YOU CAN MEASURE most things in the physical world with centimeters and inches. A standard ruler handles both—but it ignores digital environments, which render in pixels, and typefaces, which print in picas.
Designers who work with all four units either excel at mental math (a 12-point font is one pica, or 0.167 inches, tall), or, more likely, own a bunch of rulers. “I used to have five,” says Axel Lindmarker, a student at the School of Visual Arts in New York. Too many, he thought. So, along with fellow student Jens Marklund, he designed one rule to rule them all. They call it the Lindlund (Lind__marker + Mark__lund). Inches and centimeters run along its outer edges, pixels and picas along the narrow rectangle that cuts through its middle.
