I'm just wondering how much I should weigh for my height and age it would help if someone could tell me thanks so much! :)

Don't want to give you one chart, better to look through:

Everones different, I wouldn't try to achieve a certain height, can't do it, can't do much about age either.
Just try to be "In Proportion".
Try to eat well and Exercise.
