How to run a round-robin tournament with 4, 6, or 8 teams

Round-robin is the format where every team plays every other team once. It's the right choice when you want everyone to play similar amounts of football, the score difference matters less than the playing experience, and you have time for more matches than a knockout would need.

The maths is simple but the practical timing isn't always obvious. Here's what you actually need to know for the three most common team counts.

4 teams: 6 matches, ~45 minutes

Four teams play 6 matches total in a single round-robin. Every team plays 3 matches each. The matches break naturally into 3 rounds of 2 simultaneous matches:

• Round 1: A vs B, C vs D
• Round 2: A vs C, B vs D
• Round 3: A vs D, B vs C

If you have two pitches, you can play both matches in each round simultaneously. With 6-minute matches and 90-second changeovers, the whole tournament finishes in about 30 minutes. With 8-minute matches and 2-minute changeovers, around 45 minutes. Add 5 minutes for an awards ceremony at the end.

One pitch only? Double the time — about 60-90 minutes total.

6 teams: 15 matches, ~75 minutes

Six teams need 15 matches in a round-robin (every team plays 5 matches). The schedule splits into 5 rounds of 3 matches each — but you need three pitches to run them simultaneously, which most grassroots venues don't have.

The realistic options:

• Two pitches: Some matches play simultaneously, some don't. Plan for ~75 minutes of total play time at 5-minute matches.
• One pitch: Sequential play. ~120 minutes total at 5-minute matches. Probably too long for kids; consider 4-minute matches to fit in 90 minutes.

At 6 teams, the round-robin starts becoming a meaningful time commitment. Consider whether you really need everyone playing everyone, or whether two groups of 3 with a final between group winners (a 'mini-cup' format) would work better.

8 teams: 28 matches, way too long for one session

8 teams in a single round-robin is 28 matches. Each team plays 7 matches. Even with three pitches and short matches, this is a 2-3 hour commitment. Don't try to run a single round-robin with 8 teams in one grassroots session.

What works at 8 teams:

• Two groups of 4 + final: Each group runs a 4-team round-robin (6 matches each, 12 matches total), then top two from each group play semi-finals and a final. Total: ~16 matches. Manageable in 90 minutes.
• Group stages over two sessions: Run the round-robins on Saturday, finals on Sunday or the following Saturday. Real tournaments do this; nothing wrong with grassroots copying it.

How to choose the right format

Round-robin works best when you want:

• Everyone playing roughly the same amount
• The 'who's actually best over the course of a tournament' answer (rather than who got lucky in one match)
• Late matches that still matter (no team is eliminated early)

Knockout works better when you want:

• Quick determination of a winner
• Drama (every match is do-or-die)
• Less total match time

Both formats are supported in the tournament builder, including double round-robin (home and away) and knockout brackets up to 16 teams.

Equipment minimum

For a 4-team round-robin you need: a way to mark the pitch (cones work), 2 small goals (or 4 cones for cone goals), 1 ball per match, bibs in the team colours, a stopwatch or phone timer, and a way to record scores. The tournament equipment guide covers the rest.

The actual tool

Punching all this into a calculator manually is tedious. The Build A Tournament tool generates the full fixture list, schedules byes correctly for odd team counts, and updates the league table live as you punch in scores. Free, no signup, works on your phone at the side of the pitch.
