Javelin weight depends on age and gender. HS boys throw an 800g javelin; HS girls throw 600g. College men use 800g; college women use 600g. Below: the full chart, plus what changes when the implement changes. The length windows and the balance point that actually govern how a javelin flies are set out in how much a javelin weighs.
Standard 800g javelin across NFHS and NCAA men's competition. World Athletics uses the same weight for elite competition. Which states actually contest the event is the harder question, and it is answered on the high school javelin weight page.
Standard 600g javelin from HS through NCAA and World Athletics. The implement length stays constant across levels.
USATF runs its 13-14 division on a 600 g javelin for boys and girls alike, then splits at 15-16 with boys moving to 850 g. Below that, 11-12 throws a 450 g aero javelin. The lighter implement lets younger athletes develop release mechanics without overloading the shoulder.
Release angle, velocity, and crossover step pattern vary by implement. AI knows the javelin and grades against the right standards. Film your throw, get the right analysis.
