A Runway Model: Most women on the catwalk are at least 5'8 and commonly small-breasted. Men are mostly between 5'11 and 6'2.
A Print Model: Most editorial female models are at least 5'7, but a beautiful face with great personality are the most important features for print models.
An Underwear Model: For women, this requires large breasts but small hips. For men, this requires broad shoulders but slim waists.
An Alternative Model: Some agencies hire alternative models: models who do not conform to the industry “standards” of beauty, height, and weight. Additionally, having a specific passion or cause that you're working towards can help open doors that may be closed due based on a body feature that does not “fit industry standards”.
Other Types of Modeling: If you don't fit any of the face or body descriptions, perhaps you can be a foot, hair, or hand model.
