BBC Sport tennis. The rules of scoring. The maximum number of sets in a match is five for men and three for women. Usually the first player to win six games wins a set but if the score becomes five-games-all, one player must be two games ahead to win the set. So a player must win the set 7-5 or 8-6 or 9-7 and so on.
The tennis scoring system is the standard system by which tennis matches and tournaments are generally operated and scored. A tennis tournament is organized into matches between players (for singles tournaments) or teams of two players (for doubles tournaments). The matches of a tournament are grouped into rounds. In round 1, all players (or teams) are paired and play against each other in matches. The losers are said to leave, or be out.
