It depends on your definition of "ideal size for a wrestler". Go to Mexico, or Japan for example. Look at the rosters of the New Japan, All Japan, AAA, and CMLL and tell me what do you see. Lots of "cruiserweights/light heavyweights". Reason being is the culture for the Luchadore and Purseau types of wrestling are higher in the spotlight for those types of wrestlers. In the USA, WWE in particular, look at the list of WWE/World Heavyweight Champions. Most of those champions, better yet, 90% of those champions were Heavyweights. Sure, Mysterio, Punk, Jericho, Benoit weren't heavyweights, but look at the rest of those champs. Cena, Angle, Big Show, Andre, Savage, Hogan, Kane, Undertaker, Edge, Brock Lesnar, Botchista etc. So to answer the question, I would say it truly depends on what promotion you are in and what country you wrestle in because the "size" aspect differs from country to country and promotion to promotion. But if it was up to me, size really wouldn't make that big of a deal to me. I would rather look at in-ring ability, mic skills, athleticism, and overall character. To me that is much important realistically. However after those traits, I'd honestly would think that the ideal size if wrestlers were working for me is anywhere from 6'0-6'7 and weigh about from 220-270 or so. The numbers may be a little off but i'd say 6'4 245 would be ideal honestly.
