It's true If ur 11-12 the average height for a boy can be like 5'4-5'7 and a girl 5'2-5'7 if ur 13-14 boy:5'5-5'8 Girl:5'3-6'0 There's more but I don't feel like writing
Thats not a bad thing It's just an AVERAGE height Remember u continue to grow until at least 23 I'm a 5'8
Honestly height doesnt matter But I saw thus show and it says Russian girls are at least 5'4 and this Russian woman was 5'1 and she got knee surgery She stayed in the hospital for a YEAR Guess how tall she is now.. 5'2 36,000,000 dollars for the height to go up from a 5'1 to a 5'2
