Through 100 metres
To June 21, 2009, the IAAF (and the FSFI before it) have ratified 43 world records in the event.
Records 1922–1976
The "Wind" column in the table below indicates the wind assistance in metres per second. 2.0 m/s is the current maximum allowable, and a negative value indicates that the mark was set against a headwind. the "Auto" column indicates a fully automatic time that was also recorded in the event when hand-timed marks were used for official records, or which was the basis for the official mark, rounded to the 10th or 100th of a second, depending on the rules then in place. A "y" indicates a distance measured in yards and ratified as a world record in this event.

Records from 1975
From 1975, the IAAF accepted separate automatically electronically timed records for events up to 400 metres. Starting January 1, 1977, the IAAF required fully automatic timing to the hundredth of a second for these events.
Wyomia Tyus's 1968 Olympic gold medal performance and Renate Stecher's 1972 Olympic championship win, both in 11.07, were the fastest recorded fully electronic 100-metre races to that time and were ratified as world records. However, Tyus's 11.07 was later adjusted to 11.08.

The triple-jump anemometer, some 10 metres away, read 4.3 m/s, more than double the acceptable limit. Despite the controversy, the record was ratified by the IAAF.
