Grid-Based IconsGenerate a matching set with AI
Grid-based icons obey a keyline system: every shape snaps to a fixed grid, circles and squares share optical bounding sizes, and stroke positions land on whole pixels. This is the discipline behind platform icon sets — the reason a hundred different glyphs feel like one family.

When to use grid-based icons
Choose grid-based styles when the destination is a design system or a large product where dozens of contributors will add icons over years. The keyline discipline makes icons interchangeable: consistent optical weight, consistent margins, no glyph looking bigger than its neighbors. It is the most "invisible" style on this list — and for system UI, invisible is the goal.

- Design systems and component libraries
- Enterprise product suites
- Icon fonts
- Platform-consistent apps
- Long-lived codebases

Frequently asked questions
What is a keyline grid?+
A set of template shapes — square, circle, tall and wide rectangles — sized so each reads optically equal inside the icon frame. Drawing every glyph against the same keylines is how platform sets keep a hundred icons visually interchangeable. Icora generates against a consistent grid per batch.
Why do my icons look different sizes even at the same dimensions?+
Optical weight: a solid square at 20px looks bigger than a thin circle at 20px. Keyline systems compensate by letting round and thin shapes extend slightly beyond square bounds. A grid-based set bakes these compensations in, which is exactly what makes it feel calm.
