How big must I be to fit into a Superman costume for Halloween?

I want to be Superman for halloween. I am 6 ft, 160 pounds right now...I am wondering how big Christopher Reeve, Dean Cain, or the last Superman must have had to be to fit into the costume.|||The ideal size would be around 165lbs. and 6ft.2inches...so you are right on the mark...up up and away!!!|||Does it matter? They come in all sizes...|||if you got it, flaunt it|||I would suggest that you rent a costume that fits you, and not the other way around.|||Depends on what size costume you buy, man. There's not one set size for the costume, I'm sure you could find one that would fit you.
