What is the ideal weight for someone age 22 and 5 foot 4 inches tall?

I can't tell you the exact ideal weight, but I can give you a link to a site where you can calculate your BMI (body mass index)). On the page I'm giving you at the left hand side, it tells you BMI categories (from underweight to obese). You can use the BMI calculator to figure out your BMI from your height and weight, and then see whether your weight is ideal. Hope this helps:
