Pairing Strategy

Balancing Assistant with Castoro

Build a contrast-first system where Assistant leads and Castoro keeps long-form content legible.

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

Assistant thrives as a headline face thanks to its hebrew, clean, simple qualities. Use weights 700–900 for crisp editorial lockups.
Castoro excels in paragraphs and UI thanks to its text, academic, readable traits. Keep it between weights 400–600 for optimal readability.
Hierarchy guidance: run a 1:1.4 modular scale and reserve Assistant for H1–H3 while Castoro powers captions, body copy, and data tables.

Best-Fit Use Cases

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

Accessibility Notes

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

CSS Implementation Cheatsheet

:root {
  --tm-header-family: 'Assistant', sans-serif;

  --tm-body-weight: 400;
  --tm-header-tracking: -0.01em;

}
Heading scale: clamp(2.75rem, 4.5vw, 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 Assistant at 700 for momentum, while forms, tables, and footnotes stay on Castoro with 400 weight for predictable kerning.

FAQs

Why does Assistant make sense as the lead font?

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

Where should Castoro show up?

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