How to run a tennis box league: rules and scoring

A box league is the easiest competition a club can run that gets people playing every week. It suits the members who would never enter the club championships, and it fills the courts on the evenings that are usually quiet.

At its best, a box league is about community and friendly competition. Players get a regular match against people of their own standard, and a reason to talk to members they would never otherwise have met. The rules below matter, but they are there to keep it friendly.

What is a box league?#

A box league is a club competition in which players are split into small groups, called boxes, of a similar standard. Everyone in a box plays everyone else once before a closing date. Then the top of each box moves up a box, the bottom moves down, and the next round starts.

How does a box league work?#

1. Rank your players and split them into boxes of five to eight.
2. Set a closing date for the round.
3. Players arrange their own matches and play everyone in their box.
4. Results go on the table as they are played.
5. At the closing date, the top of each box goes up and the bottom goes down.
6. The next round starts straight away.

A box league runs all year like this, round after round, and a new member can join at the start of any round.

How many players to put in each box#

Five to eight. Every player in a box plays every other, so the size decides how many matches each player owes and how long the round needs.

Players in a box	Matches each	Matches in the box	A round of about
5	4	10	four weeks
6	5	15	five weeks
7	6	21	six weeks
8	7	28	seven weeks

You will often read that boxes of four to six are best. Five to eight works better for most clubs. A box of four gives each player only three matches, and if one player drops out the box barely runs. The LTA’s own guide to running internal club competitions suggests six to eight.

Group players by standard. For the first round, use whatever you already know: last year’s championship results, the club’s own grading, or your best guess. It does not need to be right. Promotion and relegation will sort the order out within two or three rounds.

How long each round should run#

A week per match is a fair rule, and the LTA guide suggests the same: one match a week, or one every other week. Members with families or shift work can fit one match a week. Two a week is where matches start going unplayed.

Give every round a fixed closing date and say it when the round opens. Shorter than the table above, and the busy players cannot fit their matches in. Longer, and people forget there is a match to arrange until the last week, when every court is taken.

Start the next round as soon as the last one closes. A gap of a fortnight between rounds is where box leagues lose their players.

Match formats for a box league#

Pick a format that fits the court booking. A match that runs past the hour is a match somebody cannot book.

Format	How long it takes
Two FAST4 sets and a match tiebreak	about an hour
Two tiebreak sets and a match tiebreak	about an hour and a quarter
Best of three tiebreak sets	an hour and a quarter to an hour and a half
One full set	half an hour to forty minutes

Timings from the LTA’s guide. Two sets with a ten-point match tiebreak in place of the third is the most common format in club box leagues. FAST4 sets are first to four games, with a tiebreak at three all and no advantage at deuce; the LTA publishes the full FAST4 rules.

Box league rules to agree before the first round#

Most arguments in a box league are about the same five things, and every one of them is easier to settle before it happens:

1. The match format. One from the table above, the same for every box.
2. Who arranges the match. Either player may, and the one who is asked offers at least three dates, a few days apart.
3. What a no-show costs. A player who turns down three dates and offers none of their own loses the match on a walkover. So does a player more than thirty minutes late.
4. Who books the court and brings the balls. Usually the player who arranged the match books, and the other brings balls.
5. How the box is ranked. Points first, then the result between the two players, then sets, then games.

Put the rules where every player can read them, and point to them when somebody asks. You stop being the referee when the answer is written down. For a full set of rules to copy and change, use the box league rules template.

Box league scoring#

Keep it simple enough that players can work out the table themselves. This scheme rewards turning up and a close loss as well as a win:

Result	Points
A win	3
A loss, having won a set	1
A loss in straight sets	0
A match not played by the closing date	0 for both

Clubs use several other schemes. Each one rewards something slightly different:

Scheme	How it scores	Suits
Win, and a set point	3 for a win, 1 for a loss with a set	Most clubs: simple, and a close loss counts
Sets won	1 point for every set won	Boxes where most matches go to a tiebreak
By the score	4 for 2-0, 3 for 2-1, 1 for 1-2, 0 for 0-2	Keen boxes that want every set to matter
Points for playing	2 for a win, plus 1 for playing at all	Clubs whose problem is unplayed matches
Games won	Every game won counts	Short formats, such as one set or FAST4

Whatever you choose, use the same scheme in every box and every round.

When players finish level on points, the result of the match between them decides. If three are level, the matches between those three decide. If that still does not, sets won minus sets lost does, then games won minus games lost.

