What should be the minimum height and weight to become a Model?

Height matter but not too much,but your physical apperance should be maintained. You attitude must be good.

As far as I know that the the standard height preferred is 5feet and 8 inches and weight somewhat 140 lbs and your age should be between 15 to 22 years...and your body condition should be fit and healthy...

There is no prescribed height or weight. The job requirements are: presentable personality, acting talent and passing screen test. What you appear onscreen is more signifcant.
