips the loose surface and does not pack up with clay. Many clubs with clay require shoes that will not mark or tear up the court. All-court shoes are a reasonable compromise if you play on both. Our guide to what to bring to the court covers the rest of the bag.

Finding a court by surface

Court listings on Where.Tennis show the surface wherever we know it, and players who have been there can add it from the court’s menu. Browse by state in the court directory, or open the map to see every court within driving distance of you and whoever you are playing with.
