How to Create a Tennis Tournament Bracket (Draw) – Step by Step
What a tournament bracket is, how seeding and byes work, and how to create a fair tennis draw for your club tournament.
What is a tournament bracket?
A tournament bracket (or draw) is the structure of a knockout tournament. It shows who plays whom and how winners advance round by round until the final. A good bracket is fair, balanced and keeps the strongest players apart until late in the tournament.
Brackets are built in powers of two: 8, 16, 32, 64 or 128 slots. If you have fewer players than slots, the gaps are filled with byes.
Step 1: Choose the draw size
Pick the smallest power of two that fits your field. 12 players? Use a 16-draw with 4 byes. 20 players? Use a 32-draw. The fewer byes, the more balanced the tournament.
Step 2: Seed the strongest players
Seeding prevents the best players from meeting in round one. The basic rules:
- The number 1 seed goes to the top of the bracket, the number 2 seed to the bottom
- Seeds 3 and 4 are placed so they could only meet the top seeds in the semifinals
- The remaining players are drawn randomly into the open slots
Seeding can be based on your league ranking, last year's results or the organizer's assessment.
Step 3: Assign byes correctly
Byes (free passes to round two) go to the top seeds first. That rewards the strongest players and keeps the early rounds balanced. Never give a bye randomly to an unseeded player while a seed has to play.
Step 4: Pick the match format
For a one-day tournament, keep matches short so the schedule holds:
- Short sets (sets to 4) for many matches in little time
- Match tiebreak instead of a third set
- Best of 3 for the final rounds if time allows
Step 5: Advance winners and keep the bracket live
After each match the winner moves to the next round. A live bracket that everyone can follow builds excitement and saves you from constant questions about who plays next.
