I used to ride with a group that included a bike with a 2 letter. 2 number plate. 100% legal, but really very small!
For cars there is no specified legal size other than an absolute minimum margin of 11mm producing, a font height 79mm and a width of 50mm, the margins must be 11mm all round.
So for a 2 letter 2 number the width would be 272mm and the height of 101mm.
I would love PJ 52, but I wouldn't pay the silly monies asked!.
