1) American sizes are easy, the number about should be 72 dpi, so 8
inches = 8 * 72 = 576.
2) new A sizes are odd - they should be twice as big, but e.g the jump
from A2 to A1 increases by 1 mm (420 to twice that = 840 mm, but it is
841 mm?!?!).
In fact, A sizes are easy:
- A0 has an area of exactly 1 square meter.
- The ratio width:height is sqrt(2):1, so if you cut a landscape A(x) vertically in two, you get an A(x+1) with the same size ratio and half its area. What you have found are rounding errors.
