If models can be fat then why cant they be short?

Answer 1

It is not appropriate to call larger models "fat." In the modeling industry they are referred to as plus size models. Although they wear a larger dress size, they are still required to maintain strict measurements and must still be tall (5'8"-6'0") like traditional fashion models.

There are short models, mainly in commercial/print modeling (5'5"-5'7") as well as petite modeling (5'0"-5'7"...many in the industry consider anyone under 5'7" to be petite). Unfortunately, there is no demand in the market for petite models, which is why it is much harder for models in this field to find work. Right now the demand is for plus size models, which reflects the growing trend of women's dress sizes getting larger, hence the need for the appropriate kind of models. Short models exist, they are just not in demand at the moment.
