Boys 1.6 kg, girls 1 kg, and the plates are different sizes too
NFHS Rule 6-10-4 sets the boys' discus at a 1.6 kg minimum with a 209 to 211 mm diameter, and the girls' at 1.0 kg with a 180 to 182 mm diameter. The girls' plate is genuinely smaller in the hand, not just lighter. Every discus weight in the sport is collected in how much a discus weighs.
