It actually matters a good bit. Is this just something to have, or something that'll be used on something, say like a banner. Uniforms, or helmets, or something else entirely. Might not seem like it matters now, but when you go to a print company or whatever and say I have this 3" image I want on a 6' team banner... well, they're going to charge you to redo it more than likely. Just trying to help. If this is just for you to enjoy then, yeah, it doesn't matter what size it is I guess.
