Multiply the number of balls used per match by the total number of matches in the tournament. The number of matches depends on draw size (128, 64, etc.) and the number of rounds. Additional balls are also lost to the crowd — typically around 10–15 per match at major Grand Slams.
A tennis ball is typically replaced every 7–9 games in professional tournaments. For recreational play, most players replace balls after 1–4 weeks of regular use, depending on court surface and intensity. Hard courts wear balls out faster than clay or grass.
Yes, you can reuse tennis balls for recreational and practice play, even after they've lost some pressure. However, professional tournaments always use new balls at set intervals to ensure consistent bounce and performance standards set by the ITF.
Unopened pressurized tennis ball cans can last up to two years. Once opened, balls typically stay playable for 1–4 weeks depending on use. Storing used balls in a pressurized container can extend their life significantly.
Professional rules typically call for 6 new balls at the start and then replacements every 9 games. For 20 games, you'd likely need around 12–18 balls, depending on the format and how many balls are lost or unusable.
Wimbledon uses approximately 54,000 tennis balls across the entire tournament. Balls are changed every 7 games (and after the first 5 games due to the warm-up period), and additional balls are given to the crowd as souvenirs.
Tennis balls lose pressure and felt quality quickly under professional match conditions, especially on hard and grass courts. Consistent ball performance is critical for fair play and player safety, so tournaments follow strict replacement schedules regulated by the ITF.
Each tennis ball generates roughly 0.26 kg of CO₂ equivalent during its production. A Grand Slam tournament using ~50,000 balls therefore produces around 13,000 kg of CO₂eq. Several organizations and manufacturers are working on recycling programs and pressureless ball options to reduce this footprint.
