Systematizing Questrial & Source Sans Pro

Build a mono-category system where Questrial leads and Source Sans Pro keeps long-form content legible.

This pairing is engineered for teams that need a clear hierarchy without sacrificing brand voice. Questrial brings geometric, modern, clean energy to hero units, pricing sections, and campaign headlines. Source Sans Pro absorbs the heavy lifting for paragraphs, product storytelling, and UI labels with its ui-focused, legible, adobe texture and dependable rhythm. Together they create a typography stack that scales from high-impact landing pages to dense documentation without retooling your CSS tokens.

Questrial thrives as a headline face thanks to its geometric, modern, clean qualities. Use weights 400–600 for crisp editorial lockups.
Source Sans Pro excels in paragraphs and UI thanks to its ui-focused, legible, adobe traits. Keep it between weights 400–600 for optimal readability.
Hierarchy guidance: run a 1:1.2 modular scale and reserve Questrial for H1–H3 while Source Sans Pro powers captions, body copy, and data tables.

Best-Fit Use Cases

  • High-growth SaaS landing pages that require geometric hero statements with trustworthy product copy.
  • Editorial magazines and thought-leadership hubs where Questrial can dramatize pull quotes while Source Sans Pro keeps 1,500-word essays skimmable.
  • Conversion funnels or onboarding flows that need Source Sans Pro's ui-focused voice to balance Questrial's attention-grabbing display.

Accessibility Notes

Maintain a minimum 4.5:1 contrast ratio for Source Sans Pro body copy and loosen letter-spacing to 0.01em for uppercase Questrial moments. Pairing different categories demands disciplined color pairing—test both light and dark themes to ensure Source Sans Pro does not bloom at small sizes.

FAQs

Why does Questrial make sense as the lead font?

Questrial owns the emotional register of this system. Its geometric, modern, clean profile helps anchor campaign creative, meaning marketing and product teams can reuse the same voice without reinventing the scale.

Where should Source Sans Pro show up?

Source Sans Pro is the workhorse. Keep it in paragraphs, long-form editorial, knowledge bases, or anywhere legibility is non-negotiable. Its ui-focused, legible, adobe qualities reduce fatigue on dense layouts.

Does this pairing support complex localization?

Yes—both families are available on Google Fonts with generous glyph coverage. Test cyrillic/latin accents early, but most Latin-based locales and UI patterns are fully supported.
