How many points will it take to decide a winner in tennis?

Answer 1

This depends on a lot of things. One set requires a minimum of 24 points to be won by one player.

Some mathes are one set, some are best of 3 sets, some are best of 5 sets, some are best of 3 sets with the 3rd set being a match tie-break (first to 10 points but must win by 2 points. Eg. 10-8 or 13-11 or 24-22 etc.).

Most tennis matches are best of 3 sets. This means that the first player to get 2 sets wins the match. The player will need a minimum of 48 points.

I hope this answered your question. But there are too many things to depend on to win a match. One match can take over 1,000 points (even though it is very, very, very unlikely).
