Mr.Bernoulli:
I'm glad to hear your are not printing them on illegal paper!
Prefer A4 myself!
We can't get A4 over here in the colonies.
In any case, what our legal system forces us to call "legal size" at 8.5 x 14 inches works better than your A4 for Jepp approach charts. Even Granny can read them on legal stock. (The small drawback is you can't see the instrument panel while you are reading the lawful-size chart.)
