Seeding a tennis draw by hand is slow and easy to get wrong. Place two strong players together in round one and the whole event feels unfair, so a correct seed list matters for every entrant.
This free tennis tournament seeding calculator works fully in your browser. Nothing you type leaves your device, you need no account, and you can use it as often as you like during the whole season.
Enter one player per line with ranking points. The tool sorts the players, picks the draw size, and places each seed where it belongs in the bracket, without any hand drawing.
The draw size is the next power of two above your player count: 4, 8, 16, or 32. If the draw is bigger than the field, the top seeds receive byes straight into the next round.
To use it, type your data in the box, press the calculate button, and read the result at once. If you change any number, press the button again to see the new result right away, with no waiting and no reload.
Seed 1 goes to the top of the draw and seed 2 to the bottom, so they can only meet in the final. Seeds 3 and 4 sit in opposite halves, and the rest spread out the same way through the draw.
Worked example: with eight players, seed 1 meets seed 8, seed 4 meets seed 5, seed 3 meets seed 6, and seed 2 meets seed 7 in round one. No early clash between favourites spoils the event.
If two players hold equal points, the tool orders them by name so the result stays stable from run to run. Your tournament can still swap equal seeds by hand before the draw is published.
Keep a short written record of every result you enter. Write the date and the score next to the names. That record settles most disputes in a minute, because memory alone is a poor referee when a place is at stake.
Common question: is the result official? No. This tool applies the standard rules described on this page, but your league or tournament director always has the final word when a rule is unclear or two teams finish exactly level.
Common question: can I use it on a phone? Yes. The page works on phones, tablets, and computers, so you can update a table at the rink, on the sideline, in the hall, or at home after the last match.
A steady habit beats a perfect spreadsheet. Update the numbers after each game or round, share the link with captains and coaches, and let everyone see the same table instead of five different versions.
Bookmark this page for the whole season. Recheck it after every round, and come back whenever a new tournament starts. Small, regular updates keep the standings fair for every team in the competition.
Sharing the table is half the job. Send the link to every captain after each round, and post the same link in the team chat, so nobody works from an old screenshot. When everyone sees the same numbers, arguments fade and the focus returns to the games.
When a result is disputed, check the written record first, then the official scoresheet, and only then ask the league director. Most disputes come from a mistyped score, not a broken rule, and a quick check fixes them without a meeting.
A season table and a one-day tournament table need the same care, but a tournament moves faster. Update after every round at the event, because teams that wait until the end often find an error too late to fix fairly.
Free browser tools suit volunteer leagues because there is nothing to install and nothing to pay for. A captain with a phone can run the whole table, which matters when the league budget is zero and the time is short.
