Not really, you can find some guidelines like "your waist should be less than half your height", but things like average size of X body part, the data and people's perceptions are utterly fucked because 75% of people are fat. Even if you manage to find something like what you're talking about it will get dismissed like BMI because people don't like to admit they're fat when they're above average, men think they're just "big" and women think they're "curvy"
