What is the standard net height for the following

Question

elementary High School College Professional

Boys

Girls

Answer 1

2.24meters women

2.43meters men

Answer 2

Junior high school, high school, college, and professional all use the same heights.  I know for the younger ages, USAV lowers the net.  I am not sure that the NFSHSA has an official lower net height.

As mentioned above the men use 7'11 5/8" or 2.43m and the women use  7'4 /18" or 2.24m.

For 13 and 14 year old boys, USAV lowers the net to 7'4 1/8" or 2.24m.

For 11 and 12 year old boys and girls, USAV lowers the net to 7'0" or 2.13 m for boys and girls.  

For 10 and under girls, USAV lowers the net to 6'6" or 1.98m

USAV also lowers the net height for the more senior players as well.  At age 45 and over or 55 and over, USAV lowers the net height as well.
