Tennis tournament

Tournaments are often organized by gender and number of players. Common tournament configurations include men's singles, women's singles, doubles (where two players of the same gender play on each side), and mixed doubles (with a member of each gender per side). Tournaments may be arranged for specific age groups, with upper age limits for youth and lower age limits for senior players. There are also tournaments for players with disabilities. In the four Grand Slam tournaments, the singles draws are limited to 128 people for each gender.

A singles player or doubles team that wins all four Grand Slam titles in the same year is said to have achieved the Grand Slam or a Calendar Year Grand Slam. If the player or team wins all four consecutively, but not in the same calendar year, it is called a Non-Calendar Year Grand Slam. If a player wins all four at some point in his or her career, even if not consecutively, it is called a Career Grand Slam.

The four Grand Slam tournaments are the most important tennis events of the year in terms of world ranking points, tradition, prize-money awarded, and public attention. They are:

1. Australian Open
2. French Open
3. Wimbledon
4. U.S. Open
