What makes each of the four Grand Slams different

Name the Slam from the bounce. Then name who it favours.

Key facts

1
The four majors were founded in this order: Wimbledon in 1877, the US championships in 1881, the French in 1891 (open to all nationalities from 1925) and the Australasian in 1905.
2
Pete Sampras won 14 majors, including 7 Wimbledons, and never won Roland Garros.
3
Björn Borg won 6 Roland Garros titles and 5 Wimbledons, and never won the US Open.
4
Steffi Graf won the Golden Slam in 1988, and Serena Williams completed the "Serena Slam" twice, in 2002–03 and 2014–15.
5
Since 2022, all four majors play a 10-point tiebreak at 6–6 in the final set.
6
Before that rule, John Isner and Nicolas Mahut played a final set of 70–68 at Wimbledon in 2010.

Why it works

A surface acts on the ball twice. Friction grips it and takes forward speed. Restitution decides how much vertical energy comes back. Clay's gritty top layer bites, so the ball comes through slower and higher, right into a topspin player's strike zone.

Grass is slick, so the ball skids low and fast, and the serve and first strike decide the point. Hard sits in between, with its pace tuned by the sand in the coating. The two hard-court majors don't play the same as each other either.

The venues add what the surface doesn't. Men play best of five sets and women best of three. Winning all four in one year is the Grand Slam. Winning all four across a career is the career Grand Slam, the test of a complete game.

The line to say on court
“Same ball, four courts, four sports. Read the bounce before the player.”

Calling any major a Grand Slam

Strictly, a Grand Slam is all four majors in one year. The career version is all four ever.

Questions players ask

What surface is each Grand Slam played on?

Roland Garros is clay, Wimbledon is grass, and the Australian Open and US Open are hard courts.

What is the difference between a Grand Slam and a career Grand Slam?

A Grand Slam is winning all four majors in one calendar year. A career Grand Slam is winning each of the four at some point in a career.

Why do some great players never win certain Slams?

Each surface rewards a different game. Sampras won 7 Wimbledons and never won on the clay of Roland Garros, and Borg won 11 titles in Paris and London but never the US Open.

Is Wimbledon grass as fast as it used to be?

No. Today's grass plays slower and bounces higher than it did in the 1990s. Surface speed drifts with court preparation and ball choice.

What this doesn't cover

Surface speed changes with court preparation and ball choice, so fastest and slowest are historical tendencies, not constants. Per-Slam statistics like ace rate or rally length depend on results data and aren't quoted here.

Play the pointHow clay, grass and hard courts change your gameClay, grass and hard courts play differently because of two things at the bounce: friction, which takes forward speed, and restitution, which sets bounce height. Clay grips the ball and kicks it up, so points run longer. Grass is slick, so the ball skids low and rewards the serve and first strike. Hard courts sit between, tuned by the sand in the coating.StrikeWhy topspin kicks up and slice stays low after the bounceTopspin kicks up and forward after the bounce because the court's friction grabs the bottom of the ball and throws it on, while slice skids through low. At touchdown, friction takes horizontal speed and restitution returns part of the vertical speed. So read the spin in the air and set your racquet for the height the ball will reach, not the height it arrives at.Know the gameWhat is the Open Era in tennis, and why does 1968 matter?The Open Era is tennis since 1968, when the majors first let professionals and amateurs play in the same draws. Before it, the best players were barred from the majors for taking money. That's why records carry a start date: Margaret Court has 24 majors across both eras, and Serena Williams holds the Open Era women's record with 23.Know the gameHow a tennis tiebreak works, and who serves whenA tennis tiebreak is played at 6–6 and won by the first player to 7 points with a two-point lead. One player serves the first point, then serve alternates every two points, 1-2-2-2, and players change ends every six points. A match tiebreak works the same way but goes to 10. Since 2022, all four Slams use it at 6–6 in the final set.
