Pairing Strategy

Balancing Fira Mono with Sarabun

Build a contrast-first system where Fira Mono leads and Sarabun keeps long-form content legible.

This pairing is engineered for teams that need a clear hierarchy without sacrificing brand voice. Fira Mono brings mozilla, coding, clear energy to hero units, pricing sections, and campaign headlines. Sarabun absorbs the heavy lifting for paragraphs, product storytelling, and UI labels with its thai, document, formal 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.

Fira Mono thrives as a headline face thanks to its mozilla, coding, clear qualities. Use weights 700–900 for crisp editorial lockups.
Sarabun excels in paragraphs and UI thanks to its thai, document, formal traits. Keep it between weights 400–600 for optimal readability.
Hierarchy guidance: run a 1:1.4 modular scale and reserve Fira Mono for H1–H3 while Sarabun powers captions, body copy, and data tables.

Best-Fit Use Cases

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

Accessibility Notes

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

FAQs

Why does Fira Mono make sense as the lead font?

Fira Mono owns the emotional register of this system. Its mozilla, coding, clear profile helps anchor campaign creative, meaning marketing and product teams can reuse the same voice without reinventing the scale.

Where should Sarabun show up?

Sarabun is the workhorse. Keep it in paragraphs, long-form editorial, knowledge bases, or anywhere legibility is non-negotiable. Its thai, document, formal 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.
