The record shelf

I expected Wimbledon and the USTA campus in Orlando to be the extremes. Neither is: a public sports ground in Saitama, Japan has more courts than either, and the loneliest court in the data is 2,406 km from the next one. All of it is measured from the same data as the map.

How big is your club?

  5. Tennis city 50+ courts 8 facilities

Also on the site: the four Grand Slam venues, counted — and the rest of the tour.

How we count

Deduplicated. The OpenStreetMap extract emits some courts twice (the pitch and its area); we collapse every pair within ~1 m, leaving 581,934 real courts.

Grouped. Courts within 60 m of each other become one facility. That is wider than the gap between courts in a club and narrower than the gap between neighbouring clubs. Clusters that OpenStreetMap gives the same name and that sit within 400 m are one club with two blocks, so they are joined back together. Unnamed courts are never merged this way — that is what would chain a whole suburb. 292,411 facilities came out of it, 105,902 with more than one court.

Naming. Where OpenStreetMap has no name for a facility, the page says Unnamed complex and gives the nearest town.

Known gaps. OpenStreetMap is incomplete. The USTA National Campus in Orlando advertises more than 100 courts and is mapped at 78, so it does not rank first here. If a club is wrong, editing OpenStreetMap is the fix: the map and this page rebuild from it.
