Free League Schedule Maker

A league schedule maker takes your list of teams and builds the season for you: who plays whom in each round, who is home and who is away, and, if you add them, the date, time and court of every game. This one uses a round robin, so every team plays every other team the same number of times.

To use it, type your team names in step 1, one per line. Pick Single (everyone meets once) or Double (everyone meets twice, once at each home) and your sport, then press Generate schedule. The sport only changes the labels and the default game length, so it works as a basketball, softball, baseball, soccer, volleyball or pickleball league schedule maker. Add dates and courts in step 3 if you want game times; leave it off to get numbered rounds you can play on any night.

The circle method

Round robin generators use a simple trick called the circle method. Put one team in the middle and the others around a circle. In each round, the team in the middle plays one team on the circle, and the rest pair up straight across. Then every team on the circle moves one place and you play the next round. After one lap, every pair has met exactly once.

Here is the whole thing for 4 teams. Team 4 stays in the middle and meets Teams 1, 2 and 3 in turn:

1. Round 1: Team 1 vs Team 4, Team 2 vs Team 3
2. Round 2: Team 3 vs Team 1, Team 4 vs Team 2
3. Round 3: Team 3 vs Team 4, Team 1 vs Team 2

That’s 3 rounds and 6 games, and each team plays 3 games. The team listed first is at home. The home side alternates, so no team has more than 2 home games or 2 away games in a row, and each team’s home and away games differ by at most one.

The numbers grow quickly. With n teams a single round robin has n × (n − 1) ÷ 2 games: 6 teams play 15 games, 8 teams play 28 and 12 teams play 66. An even number of teams needs n − 1 rounds; an odd number needs n rounds, because one team sits out each round.

These tables come from the same engine as the tool above, so they match what you get when you generate a league of that size. Each cell is one game with the home team first. To use one on paper, number your teams (or draw numbers from a hat) and read across each round.

With an odd number of teams, somebody has to sit out every round. That round off is called a bye. The standard fix, and the one this tool uses, is to add a pretend “bye” team to make the count even and run the circle method as usual. Whoever is drawn against the bye has the round off.

That gives a fair result: every team gets exactly one bye in a single round robin (two in a double), and there’s only one bye per round. A 7-team league plays 7 rounds of 3 games, 21 games in all, and each team plays 6 games and sits out once. A 5-team league looks like this:

A double round robin plays the whole cycle twice. The second time through, home and away are swapped, so each pair meets once at each home. For 8 teams that’s 14 rounds and 56 games. Pick Double in step 2 to use it as a double round robin generator. With an even number of teams the second half starts from round 2 instead of round 1, so no team gets 3 home or 3 away games in a row across the halfway point. In every double schedule, a pair’s two games are at least two rounds apart.

Leagues with divisions

Big leagues often split into divisions so the season stays short. A single 12-team round robin needs 11 rounds and 66 games. Two divisions of 6 each need only 5 rounds, with 15 games per division.

To build a league schedule with divisions here, make one schedule per division:

1. Enter the first division’s teams and generate its schedule.
2. Download it (Excel or CSV is easiest to combine), or copy the Share link.
3. Clear the teams, enter the next division and generate again.

If the divisions share a gym or field complex, give each one its own night or its own courts so their game times don’t clash. After division play, many leagues add a few crossover games or a playoff between the division winners, which you can schedule by hand once the standings settle.
