How to Choose the Right Font for Your Presentation

Font choice is one of the highest-leverage design decisions in a presentation. The wrong font makes slides harder to read, undermines your credibility, and signals to the audience that you did not sweat the details. The right font does the opposite — it disappears, letting your content carry the room.

The Two Font Categories You Need to Know

Every presentation needs at most two typeface categories: a display font for titles and headers, and a body font for bullet points, captions, and supporting text. You rarely need more than this combination, and introducing a third face usually creates visual noise rather than variety.

Display fonts can have more personality — a heavier weight, a slight serif, or a condensed form. They are read at a glance, not scanned line by line, so legibility at small sizes is not the primary concern.

Body fonts must be clean and highly legible at 18–24pt on screen. Sans-serif faces dominate presentation body copy because they render more crisply on screens than serif fonts, which need high-resolution print to show their advantage.

Fonts to Use

For corporate and professional decks:

• Titles: Inter Bold or Calibri Bold
• Body: Inter Regular or Calibri Regular
• Alternative title: Neue Haas Grotesk Display

For startup and tech decks:

• Titles: Plus Jakarta Sans Bold or DM Sans Bold
• Body: Plus Jakarta Sans Regular

For creative agencies and design-led decks:

• Titles: Playfair Display Bold (serif contrast creates a premium feel)
• Body: Source Sans 3 Regular

For education and training decks:

• Titles: Nunito Bold
• Body: Nunito Regular or Open Sans

Fonts to Avoid

• Comic Sans — universally signals low effort
• Papyrus — visual cliché
• Times New Roman — reads as an unstyled Word document default
• Decorative display fonts for body text — ornate faces are illegible past two lines
• More than two typefaces — creates visual chaos rather than hierarchy

The Size Rule

A common mistake is setting body text too small. On a 16:9 slide displayed on a 1080p screen:

• Title text: 36–48pt
• Subtitle or secondary headline: 28–32pt
• Body bullet text: 20–24pt
• Caption or footnote: 16–18pt

Below 18pt, text becomes unreadable for anyone past the third row of a conference room. When in doubt, bump the size up and cut words.

System Fonts vs. Web Fonts

If you are building slides in a web-based tool like Slide-deck.io, Google Slides, or Canva, you have access to web fonts (Google Fonts and similar). If you are building in PowerPoint and sharing the file across machines, stick to fonts that are universally installed (Calibri, Arial, Georgia, Trebuchet MS) or embed the font in the file. Sending a PPTX with a custom font to someone who does not have it installed will cause silent substitution — your carefully chosen face becomes Arial.

Pairing Logic

Good font pairings share one quality and contrast on another. Pair two weights of the same family (Inter Light + Inter Bold), or pair a serif display with a sans-serif body (Playfair Display + Source Sans). Avoid pairing two decorative fonts — they compete rather than complement.

One Practical Test

Set your title at 44pt and your body at 22pt. Stand three meters from your monitor. If you cannot read both without squinting, either the font size or the font choice needs to change. This simulates what the back of a conference room looks like, which is where the most important people in your audience often sit.

Summary

Pick one font family, use two weights, keep body text above 20pt, and test readability at distance. Typography in presentations is less about personality and more about removing friction between your ideas and your audience.
