How Many Tennis Balls Are Used In A Match?

Tennis balls are everywhere.

As of 2020, a whopping 325 million are produced every year.

Unfortunately, a lot of used tennis balls end up on landfill sites, but in recent years, there does seem to be a more concerted effort to recycle and find creative ways to reuse them.

The reason for the high turnover of tennis balls is that they don’t last very long.

They lose their bounce fairly quickly as the pressurized air inside the ball gradually leaks out over time.

At the recreational level, you might get a couple of matches out of one set of balls, but at the pro level, they change them a lot more frequently.

In this article, let’s take a look at how many tennis balls are used in a match (at the pro level) as well as some stats on the total number used in each Grand Slam.

How many ball changes are there in a match?

Before looking at the total number of balls used in a typical tennis match, we need to understand the number of ball changes.

At the start of the match 6 balls are used, and then the balls are changed to a new set after the first 7 games. After this the balls are changed every 9 games.

So ball changes occur after the 7th, 16th, 25th, 34th, 43rd, 52nd games etc…

The reason for a quicker change near the beginning of the match is because the players warm up with a set of balls and use the same set for the first 7 games.

There are a couple of exceptions to these rules though:

  • Ball changes never occur at the start of a tiebreak. In this case the ball change rolls over to the first game of the next set. This situation doesn’t happen often, and it would need the first set to finish 7-6 and the score to reach 6-6 in the second set i.e. 25 games would have been played in total.

How many tennis balls are used in match?

As you can see from understanding about ball changes, it’s not easy to calculate the total number of tennis balls.

This is because the longer the match, the more ball changes there are, so the total number will be greater.

At Grand Slam events, more balls will be used in a men’s match (best of 5 sets) compared to a women’s match (best of 3)

We have to work out the average number of games in a match to work out the number of ball changes and therefore the total number of balls.

Firstly, here’s a great table which shows the average number of games in a set from 1997-2007 from a whole range of tournaments. You can see from the data the number lies between 9.5-10 (nearer 9.75), which would seem to indicate that the average score is either 6-3 or 6-4 in a set (closer to 6-4 really)

Therefore on average (assuming 6-4 is slightly more common than 6-3)

  • Win in 2 sets = Average score is 6-4 6-4 = 20 games
  • Win in 3 sets = Average score is 6-3 6-4 6-4 = 29 games
  • Win in 4 sets = Average score is 6-3 4-6 4-6 4-6 = 39 games
  • Win in 5 sets = Average score is 6-3 6-4 3-6 4-6 4-6 = 48 games

Please note, I’m aware these are rough estimates. Often in 5 sets, one player gets a lot more fatigued than the other and may lose the last set 6-1 or 6-2. However, hopefully these numbers aren’t too far off.

Therefore on average, with some number crunching here and there, here are the number of tennis balls used in an “average” match.

  • 2 set match = 20 games = 3 sets of balls = 18 balls in total
  • 3 set match = 29 games = 4 sets of balls = 24 balls in total
  • 4 set match = 39 games = 5 sets of balls = 30 balls in total
  • 5 set match = 48 games = 6 sets of balls = 36 balls in total

So anywhere from 18-36 balls can be used in a tennis match at a Grand Slam.

Not that accurate I know.

However, if you think that in a women’s match the game lasts 2 or 3 sets, and in a men’s game, it’s 3 or 4 (5 sets is less common) then the average number of sets played in a match (including men’s and women’s) is around 3 or 4 (nearer 3)

Therefore the average number of tennis balls used in a match is likely to be around 25.

Before this, the main tennis ball used at the Australian Open was made by Wilson.
