How Many Tennis Tournaments Are There Around the World?
Ask a simple tennis question and, very often, the sport hands you a draw sheet the size of a tablecloth.
So, how many tennis tournaments are there around the world? The honest answer is: it depends what you mean by “tennis tournament”.
If you mean the events most fans see on television, the number is roughly in the low hundreds each season across the ATP Tour, WTA Tour and the four Grand Slams. If you include Challenger events, ITF tournaments, juniors, wheelchair tennis, seniors, national championships, college tennis and local club events, the answer quickly becomes many thousands worldwide every year.
That is not a dodge. It is the way tennis is built.
The short answer is that there are more than most fans realise
For most of us, the tennis year feels like it revolves around the familiar landmarks: the Australian Open, Roland-Garros, Wimbledon and the US Open. Add Indian Wells, Rome, Madrid, Miami, Queen’s, Cincinnati, the Finals, a few clay-court weeks in Europe, and suddenly the calendar already looks full enough to require its own physio.
But those are just the top shelf. If you fancy diving deeper into it TENN360 break down each tournament as it comes, just check our 'Tour' page.
But, professional tennis has several layers:
Level | What it includes | Rough scale |
Grand Slams | The four biggest tournaments in tennis | 4 events per year |
Main ATP and WTA Tours | Regular top-level men’s and women’s tournaments | Dozens each per season |
ATP Challenger Tour | Men’s events below the ATP Tour | Many events across the year |
ITF World Tennis Tour | Entry-level professional events for men and women | Hundreds of events worldwide |
Juniors, wheelchair, seniors and national events | Official and semi-official competitive tennis | Hundreds more |
Local and club tournaments | County, regional, league and club events | Thousands globally |
So if someone asks for one clean number, the fairest fan-to-fan answer is this:
There are roughly a hundred major professional tennis tournaments in a season, but many hundreds of sanctioned pro events, and thousands of tournaments worldwide once every level of the sport is counted.
That is why tennis can feel both intensely global and oddly local. One week, the sport is on Centre Court. The next, someone is playing a hard-fought final beside a leisure centre car park with three spectators and a dog who has no concept of let cords.
What counts as a tennis tournament?
This is where the number changes.
A tournament is simply an organised competition where players enter, matches are played, and winners progress through a draw or group format. But tennis uses the word for very different things.
A Grand Slam is a tournament.
A WTA 250 or ATP 500 event is a tournament.
An ITF W15 event, where a young professional might be chasing ranking points and prize money, is also a tournament.
So is a junior national championship. So is a wheelchair tennis event. So is your local club championship, provided someone has made a draw, booked courts and started arguing about whether matches should be best of three sets or a match tie-break.
The confusion comes because fans often use “tournament” to mean “big televised event”. The sport itself uses it far more broadly.
The professional calendar has several different ladders
Tennis is not one tour. It is a set of connected ladders.
At the top sit the Grand Slams, which are run separately from the ATP and WTA tours. Beneath and around them are the ATP Tour and WTA Tour, where established professionals compete week after week.
Below that, the ATP Challenger Tour gives men a route from the lower ranks towards the main tour. The ITF World Tennis Tour does similar work at the entry level for both men and women. Players often spend years moving between these layers, trying to gather ranking points, confidence and enough prize money to keep travelling.
That last bit matters. These are not just abstract calendar entries. They are workplaces. A player ranked outside the spotlight might play in Europe one week, North Africa the next, then Asia or South America soon after. Tennis may look glamorous on television, but at the lower levels it can involve budget flights, laundry puzzles and a very personal relationship with airport sandwiches.
The number of tournaments changes each year because calendars change. Events move, pause, merge, upgrade, downgrade or disappear. New ones appear too like ATP Lyon this year. That is why any exact global total goes out of date quickly.
The biggest events are only a small part of the world game
The tournaments most fans recognise are the ones with the best players, bigger crowds and ranking weight.
They include:
The four Grand Slams
ATP Masters 1000 events
WTA 1000 events
ATP 500 and WTA 500 events
ATP 250 and WTA 250 events
Year-end finals
Team events and national competitions
These make up the visible tennis season. They shape the headlines, the rankings and the arguments in group chats. Was that a good draw? Should they have played doubles? Why is the camera angle so low? All the essentials.
But the sport does not begin there.
For every player walking onto a show court, there are others trying to qualify at smaller events, juniors testing themselves internationally, wheelchair players travelling the circuit, and club players entering county tournaments because someone convinced them it would be “fun”.
Why the exact number is so hard to pin down
There are three main reasons.
The calendar is always moving. Tennis is played almost all year, across continents, surfaces and competition levels. A tournament count in January may not match the final count by December.
Different bodies run different events. The Grand Slams, ATP, WTA, ITF, national associations and local organisers all operate their own competitions. There is no single everyday list that captures everything from Wimbledon to a village mixed doubles event.
The definition changes the answer. Count only top-level professional events and the number is manageable. Count every recognised tournament and it balloons. Count informal local events too, and you are into a number nobody can sensibly track in real time.
This is why tennis sometimes feels bigger than its headlines. The professional game we watch is the bright tip of a very large iceberg, although admittedly an iceberg with clay stains and a slightly chaotic order of play.
So what is the best number to remember?
If you want a useful answer rather than a fake exact one, think of it in three bands.
Major professional tournaments
Roughly a hundred or so events each season, once you include the Grand Slams and main ATP and WTA Tour events.
All professional tournaments
Many hundreds each year, once you add Challenger and ITF events around the world.
All organised tennis tournaments
Thousands worldwide every year, once junior, wheelchair, senior, national, regional, university, school and club competitions enter the picture.
That is the answer I would keep in your back pocket. Tennis is not just a tour, or even two tours. It is a pyramid, with the Grand Slams at the glittery top and countless smaller events holding the whole thing up.
The next time someone says there is “no tennis on this week”, they probably mean there is no marquee event on their TV package. Somewhere, almost certainly, a match is at 4-4 in the third, someone is questioning a line call with great emotion, and another tiny part of the global tennis calendar is doing its job.
