Thanks for the answer.

Filippo
A4 portrait is 210mm X 297mm (width X height)
A3 portrait is 297mm X 420mm

The sides (long/short) are in the proportion of a:1 where a = the square root of two, which is approx. 1.414213562.

The long side of A4 = the short side of A3 and this relation continues through all of the DIN Ax sizes. So, the new scale would be 1:(350 divided by the square root of two) which would be approx. 1:247.487373415.
