Systematizing Castoro & Average

Build a mono-category system where Castoro leads and Average keeps long-form content legible.

This pairing is engineered for teams that need a clear hierarchy without sacrificing brand voice. Castoro brings text, academic, readable energy to hero units, pricing sections, and campaign headlines. Average absorbs the heavy lifting for paragraphs, product storytelling, and UI labels with its text, neutral, readable 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.

Castoro thrives as a headline face thanks to its text, academic, readable qualities. Use weights 400–600 for crisp editorial lockups.
Average excels in paragraphs and UI thanks to its text, neutral, readable traits. Keep it between weights 400–600 for optimal readability.
Hierarchy guidance: run a 1:1.2 modular scale and reserve Castoro for H1–H3 while Average powers captions, body copy, and data tables.

Best-Fit Use Cases

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

Accessibility Notes

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

CSS Implementation Cheatsheet

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

FAQs

Why does Castoro make sense as the lead font?

Castoro owns the emotional register of this system. Its text, academic, readable profile helps anchor campaign creative, meaning marketing and product teams can reuse the same voice without reinventing the scale.

Where should Average show up?

Average is the workhorse. Keep it in paragraphs, long-form editorial, knowledge bases, or anywhere legibility is non-negotiable. Its text, neutral, readable 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.
