The lowercase runs from Tinos, the shortest at 459 units per 1,000 em, to Open Sans at 535. In width, Tinos is the narrowest (459) and Cousine the widest (600). Beyond Latin, the families cover eight subsets: Cyrillic, Cyrillic Extended, Greek, Greek Extended, Hebrew, Math, Symbols, Vietnamese. Measured against the medians of their own classes, three of the four families with ascenders have a taller x-height, two of all four set a wider lowercase and two a darker one.
