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.
