The first rule of publishing a graph in a journal article is to make sure you’ve labeled your axes, and the first rule of publishing a photographic figure is to include a scale bar. Size matters, at least if you’re trying to accurately represent your data.

Which probably explains my fascination with visual depictions of size and scale. I’ve posted a few here over the years, beginning with the all-time great Powers of Ten by Ray and Charles Eames, along with star size comparisons, why context matters, and how flat maps depict size of spherical objects. Consider this another addition to the collection, the size of everything as defined through a sheet of A4 paper. How many folds does it take to get the paper down to the quantum realm? How many doublings to be bigger than our solar system? The answers await below.

5 Thoughts on "The Size of Things: As Told Through a Sheet of A4 Paper"

Nice video. I once successfully engulfed my scream while working inside a North-American standards institution, after hearing 2 people by my side mention “A4.” “What is it?,” one asked. “It is an EUROPEAN format,” replied the other. [INTERNATIONAL STANDARD,] repressed scream.
