so?

who had biggest arms relative to own height,if anyhting
It's harder to have thicker arms when your limbs are longer and you're taller. Soo.. technically yes Kovac has the biggest arms in history of BBing.
18" arms on a 5'8 guy vs a 6'3 guy.. The 6'3 guy has to have more mass for his longer limbs to make that size. The shorter guy has shorter limbs which means his muscles are stretched less than the taller guy therefore it's easier for him to appear and be thicker.
