Font API


An API to retrieve the similarity of computer fonts.
The algorithm calculates the relative similarity based on a semantic analysis of the appearance of the given fonts.

The similarity is measured based on 5 features:

  • weight (blackness)
  • entropy (complexity)
  • blackletter
  • curvature (roundness)
  • slant (diagonalness)
  • The API allows for cross comparisons between any of these features.

    You can upload and compare your own set of fonts or query for public ones. If you provide a weblink you can share it with other users.

    Read the Font API-Reference to get an overview on how to use the API.
