Both the men's and ladies' singles consist of 128 players. Players and doubles pairs are admitted to the main events on the basis of their international rankings, with 104 direct entries into the men's and 108 into the ladies' competitions. Both tournaments have 8 wild card entrants, with the remainder in each made up of qualifiers. Since the 2001 tournament, 32 players have been given seedings in the Gentlemen's and Ladies' singles, 16 teams in the doubles events. The system of seeding was introduced during the 1924 Wimbledon Championships. This was a simplified version allowing countries to nominate four players who were placed in different quarters of the draw. This system was replaced for the 1927 Wimbledon Championships and from then on players were seeded on merit. The first players to be seeded as no. 1 were René Lacoste and Helen Wills.
