6'2 male Thai boxer here:  I used to fight at 170. I walk around at 205 and my last fight I weighed in at 178 and my actual fight weight was probably closer to 185.  I've moved up a weight class and will be fighting at 185 going forward. I'm a pretty big dude compared to the average and I'm a full foot taller than her and my fight weight is roughly her every day weight.
