One of the coolest grids of all time is Karl Gerstner’s grid for Captial magazine. Based on subdividing a square into 58 equal units, Gerstner found he was able to make a grid of 2, 3, 4, 5, or 6 columns. It’s truly a thing of beauty. Designer Pedro Monteiro of the blog What Type recently retraced Gerstner’s steps, and, while he is not totally faithful to the original grid, his is certainly in the spirit of Gerstner’s, and he was nice enough to offer a PDF of his efforts here.
