Of course. I forgot its from finger tip to finger tip. But only up to the knuckles counts in any significant way.
Having said that, you're exaggerating somewhat. To say Bones fingers go another 6 inches off the bottom of the image is a lot. Even if correct, ITs not like Gus stops there. And, as I said, Gus shoulder is clearly higher then Bones. I'll stick by my guns. I believe Bones arms are each at most one inch longer. Also, to say his shoulders are much more broad? Really? It looks marginal to me. Even to the point where I put the image in photoshop and measured the distance from the middle of the neck to the left shoulder. Bones is no wider then Gus going by the pic. If anything, Gus was a few pixels wider.
Going by the pic, of course. Not saying anything is fact. But going by the pic, Bones is absolutely not much longer then Gus.
Not exaggerating at all. From what I can see the pic stops BEFORE Bones knuckles. Looking at my fairly average hands my middle finger is about 4 inches. Bones is a 6'4 black dude who's brothers play football. His hands are probably huge. Half foot more is actually on the low side in my opinion. Bones probably has way bigger hands than Gustaf. And we will see come fight time. But I am always amazed at how big Bones actually is on fight night.
