Few people are aware that the A4 sheet that makes life easier for millions of people every day is a German invention.
Today, it is hard to imagine a society without standardised formats for paper and envelopes. A society where the choice of paper format was made entirely according to taste and preference and without the slightest consideration for compatibility or efficiency. A society where a plethora of file formats, folder sizes and printer and copier adjustments had to work alongside.
The A format was invented in 1922 by Dr Walter Porstmann, was registered as standard no. 476 "Papierformate" and quickly spread all over the world. The rest is history.
