Based on the Barbie mugshot meme.
Max and Chloe's heights are essentially canon (though for some reason Chloe's model is one inch taller than she should be, despite the height indicator being accurate). Chloe's weight is canon, Max's weight is a guess.
I mean characters aren't heterosexual by default. Sexuality is a matter of interpretation when it comes to fictional characters, and it is definitely possible to interpret Garak as pan or bi.
