Systematizing Muli & Cairo

Build a mono-category system where Muli leads and Cairo keeps long-form content legible.

This pairing is engineered for teams that need a clear hierarchy without sacrificing brand voice. Muli brings minimalist, invisible, clean energy to hero units, pricing sections, and campaign headlines. Cairo absorbs the heavy lifting for paragraphs, product storytelling, and UI labels with its arabic, modern, titling 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.

Muli thrives as a headline face thanks to its minimalist, invisible, clean qualities. Use weights 700–900 for crisp editorial lockups.
Cairo excels in paragraphs and UI thanks to its arabic, modern, titling traits. Keep it between weights 400–600 for optimal readability.
Hierarchy guidance: run a 1:1.2 modular scale and reserve Muli for H1–H3 while Cairo powers captions, body copy, and data tables.

Best-Fit Use Cases

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

Accessibility Notes

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

CSS Implementation Cheatsheet

:root {
  --tm-header-family: 'Muli', sans-serif;
  --tm-body-family: 'Cairo', sans-serif;
  --tm-header-weight: 700;
  --tm-body-weight: 400;
  --tm-header-tracking: -0.01em;
  --tm-body-tracking: -0.005em;
}
Heading scale: clamp(2.75rem, 3.6vw, 5.25rem) for H1, clamp(1.5rem, 2.8vw, 3rem) for H2, and keep paragraph size at 1rem–1.125rem with 1.6 line-height.
Component guidance: Buttons inherit Muli at 700 for momentum, while forms, tables, and footnotes stay on Cairo with 400 weight for predictable kerning.

FAQs

Why does Muli make sense as the lead font?

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

Where should Cairo show up?

Cairo is the workhorse. Keep it in paragraphs, long-form editorial, knowledge bases, or anywhere legibility is non-negotiable. Its arabic, modern, titling 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.
