I am 5"4" and 9st 7lbs what is my ideal weight?

There is no "average" height for someone of any age to be as we're all different and unique. Let me explain why, in short if we where to take the average height of a MALE, ( you forgot to include your gender by the way), in England is 6ft for an adult it may differ in india and be only 5ft 6inches, (all examples none are studies/reseraches), so asking what is the average height is an invalid question to ask as there is no straight answers. This BMI calculator helps you to calculate your body mass index instantly.

However, weight, no there is a graph for that. If you feel that you may be overweight for your age/height then i will provide you with a BMI, (Body mass index), calculator. You use this to calculate what area you are in for example, Under weight/Over weight.
