For nearly two decades, Wimbledon stood apart from the rest of tennis in one specific way. It did not seed its men’s draw by world ranking alone. The All England Club applied a bespoke formula that rewarded grass-court results, reshuffling the order of the top 32 to reflect form on the surface. That system is gone.
Since 2021, the men’s seeds at Wimbledon have followed the ATP rankings exactly, the same method used at the Australian Open, Roland Garros and the US Open. This is the history of the formula, how it worked, why it existed and why the All England Club decided it had outlived its purpose.
How the grass-court seeding formula worked
From 2002 to 2019, Wimbledon seeded the men’s singles draw using a calculation built on top of the standard ATP ranking. The formula took a player’s ATP ranking points and added two grass-specific bonuses: 100 percent of the ranking points the player had earned on grass over the previous 12 months, plus 75 percent of the points from the player’s single best grass-court tournament in the 12 months before that.
The combined total set the seeding order. A player’s world ranking still formed the foundation, but recent grass-court performance could lift him several places, or, for a player with a thin grass record, leave him seeded below his ranking. Only the 32 players already in line for an ATP seed were reordered. The formula did not add or remove anyone from the seeded group.
Why Wimbledon used a surface-specific system
Grass once played very differently from hard and clay courts. It was faster, lower and more rewarding of serve-and-volley tennis than baseline play. A player who dominated on clay could arrive at Wimbledon with a high ranking and little prospect of translating it to the lawns, while a grass specialist ranked lower might pose a far greater threat over two weeks.
The seeding adjustment was designed to account for that gap. By weighting grass results, Wimbledon aimed to produce a seeded order that reflected who was genuinely dangerous on the surface rather than who sat highest in a ranking built largely on hard and clay courts.
From committee to formula
Before 2002, the task of adjusting seeds fell to a seeding committee, which had discretion to move proven grass-court players up the order. That subjective system produced disputes, and after friction between the tournament and the players, Wimbledon replaced the committee with the transparent points formula in 2002 as part of an agreement with the ATP. The formula was, in part, an attempt to retain the surface adjustment while removing the appearance of arbitrary human judgment.
The Federer and Nadal example
The formula’s effect was most visible at the top of the draw. In 2019, Roger Federer was ranked third in the world behind Rafael Nadal, but his grass-court record lifted him to the No. 2 seed at Wimbledon, with Nadal seeded third. The reordering placed Federer in the opposite half of the draw to top seed Novak Djokovic, a consequential shift produced entirely by the surface weighting rather than the rankings. Outcomes like that drew criticism from players who felt the work of climbing the rankings across a full season was being discounted.
Why the formula was abolished
The case for a grass-specific system weakened over time. Wimbledon altered the composition of its courts in 2002, and the surface gradually slowed and began to play closer to hard courts. As conditions converged, the sharp distinction between grass specialists and the rest of the field faded, and the transition from clay to grass became routine for the leading players.
In July 2020, with that year’s Championships cancelled, the All England Club announced that the formula would end. From 2021, the men’s singles seeds would be based solely on ATP ranking. The club framed the decision as a recognition that the formula had served its time, citing the strength of modern fields and the changed nature of the courts.
Wimbledon seeding since 2021
Wimbledon seeds the men’s singles draw straight from the ATP rankings at the seeding cut-off date, in line with the other three majors. The practical consequence is that grass-court pedigree no longer protects a top player’s seed. A multiple-time champion whose ranking has slipped will be seeded where the computer places him, with no adjustment for his history on the lawns.
The women’s draw was never governed by the points formula. Wimbledon has long seeded the women’s singles on the WTA rankings, with the Professional Tennis Committee retaining a rarely used right to adjust a seeding within the 32 where it judges a change necessary to produce a balanced draw.
Season Snapshot — June 2026 (volatile data, refresh each cycle)
The men’s singles seeds, set on the ATP rankings at the 22 June 2026 cut-off, show the post-formula system in action:
- No. 1: Jannik Sinner
- No. 2: Alexander Zverev
- No. 7: Novak Djokovic
Djokovic, a seven-time Wimbledon champion, is seeded seventh purely on his ranking, placement the former grass-court formula and its weighting toward Wimbledon results would very likely have raised. Carlos Alcaraz, the world No. 2, withdrew before the seedings with a wrist injury, moving Roland Garros champion Zverev up to the No. 2 seed.
On the women’s side, where the formula never applied, Aryna Sabalenka leads the seeds as world No. 1, ahead of Elena Rybakina and defending champion Iga Swiatek.
Frequently asked questions
Does Wimbledon still use a special seeding formula?
No. The grass-court formula applied to the men’s singles from 2002 to 2019. Since 2021, the men’s seeds follow the ATP rankings, the same as the other three Grand Slams.
What was the Wimbledon grass-court seeding formula?
It added grass-specific bonuses to a player’s ATP ranking points: 100 percent of grass points from the previous 12 months, plus 75 percent of the best grass result in the 12 months before that.
Why did Wimbledon get rid of it?
The courts slowed and began to play more like hard courts, narrowing the gap between grass specialists and the rest of the field. The All England Club ended the formula from 2021.
How is the women’s draw seeded?
On the WTA rankings, with the tournament’s committee holding a rarely used right to adjust a seeding within the 32 to balance the draw. The men’s formula never applied to the women’s event.
