# Free alternatives to Charter

Charter is a commercial transitional serif from Bitstream (Matthew Carter) (https://practicaltypography.com/charter.html). Bitstream Charter is free under a permissive license; commercial cuts (Charter ITC, XCharter) vary — check before web use. The name is used only to identify the typeface; BrandSweets does not host or embed it.

## Score

`score = 0.35·classification + 0.25·metrics + 0.20·traits + 0.10·useCase + 0.05·language + 0.05·variable`; every axis in [0, 1]. A family gate runs first: specialist families (blackletter, script, glyphic, stencil, monospace, pixel) only list same-family fonts; elsewhere a cross-family mismatch is capped at 0.2. Curated picks are listed first, then pure formula; ties break on popularity, then slug.
