How oodles A4 page is equal to an nouns of A1?

it go that way:

1 A3 = 2 A4

1 A2 = 4 A4

1 A1 = 8 A4
The scale goes approaching this: A4 X 2 = A3 X 2 = A2 X 2 = A1 X2 = A0



Thus A1 has 8 times the nouns of A4.
I hate to disagree but the following are the sizes:



A1 594 × 841

A2 420 × 594

A3 297 × 420

A4 210 × 297



Paper within the A series format has a 1:\sqrt{2} aspect ratio, although this is rounded to the nearest millimetre.



A4 is close to a quarter the size of A1 but here is a slight difference.
8
