To change the size simply multiply the
sizes equally. Example to make 425 twice as big you change it to
850. The example below has been shrank by half. It's not exact.
Just keep your number whole.122.80 would be 123 and 245.89 would
be 246 It's not that hard. If you're off by a number or 10 it
doesn't matter much. Just leaves a black border on top or bottom
if you haven't divided equally
