How do I know my body type?

Could someone please tell me which body type category I fall into? I thought I was slim thick, but after joining the slim thick sub, I noticed that the models there are more thicker than I am. I don’t think of myself as small; my ass is too huge and I am too tall. Should I just promote myself as slim? I have no idea if I am thin. Up until now, I didn’t consider myself to be thin—at least not in contrast to the kind of model that appears in publications. I would upload a picture of me standing up, but I’m not sure if that’s okay.
