There may be size differences, even amongst similar colors. We don't have information on each size for each color, so there's missing info on this sort of thing. There's also a chance that the balls you have aren't Nerf-branded? Unless you got them from an old refill pack.

That article could use some rewrites, honestly, so if anyone has any measurements or information on the subject, that'd be great.
