Serif Fonts

Didone (e.g. Bodoni)

• Elegant, luxurious, sophisticated.
• High contrast and thin hairlines evoke exclusivity and refinement, commonly used by fashion and luxury brands.
• High-contrast strokes convey prestige but can sometimes reduce readability.

Correction: Extreme stroke contrast breaks down at small sizes, at low resolution, and at distance, because the hairlines are the first thing to disappear.

Transitional (e.g. Times New Roman, Baskerville)

• Classic, trustworthy, authoritative, professional.
• Ideal for brands seeking a balanced, credible, timeless feel.
• Commonly associated with tradition and reliability.

Addition, with a caveat attached: In a 2012 study: Readers shown a passage in Baskerville agreed with it more often than readers shown the same passage in Computer Modern, Georgia, Helvetica, Trebuchet or Comic Sans.

Cite it as evidence that typography touches credibility at the margin. Don't cite it as evidence that a typeface makes people believe you.

Old Style (e.g. Garamond, Caslon)

[New, 2026]

• Warmer and lower contrast than a Didone, less rigid than a Transitional.
• Reads as established rather than aspirational. Heritage without the fashion baggage.
• The low stroke contrast means it holds up at small sizes where a Didone falls apart, which makes it one of the few genuinely functional choices for long-form and body copy in a premium system.

Sans Serif Fonts

Neo-Grotesque

• Neutral, clean, professional.
• Conveys modernism, efficiency, and neutrality.
• Ideal for brands looking for clarity, accessibility, and universality.

Correction: Clarity and accessibility, yes. Universality, no. See the cross-cultural section at the bottom, which I've rewritten entirely because the original version of it was wrong.

Addition: Neutrality is a position, not the absence of one. A neo-grotesque says "we are not going to perform personality at you," which is itself a strong claim, and one that reads as either confidence or cowardice depending on what surrounds it.

Grotesque Sans Serif

• Robust, straightforward, industrial.
• Slightly warmer and more personality-driven than Neo-Grotesques.
• Used to communicate authenticity and strength.

Humanist Sans

• Warm, friendly, approachable.
• Humanist fonts evoke empathy and openness.
• Suitable for approachable, people-focused brands.

Addition:  Humanist sans faces carry more of the open, calligraphic curve of handwritten letterforms, and curved forms are preferred over angular ones at a level that shows up in basic visual preference research. Curvature also carries sensory expectation, which is the subject of the follow-up post and matters enormously if you sell something people put on their skin.

Geometric

• Modern, minimalist, futuristic.
• Associated with innovation, simplicity, and precision.
• Popular in technology, design, and fashion branding.

Script Fonts

Calligraphic

• Artistic, personal, elegant.
• Suggest refinement, creativity, and a human touch.
• Commonly used in premium or artisanal brands.

Handwritten

• Friendly, informal, authentic.
• Evokes warmth, approachability, and personal connection.
• Widely used in casual or personal branding.

Two conditions matter more than the headline finding:

The effect shrinks for brands people are already attached to. Handwritten type still creates human presence, but there's no additional attachment to gain. It's a tool for brands nobody feels anything about yet.

The effect reverses when the product is functionally positioned or functional in nature.

Slab Serif Fonts

• Strong, bold, authoritative.
• Associated with confidence, durability, stability.
• Often used by brands aiming for a dependable, impactful presence.

Addition: Weight is doing most of that, and weight has a documented commercial consequence. A delicate typeface symbolically carries light and thin. A bold typeface carries heavy and fat. The effect showed up specifically in consumers with a pronounced health-promotion focus, which is to say the people actively looking for a clean product.

Separately, visually heavier packaging raises price expectation. So slab pulls two directions at once. Heavier reads more expensive and less clean. If you're selling a barrier cream that positions on richness, that's aligned. If you're selling a lightweight gel and using a slab, your typeface is arguing with your product.

Decorative and Display Fonts

• Expressive, distinctive, attention-grabbing.
• Convey creativity, uniqueness, and personality.
• Ideal for impactful brand headlines or logos but can reduce readability if overused.

Correction: The cost isn't readability. It's that difficulty transfers. Applied: a routine set in a beautiful, effortful display face doesn't read as premium. It reads as a routine that will be hard to keep up.

And while we're here: hard-to-read type does not improve memory. Sans Forgetica, the typeface built and marketed on that premise, failed to replicate across four experiments with 882 participants and produced a memory cost in some conditions. It reliably makes people feel like they're concentrating. That's not the same thing, and the gap between those two is where a lot of bad design decisions live.

Monospaced Fonts

• Technical, structured.
• Suggest accuracy, efficiency, clarity.
• Commonly associated with coding, tech, and minimalist branding styles.
• Technical, structured, trustworthy.

Update: Monospace reads as machine-authored. Every character occupies identical width because a typewriter and a terminal have no choice, and we've learned to read that constraint as "a system produced this, not a person." That reads as accurate in contexts where system output is the credible source, like data, code, receipts, lab results. It reads as cold everywhere else.

Which makes monospace the exact opposite pole to handwritten. One maximises perceived human presence, the other eliminates it. If you know where a brand should sit on the human-to-machine axis, you've already narrowed the type decision considerably.
