Pit depth by rule body
NFHS and World Athletics both set minimum depth standards, and most current competition pits run 24-26 inches deep to handle 5-6+ meter landings safely. Training and youth-level pits sometimes run shallower, 16-20 inches, which is adequate only for lower bar heights, and programs upgrading to a full-depth pit usually do so as bar heights in their program start climbing past 12-13 feet. Neither rule book publishes one exact universal number, they specify performance-based safety requirements that manufacturers then engineer to.
