Jim,
Just a thought.
I took my ruler out and tried to visualize a 2 by 10 inch logo to stick on the windshields.

My opinion is that while that might be the right size for the back of the jackets, it seems very small for the windshields.
Others may feel differently. That is smaller than one of the visors.

For height I recommend minimum 3", if not 4". Thus making the overall length 15" or 20".

What do you guys think?
