Okay, I make it 103mm in width across the middle. The little square is 32mm from top to bottom.
Thanks for that, so my "lookie likie" ones are quite close to the real thing, I'm still very tempted just to order up the real thing though.
One other thing that I had thought about was to fit one of these badges (the real ones) just below the S4 logo on the boot lid and stagger it so that the "red square" is below and to the right of the S4 one, just a thought, though I can't do that with the "lookie likie" ones as the red is a different colour!
My car is deep sea blue, I'm sticking with the RED and black badges.
