What is the ratio of a A4 paper sheet? I don't have

210 x 297 mm
Should be a ratio of ~1.414
What is this for, anon?

1/sqrt(2)

That's the whole point and beauty of the DIN A format. if you take a DIN A sheet and halve it in the middle, the two resulting sheets have the exact same ratio again- they are now simply one number bigger (e.g. din A4 --> din A5). At the same time the area can be extremely easy calculated- DIN A0 has 1 m2, just divide by the A-number of your sheet.

>>275831

*divide by 2^n with n being the A-number of your sheet
