The fingers on my left hand are from index to pinky, 2.5", 3", 2.5" and 2". I am 6' tall, but it comes from my torso, as I have short legs and arms for my height.
I have a 34" scale bass currently, 4 and 5, and I played a 35" scale 5 string ESP as a young adult in my early 20s. I can play a 27" scale 8-string Ibanez guitar. I have worked at a computer since 1999, and played the **** out of MMORPGs in my early to mid 20s, and I write literature as a hobby.
A standard 6-string is beyond me, but otherwise, game on! I'm always stretching/twisting my wrists, though, and keeping them nice and limber and feeling good.
I will say that Schecter Stilettos are a lot more comfortable for me sitting down, as I progress up the neck. I can rest them on my left leg instead of the right so I get a better angle. +eleventy billion for straight-wrist technique.
