Eharmony and various other dating sites actually, BY DEFAULT, will only match women with men taller than them. Anyway, none of the major ones even have weight at all, and the "Body Type" descriptors are a joke. Online Dating really sucks for men... best is to meet people in meetups, volunteering, clubs, church, ect. You can instantly see if people are far or not. Of course, women can still be catfished in online dating, but men seem to be much less knowledeable of how to hide the fact that they are fat in profile photos.
