A set in tennis is usually played for six games. However, if the score reaches six games in total, the set is played to eight games. If the score then reaches eight games, the set is played to 10 games. However, if the player who is ahead in the score wins the next game, they win the set. A player must win by two clear games to win a set.

The standard length of a single set in professional tennis is six games. The first player to win six games by a margin of two or more games wins the set. If the score is tied at 6-6, a tiebreaker is played. In a tiebreaker, the first player to reach seven points by a margin of two points wins the set.
