The typefaces that ship with psi-slides

Nine faces for the text

Nine faces in three roles: five serifs, two sans faces and two monos. Literata, IBM Plex Sans and JetBrains Mono are the default and need no line in the frontmatter. A deck embeds one face per role, 279 KB in each view for the default three. Pick one per role to see the pairing on a slide and on a page of the handout.

Each one fills a role. On a slide the serif sets the heading and the prose, the mono sets code, and the sans sets the slide number and the labels in a figure; on the printed page the sans also sets the type word and the caption. During a talk, F switches the slide text between the deck’s serif, its sans and its mono, and Shift F back again – the three faces the deck already carries, in the projection and the speaker view at once. font: sans in the frontmatter says which of the three a lecture opens in.

In the frontmatter: nothing, the default three need no line · 279 KB of type in each view.

32 faces for a title slide

A cover, a closing slide and the section dividers are the one place in a lecture where a loud typeface is not a mistake. These are the faces that ship with the tool for that job, each one drawn into a real cover and a real divider, with the title you type into it.

fonts: {display: Anton} in the frontmatter is the whole of it, and it reaches those three slides and nothing else – an ordinary heading, a card lead, a figure label all keep the body type. What the role does is on the decoration page.

They come in three kinds: 6 hand, 8 machine and 18 graphic. Median 21 KB each, 824 KB for the whole set, but a deck embeds one of them: the figure on a card is what naming that face costs a lecture in every view.

Four numbers decide most of these, and they are on every card. The kind is the pairing rule: a display serif is drawn here over a sans body and a display sans over a serif body, because a display serif over the deck's own serif reads as one typeface set badly rather than as two – lint.js warns when a deck does the opposite. The percentage is that face's measured advance width against the body serif, emitted as a size-adjust descriptor: these faces disagree about width by a factor of three, and without it Press Start 2P simply ran off the slide. The KB is the payload. A no ß badge means the face has no eszett and a German title gets a fallback glyph mid-word; exactly one face here does.
