Such large typeface families are quite popular for their ability to meet the requirements of complex typographic tasks, and for their matching counterparts which negate the need to find appropriate pairings from other typefaces.
While most body text faces often are a bit too delicate, Expo Serif’s stroke width is robust enough to perform well in a broad range of uses. It’s an elegant workhorse that is highly legible in extensive texts without becoming obtrusive yet still maintains its own character. Four suitable weights and their italics are included: Light, Regular, Semibold, and Black.
What also makes this family special is not only the broad language support but the huge amount of OpenType features in all styles with which you can handle complex typographic jobs: small caps, swash caps, four figure sets, superscripts, subscripts, numerators, denominators, fractions, and a full range of ligatures, historical forms, and ordinals.
Mark Jamra knows his craft. He designed one of the best bibliophilic typefaces of the year. As if this wasn’t enough, he just gave Expo Sans a Pro upgrade as well for a even better pairing.
