Inter can be classified as a geometric neo-grotesque, similar in style to Roboto, Apple San Francisco, Akkurat, Asap, Lucida Grande and more. Some trade-offs were made in order to make this typeface work really well at small sizes:
- Early versions of Inter was not suitable for very large sizes because of some small-scale glyph optimizations (like "pits" and "traps") that help rasterization at small sizes but stand out and interfere at large sizes. However today Inter works well at large sizes and a Display subfamily is in the works for really large "display" sizes.
- Rasterized at sizes below 12px, some stems—like the horizontal center of "E", "F", or vertical center of "m"—are drawn with two semi-opaque pixels instead of one solid. This is because we "prioritize" (optimize for) higher-density rasterizations. If we move these stems to an off-center position—so that they can be drawn sharply at e.g. 11px—text will be less legible at higher resolutions.
