"Metric is an attempt to temper the geometric tendencies of the engineer by the hand of the typeface designer. The letterforms in Metric & Calibre are, of course, optically corrected. I’ve tried to keep it as subtle as possible, I wanted letterforms that felt monoline, rational and unpretentious. Like the street sign letterforms that informed the development but without the shortcomings inherent to strict geometry."
