Range of the work

The lowercase runs from Roboto, the shortest at 528 units per 1,000 em, to Roboto Slab at 528. In width, Roboto Condensed is the narrowest (441) and Roboto Mono the widest (600). Beyond Latin, the families cover seven subsets: Cyrillic, Cyrillic Extended, Greek, Greek Extended, Math, Symbols, Vietnamese. Measured against the medians of their own classes, four of the four families with ascenders have a taller x-height, two of all four set a wider lowercase and four a darker one.
