How much do fashion models weigh?

Agencies ask that Female Models are no less that 5'11 and males, nothing under 6'0. If you are, you can be disadvantaged.

Your average healthy female model could range anywhere between 45-60 kilograms (usually in the height bracket of 5'8 or above). It really depends on other proportions in measurement. Measurements of proportions are also important. For example, Bust, Waist, and Hips. These are measured before a model can be accepted into an agency.
