Why it works

A true superfamily pairing: Frank Grießhammer drew Source Serif at Adobe specifically to complement Paul Hunt's Source Sans, matching its x-height, weight distribution and vertical metrics. That shared skeleton means headings and body align optically with zero friction, while the serif's Fournier-inspired details add editorial authority the sans deliberately withholds. Ideal when you want serif gravitas without any pairing risk.
