Why it works

Plex Sans and Plex Serif were drawn together by Mike Abbink and Bold Monday on shared skeletons and identical vertical metrics, so mixing them is less a pairing than two voices of one typeface. The grotesque headings carry IBM's engineered neutrality; the serif body adds a journalistic, almost typewriter-adjacent warmth to running text. The result feels rigorous and bookish at once — well suited to research writing, case studies and technical publications.
