[2] The Badminton World Federation (BWF) rankings are used to determine the qualification of the players for the tournament.
Similar regulations also apply to the players competing in the doubles, as the NOCs (National Olympic Committees) can enter a maximum of two pairs if both are ranked in the top eight, while the remaining NOCs are entitled to one until the quota of 16 highest-ranked pairs is filled.
The host nation, if it has not already qualified two competitors, receives at least either two singles players or one pair.

In the 2012 Summer Olympics, China became the first country to win all five disciplines' gold medal in history, and as of 2024 the only clean sweep in the same Games.
