These are starting estimates—not prescriptions. Wingspan is usually more useful than height, and actual counts change with speed, fatigue, breathing, technique and underwater distance.

How to use these estimates
The chart is for freestyle and uses swimming distance (pool length minus push-off) divided by estimated distance per stroke. Test the range in the pool and record the athlete’s demonstrated working counts.
