This book documents the research process and methods behind Neutral, typeface that was constructed based on a set of parameters derived by measuring and averaging a number of popular 20th-century Sans Serif fonts. It consists of three parts: A explorative meditation on the subject of neutrality (with excerpts from discussions with with Daniël van der Velden, Experimental Jetset, Uwe Loesch, Bernd Kuchenbeiser and Helmut Schmid), the definition of a design method, the execution, comparisons and measurements.
