emblems

So, I am getting ready to paint the front and rear emblems (at least the ones I can't take off completely b/c of holes) on my Black mica '07 3, and want to get some general opinions. My original thought was to paint em flat black and then do a top coat of clear. I was going to do a top clear...

I have used the search button, but found nothing relevant to the info of what exactly I'm looking to discover. I would like to know the sizes of the badges/emblems on the front and rear of P5's. I would just measure mine, but how are they measured? Left to right, width? Or top to bottom...
