How Poppins and Inter score across four checks — class contrast, role clarity, x-height harmony and mood affinity. Higher is better.
Inter is a neutral, screen-optimised grotesque built specifically for UI legibility, and under Poppins's geometric headings it recedes into clean, highly readable body text. The geometric-versus-grotesque difference is exactly the kind of structural contrast that gives an all-sans system real hierarchy, and their close tall x-heights keep the two in lockstep.
Where it shines
SaaS, apps, product and tech marketing — this is the modern startup sans-only system.
Keep a firm weight gap (Poppins 600+ headings, Inter 400 body) so the two neutral sans never blur into one another.
Add the fonts, then two rules — Poppins for headings, Inter for everything you read.
