Who Wants the Dimensions of A Paper Sizes?

While researching standard A paper sizes for my latest Spaces for Ideas designs, I stumbled upon this great little site that contains this really clear and awesome diagram of how all the A paper sizes (A0, A1, A2, A3, A4, A5, A6, A7 etc.) relate to each other and how they came to be.

A Series Paper Sizes Defined

The A series paper sizes are defined in ISO 216 by the following requirements:

* The length divided by the width is 1.4142

* The A0 size has an area of 1 square meter.

* Each subsequent size A(n) is defined as A(n-1) cut in half parallel to its shorter sides.

* The standard length and width of each size is rounded to the nearest millimeter.

Not really industrial design related, but useful information nonetheless as I can’t remember the number of times I had figure out the paper sizes when setting up or sending drawings to the plotter. Don’t forget to copy the image or print it out and stick it somewhere convenient.
