Summarize:

Depending on what kind of modeling you plan on doing, i.e., print, runway, fit modeling, the ideal height and size measurements will vary. For print modeling, models are usually 5'8" and up, and are sizes 12 to 18. For high fashion or runway modeling, models are usually 5'9" and up, and sizes 10 to 20/22. For fit modeling, models are usually 5'5" to 5'9" and size 18. And for commercial modeling, models can be any height, and are sizes 12 to 18. Although these height and size measurements may seem rigid, there are always exceptions. If you don't fit these criteria, commercial modeling, fit modeling, parts modeling, and modeling for local and specialty boutiques are good alternatives. Models need to have healthy skin, hair, teeth, and nails. Plus sized models' bodies also need to be toned and in shape. Take care of your body by drinking plenty of water, getting regular exercise, and eating healthy. It is recommended that you drink eight 8 oz. glasses of water per day, i.e. 2 liters (0.53USgal) or half a gallon. It is recommended that you get either 150 minutes of moderate exercise or 75 minutes of vigorous exercise per week. Examples of moderate exercise are brisk walking and swimming. Examples of vigorous exercise are running. Or, aim for a combination of both moderate and vigorous exercise. Prioritize healthy fruits, vegetables, meats, and grains over processed foods, fast food, meats with a high fat content, and sugary foods. Having confidence is crucial to being a successful plus size model. You need to know your body shape, and you need to be comfortable with your body and its size. If you are uncomfortable with your appearance, it will show, and becoming a plus size model will be much more difficult. Be body confident by practicing positive self-talk. Remove negative self-talk, such as "I am fat" or "I am not good enough" with positive self-talk, such as "I love my body," "My body can do amazing things," or "I love my curves." Focus on the things that you love about yourself. Pick a body part; it could be your hands, breasts, thighs, or even your freckles. Then, talk out loud about that body part in a complementary way, such as "I love my thighs in these jeans." You can also focus on what your body parts allow you to accomplish versus how they look. For example, instead of talking about how bad or good your legs look, be grateful that your legs allow you to walk, exercise, dance, and can take you from place to place.
Know your height and size measurements. Take care of your body. Be body confident.
