This pairing is engineered for teams that need a clear hierarchy without sacrificing brand voice. Cairo brings arabic, modern, titling energy to hero units, pricing sections, and campaign headlines.

Pairing Strategy

Systematizing Cairo & Prompt

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

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

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

Best-Fit Use Cases

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

Accessibility Notes

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

CSS Implementation Cheatsheet

:root {
  --tm-header-family: 'Cairo', sans-serif;
  --tm-body-family: 'Prompt', 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 Cairo at 700 for momentum, while forms, tables, and footnotes stay on Prompt with 400 weight for predictable kerning.

FAQs

Why does Cairo make sense as the lead font?

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

Where should Prompt show up?

Prompt is the workhorse. Keep it in paragraphs, long-form editorial, knowledge bases, or anywhere legibility is non-negotiable. Its geometric, loopless, thai 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.
