I am 5'11", wear 30-31" inseam and 34" sleeves. I think I'm close to normal. In my upright-riding days, I had a 56cm bike, a 58cm would have gotten me in the nads. But that was before the 'compact' frames came along and all bikes had horizontal top tubes.
Edit: I'm wide through the shoulders (49" chest courtesy of swimming/diving into my 40s,) otherwise I'd be wearing 32' or 33" sleeves. Shoulder width doesn't count for frame sizing.
