Calfonts: italics that aren’t just slanted romans
Italics are the part of a font family that most often gets shipped wrong — slanted romans, no cursive structure, lopsided ovals. The Calfonts italic tutorial walks through what it actually takes to draw an italic that earns its place next to the roman.
What the italic is for¶
Italics do four jobs in real text:
- Emphasis. Marking a word or phrase as important within roman text.
- Titles. Book titles, ship names, foreign words.
- Voice change. Inner monologue, quotation, stage direction.
- Hierarchy. Distinguishing one level of a document outline from another.
All four require that the italic look distinctly different from the roman at the same size. A 12° slant is not enough to do that. The italic has to be structurally different.
The structural changes that make an italic¶
Single-storey a and g. This is the single most-recognizable italic feature. The two-storey a and g are roman conventions; cursive a is a single bowl, cursive g has a single bowl with a tail.
Narrower lowercase. Italic letters are 5–10% narrower than their roman counterparts at the same size. Same x-height, same cap-height, less width. The texture of italic text is denser, which is part of how it reads as different from roman.
Cursive entry and exit strokes. i, n, m, r, u start with a small upstroke from the baseline. e, i, n, m end with a small upstroke into the next letter. These are vestiges of pen-on-paper writing, and they are what gives italic text its rhythm.
Tipped contrast axis. A broad-edged pen held at 40–50° (vs the roman 30°) produces a different stress on round letters. The thicks and thins move. Designing italic without thinking about the contrast axis produces ovals that are heavier on the wrong side.
Drawing the italic¶
The Calfonts approach: draw the italic lowercase at 0° slant first. Get the structure right — single-storey letters, cursive strokes, narrower widths, correct contrast axis. Then apply slant as a transformation, usually 8–14°.
Doing it in the other order (slanting first, then trying to fix structure) almost always produces a worse result. The slant disguises structural problems just enough to make them hard to find.
The capital question¶
Italic capitals have less leeway. They are usually slanted versions of the roman caps with mild structural touches — narrower proportions, sometimes a different Q tail or J foot. Full cursive capitals (swash caps) are a separate design layer, usually accessed through swsh or salt features.
Verification¶
Set the italic next to the roman at text size — 9 to 11 point — and read a paragraph. The italic should look like a sibling of the roman, not a tilted twin. If the slant feels like a transformation rather than a design, something in the structure is still wrong.
