Fonts to Use for English Posters: Practical Picks That Always Work

When you design an English-language poster, two things matter more than anything else: legibility from a distance and a clear typographic hierarchy (headline vs. body vs. captions). Below is a practical, low-risk font guide you can apply to academic posters, business posters, and event signage.


The simplest answer (a safe default pairing)

If you want a combination that rarely fails:

  • Headline: Helvetica / Helvetica Neue (fallback: Arial)
  • Body: Source Sans 3 or Inter
  • Charts & numbers: Use the same font as body for consistency, or Roboto if you want especially clean numerals

This setup works across most poster types because it prioritizes clarity, avoids stylistic “noise,” and prints reliably.


Recommended fonts by poster type

1) Academic and research posters (information-dense, readability first)

Best for: conference posters, lab posters, research summaries

  • Headline: Helvetica, Avenir Next, Montserrat
  • Body: Source Sans 3, Inter, Roboto

Why this works: Research posters typically contain more text and figures. A clean sans-serif body font stays readable at distance and at awkward viewing angles, which is exactly how people read posters in real venues.


2) Business and exhibition posters (brand presence, strong first impression)

Best for: trade shows, booth signage, product posters, corporate announcements

  • Headline: Gotham (alternative: Montserrat), Futura, Avenir
  • Body: Inter or Source Sans 3

Why this works: You can inject personality through the headline while keeping the body neutral and comfortable to read. This balance prevents the poster from feeling “designed” at the expense of clarity.


3) Elegant or premium look (use serif carefully)

Best for: luxury, art/culture events, premium branding (with controlled text volume)

  • Headline: Baskerville, Garamond, Didot (use with care)
  • Body: Keep it sans-serif (Inter, Source Sans 3, etc.)

Important caution: Serif fonts can look sophisticated, but serif body text often breaks down on posters—thin strokes can fill in or vanish depending on printing and viewing distance. A common safe approach is serif for the headline only, sans-serif for everything else.


Fonts to avoid (unless you have a very specific reason)

  • Comic Sans and Papyrus: they tend to reduce credibility in professional contexts
  • Thin/Light weights: they disappear in print and at distance
  • Decorative fonts for body text: high risk for legibility and tone mismatch

Practical typography rules (what professionals actually do)

Keep font families to a minimum

  • Use one or two font families max:

    • one for headlines
    • one for body text
  • If you need more variety, use different weights within the same family (Regular, Medium, Bold) rather than adding more fonts.

Use heavier weights than you think you need

  • Headlines: Bold to Black
  • Body: Regular to Medium Thin weights may look sleek on screen but often fail in real print settings.

Pay attention to numbers

Posters usually include:

  • dates, measurements, p-values, percentages, axes, and legends Fonts like Inter and Roboto handle numerals well. If available, consider enabling tabular figures (monospaced numerals) for charts and tables so columns align cleanly.

Choose fonts that export cleanly

Your toolchain matters:

  • PowerPoint and Canva benefit from widely available fonts
  • Illustrator/InDesign workflows often allow more flexibility For final output, many teams embed fonts or convert text to outlines to prevent font substitution.

A short checklist before you finalize

  • Can the headline be understood from several meters away?
  • Is the body comfortable to read at 1–2 meters?
  • Are captions and figure labels still legible when printed?
  • Are you using no more than two font families?
  • Are you avoiding Light/Thin weights?

If you can answer “yes” to these, your typography will look professional in almost any setting.
