So the next paper size is the double of itself and each paper size gets bigger.

Easiest way to remember the sizes is do like Americans. 3x5, 8x11, 4x6, etc.

[@Obsidian_Iris_]

They aren’t equivalent. Close in some cases, but not the same. This is the worldwide standard, so it is worth remembering.

We all know that but what are the sizes ?

[@TS-qq7vr]

A4 is what we call 8 by 11.

[@puhnpicker]

Absolutely worthless. You miss the big idea: design a system whereby, after folding a sheet of paper in two parts, the ratio between length and width remains the same. I you have a sheet y cm by 2x cm, make the dimensions as follows: y/2x = x/y. Or 2.x squared = y squared, which gives y/x = square root of 2. This root 2 is the secret of this system !

[@Mobilefish]

Hans, you are right but that is not the point I am trying to make. If I am holding a A4 paper in my hand I can easily imagine what the size is of an A2 paper. That’s the point I am trying to make!

[@TS-qq7vr]

Who use such huge pieces of paper?

[@pelemlangka]

Where is the A5 size?

[@Mobilefish]

Fold A4 paper over the long side and you will get A5

[@crono7817]

Where is a5?

[@Mobilefish]

That is A4 folded
