When you are playing in your own backyard, you can make up your own rules and keep score any way you like. But when you play in a competition that follows the ITTF rules and regulations, it's important to know how to keep score correctly, in case you are asked to umpire, or just to make sure that your umpire is keeping the correct score. In fact, it is not uncommon for matches in local competitions to have no umpires, and the players must umpire and keep the score themselves.
So just in case you are asked to umpire, or have to umpire your own match, here is a checklist of how to keep score in table tennis.
Before the Match Starts
Make sure that you get the match scoresheet and a pen or pencil, so that you have something to write the scores on as each game finishes. Don't wait until the end of the match to write down the scores, or you may not be able to remember them all! It also helps to check the scoresheet to make sure that you have the correct opponent and are playing on the correct table.
- Check whether the match is a best of 5 or 7 games (these are the most commonly used by far, although any odd number of games can be used).
- Do the toss to decide who will be serving, and which player will start at which end. Most official umpires use a colored disc to do the toss, but a coin will work just as well. Another alternative which is commonly used is to roll the ball along the middle of the table towards you and let it fall off the endline, catch the ball with both hands, then spread your arms out with both hands below the table, one hand holding the ball. Your opponent then tries to guess which of your hands has the ball. If he guesses correctly, he has the first choice of serve or ends. If he guesses incorrectly, the first choice is yours.
- Make a note on the scoresheet about which player is going to serve first in the first game. This will come in handy in later games to know whose turn it is to serve first, or if you or your opponent forget whose turn it is to serve during a game!
The score begins at 0-0, and the server will serve first. Each player gets to serve for two points in a row, and then the other player has to serve. You are not allowed to give the serve away and choose to receive all the time, even if both players agree.
- When serving, you must follow the rules for a legal serve, and hit the ball so that it touches your side of the table once, then bounces over or around the net, and then touches your opponent's side of the table. A serve that touches the net assembly (the net, net posts, and net clamps) on the way, but still touches your side first and then your opponent's side on the second bounce, is called a let serve (or just let) and must be replayed, with no change to the score. There is no limit on how many lets you can serve in a row.
- If you are playing doubles, you must serve the ball diagonally so that it bounces first in the right hand half of your side of the table, goes over or around the net, and then bounces in the right hand half of your opponents' side of the table (their right hand side, not yours!).
- Your opponent will then attempt to return the ball over or around the net so that it bounces first on your side of the table. If he cannot, you win the point. If he does, you must hit the ball over or around the net so that it bounces first on his side of the table. If you cannot, he wins the point. Play continues in this manner until either you or your opponent cannot return the ball legally, in which case the other player wins the point.
- In doubles, each of the players take turns to hit the ball. The server hits the ball first, then the receiver, then the server's partner, then the receiver's partner, and then the server again. If a player hits the ball when it is not his turn, his team loses the point.
- When a point is won, that player or team adds one to their score. A game is won by being the first player or team to reach 11 points, with a lead of at least 2 points. If both players or teams reach 10, then the game is won by the first player or team to get two points ahead. Also, if a score of 10-all is reached, both players or teams will only serve 1 serve each until the game is won. The score is called out with the server's score first.
- In the final possible game of a match, when the first player or team reaches 5, the players must change ends. If it is a doubles match, the players also change the order of receivers.
