NCAA pool: 25 yards (short-course yards, SCY) or 25 meters (short-course meters, SCM) — NCAA championships are contested in SCY; Some training facilities + select championships use 50-meter long-course (LCM); Lane width: 7 ft minimum (NCAA championship requires 9 ft)
Why people argue about this
People often assume that the 25-yard minimum refers to the length of the pool from one end to the other, but actually it's about the width of the lanes when multiple swimmers are racing in them. They overlook the fact that this rule ensures each swimmer has enough space to maneuver without hitting another lane, which is crucial for fair competition and safety.
