The download menu is part of the design
Iosevka 34.9.0 offers separate packages for code editors, terminals, and quasi-proportional documents. The official README lists six monospace subfamilies. Each combines a sans or slab design with Default, Term, or Fixed spacing. Aile and Etoile cover quasi-proportional text.
A terminal font and an editor font can share a name while keeping different spacing promises.
Term narrows arrows and geometric symbols to fit terminal columns. Fixed goes further. It removes wide glyphs and disables ligatures for stricter compatibility. That difference matters when a prompt, diff, box drawing character, or table must stay on its expected cell.
Density is a test, not a trophy
The project describes its standard monospace glyphs as one half-em wide. That can put more code on screen. It can also make iIl1|, 0O8B, braces, punctuation, and operators harder to parse at your normal zoom.
Road-test the real pane width and font size. Include a diff, an error trace, nested punctuation, non-ASCII identifiers, and any box drawing used by your terminal tools. Check upright, italic, and bold text. A specimen page cannot reproduce your renderer, hinting, display scale, or theme.
Customize after the baseline survives
Iosevka exposes stylistic sets, character variants, ligation sets, two monospace widths, nine weights, and three slopes. Its custom build file can set the family name, spacing, serif style, ligation policy, and webfont formats.
Start with a release package. Save the exact version and package name. Change one choice at a time. If you build a custom family, give it a distinct name and keep the build plan beside your editor settings. That turns a visual preference into a setup another machine can reproduce.
