Why these typefaces

Three families, three jobs, and the flexibility of variable type.

The system needed a serif voice for judgment, a plain sans for long passages, and a monospace for labels and data, without the three competing for attention.

I also wanted variable typefaces. A variable font holds a range of weights, and sometimes optical sizes, in one file, so each use can be tuned instead of picked from a short list of fixed styles. That flexibility is what lets one system cover a hero headline and a 48px avatar.

A serif built for reading on screens, with an editorial voice.

Newsreader was designed by Production Type for on-screen reading, and it carries the feel of a well-made magazine. I trust the foundry's craft, and it shows in how the type holds up at every size.

It works from an avatar to a hero headline because it has an optical-size axis: the letterforms adjust for the size they're set at, sturdier when small and more refined when large. That's why one family can carry the wordmark, the headlines, and the metric figures.

Neutral on purpose, so the serif and the numbers stay loud.

The body sans has one job: stay out of the way. Hanken Grotesk reads cleanly at body size, so a reader gets through a case study without noticing the type, and its plain, even letterforms sit comfortably next to Newsreader.

Choosing it this way, by reading it rather than reaching for a familiar name, is the habit my research is about. In the Type Default Audit, I asked three AI model families to recommend typefaces 1,890 times. They named 1,029 typefaces, and about 40 of them carried half the answers. Defaults are where tools, and people, go without thinking. Every family on this site was chosen by setting it and reading it.

The details get their own voice.

In this system, monospace marks metadata: a label, a date, an index, a source. Spline Sans Mono is a humanist monospace rather than a coding-terminal face, so it carries that signal without reading as developer tooling, and it keeps its personality at the small sizes where labels live.

It's used only small and uppercase. That restriction is deliberate: once mono shows up in a paragraph, it stops signaling anything.

Contrast by family, not by weight.

Hierarchy comes from three clearly different voices at a small number of sizes, rather than many weights of one family. A heading, a paragraph, and a label are easy to tell apart at a glance, and the variable axes let each be tuned for where it appears.
