Systematizing Prompt & Oxygen

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

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

Prompt thrives as a headline face thanks to its geometric, loopless, thai qualities. Use weights 700–900 for crisp editorial lockups.
Oxygen excels in paragraphs and UI thanks to its digital, linux, geometric traits. Keep it between weights 400–600 for optimal readability.
Hierarchy guidance: run a 1:1.2 modular scale and reserve Prompt for H1–H3 while Oxygen 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 Prompt can dramatize pull quotes while Oxygen keeps 1,500-word essays skimmable.
  • Conversion funnels or onboarding flows that need Oxygen's digital voice to balance Prompt's attention-grabbing display.

Accessibility Notes

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

CSS Implementation Cheatsheet

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

FAQs

Why does Prompt make sense as the lead font?

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

Where should Oxygen show up?

Oxygen is the workhorse. Keep it in paragraphs, long-form editorial, knowledge bases, or anywhere legibility is non-negotiable. Its digital, linux, geometric 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.
