Proportio is a tool for creating proportional design scales based on a chosen ratio, producing harmonious number sequences that can be applied to typography, spacing, and layout. The mathematical foundation ensures design decisions share a proportional relationship, creating a sense of visual coherence across a system. It is particularly useful for designers building systematic design tokens or seeking a principled basis for their typographic scale choices.
