Typography in CRO: High-Converting Type Guidelines for B2B

Last updated May 2026 · By Social Stardom

Typography Establishes Immediate Brand Trust

Website design often focuses on imagery and layout, but copy represents over 90% of your website. If your typography is difficult to read, has poor line heights, or uses generic default system fonts, it causes immediate cognitive fatigue and drives visitors away.

Typography Guidelines for High Conversion

To make your website copy clean, readable, and highly authoritative, apply these styling rules:

  • Pick Premium Sans-Serif Fonts: Use modern, highly readable sans-serif typefaces (like Inter Tight or Roboto) for B2B authority.
  • Optimal Line Heights: Maintain line heights of 1.5 to 1.65 for paragraphs to ensure comfortable, scannable reading.
  • Bold Visual Headings: Use heavy weights and tight letter spacing for headers to command attention instantly.

Topical Authority & Conversion Checklist

  • Verify Visual Contrasts: Ensure primary action buttons stand out instantly using bright, brand-aligned colors (like vibrant lime on deep black).
  • Audit Mobile Tap Targets: Set all checkboxes, buttons, and links to have an interactive tap target of at least 48px to meet WCAG standards.
  • Integrate One-Click Social Sign-Up: Minimize forms friction by implementing Google, Apple, and GitHub oauth logins to eliminate password fields.
  • Deploy Inline Input Validations: Validate email syntax and telephone formatting instantly in real-time to lower cart abandonment rates.

Frequently Asked Questions

Does typography affect conversion rates?

Yes. Clean, premium typography improves scannability, keeps users on your page longer, and establishes immediate brand credibility.

Should we use Serif fonts on B2B pages?

Serif fonts (like Instrument Serif) are excellent for high-end accent text and creative headlines, while clean Sans-Serif is best for body text.

What is the optimal font size for mobile body text?

Maintain mobile body text at a minimum of 16px to ensure readability on small screens without zooming.