A worked example: one box of five#

Priya, Sam, Jo, Alex and Tom play a round under the scheme above. Ten matches, four each. This is the final table:

Player	Played	Won	Sets	Points
Priya	4	3	7-3	10
Sam	4	2	5-5	7
Jo	4	2	5-6	7
Alex	4	2	5-5	7
Tom	4	1	3-6	4

Sam, Jo and Alex finish level on seven, so the matches between those three decide. Sam beat both, Jo beat Alex, and that is the order. Priya goes up a box, Tom goes down, and the other three stay.

Promotion and relegation between boxes#

At the end of each round the winner of each box goes up one box and the last player goes down one. With seven or eight in a box, many clubs move two each way. Everyone else stays where they are.

Many clubs add one condition: a player must play at least two or three matches to go up. It stops somebody winning a box by playing once.

When things go wrong#

A player drops out part way through a round. Either keep the matches they played and count the rest as not played, or remove all their results so nobody in the box is helped or harmed. Removing them is fairer. Pick one, and write it down.

A player plays nothing. They go down a box at the end of the round. After two rounds with no matches, take them out of the league until they ask to come back.

A match is stopped by rain or bad light. Finish it from the same score another day, before the closing date.

A player retires injured. The match goes to their opponent, and the score at the time counts for sets and games.

The numbers do not divide. Twenty-three players do not make even boxes. Run some boxes of six and some of five, and keep the smaller ones at the bottom.

Doubles box leagues#

Two ways work. With fixed pairs, each pair is one entry in the box and plays every other pair, exactly like singles. With rotating partners, everyone in the box partners everyone else once, and each player scores their own points. Fixed pairs suit established partnerships. Rotating partners suit a club night crowd, and need a box size the rotation divides into, such as four or eight.

Juniors#

Match the format to the ball. Younger players on red and orange balls play short formats, such as best of three tiebreaks. Green and yellow ball players can play the same format as the adults. Parents usually arrange the matches, so ask them for consent to share a contact number when their child enters.

Placing new players#

A new player joins the bottom box, or the box that matches their standard if you know it. Never place a newcomer above an existing player at that player’s expense: put them in the box, and let the results decide. A player’s World Tennis Number is a fair guide to which box to start them in.

How to keep a box league going past the second round#

The first round always goes well. The second round is where box leagues drift, usually because one or two matches in each box are never played and the players in them lose interest.

The best box leagues are well organised, and they celebrate the wins, the upsets and the newcomers.

Four things keep a league busy and friendly:

• A group chat for the league. A WhatsApp group where players arrange matches, post their scores and congratulate each other does more than any rule. It shares phone numbers, so ask everyone before you add them.
• The tables, posted often. Post every box’s table every week or two, not just at the end. Name the players who have not played yet, kindly, and they will get matches booked.
• Something to celebrate. Make a fuss of the box winners, the upset when somebody beats a player a box above, and a newcomer’s first win. People come back to a league that notices them.
• The closing date, kept. Close the round on the day you said. Extending it once teaches everyone the deadline is not real.

Start every round with one clear message. Change the words in brackets and send it to each box:

Then, halfway through, name the matches still to play:

Some members will never send a match request, however clear the reminder. Others would rather choose their own opponents. If that sounds like part of your club, read ladder or box league: which suits your club, and the ladder rules for a tennis club.

Running a league with many boxes#

Once a league has more than four or five boxes, one organiser cannot chase every match. Give each box a box manager. That is a player in the box who keeps an eye on its matches, nudges the slow ones and reports the results to the organiser.

The organiser then deals with a handful of box managers instead of forty players. It also spreads the friendly part of the job: every box has somebody who knows everyone in it.

Once the league is running, how to level up your tennis box league covers what to add next. That means live tables, easier arranging, results worth celebrating and a level for every player.

Running it without the spreadsheet#

Most box leagues start on a spreadsheet and a group chat, and that works for a while. It stops working when the organiser goes on holiday. It also stops when the league grows past forty players and the Sunday evening spent updating the table becomes the job. Starting on a spreadsheet? The free box league spreadsheet works its own table out. A box league spreadsheet template for your club covers the mistakes that break one.

A system like Clayside makes the tables, the arranging and the key results visible to everyone. Players arrange their matches and put in their own scores, every box’s table updates as they do, and the wins and upsets show for the whole club. Each box manager looks after their own box, and the organiser sees all of them.
