Inspector Font Finder

The tool analyzes a font resource supplied by URL, font file, or CSS @font-face declaration to extract typography data. It identifies font-family name, available styles, weights, and axes for variable fonts. It computes core metrics such as units_per_em, ascender, descent, and estimates x-height and cap height when exact values are not embedded. It also reports the glyph count and script coverage, enabling quick assessment of language support and rendering behavior. Outputs are structured for integration into design systems and style guides, with results suitable for developers implementing typography in web or print contexts. It does not render fonts, only analyzes data.

Conceptually, the tool parses the font data, normalizes metric values to common units, and derives properties useful for design decisions. It inspects kerning tables to summarize available kerning pairs, flags fonts with missing critical glyphs, and checks for licensing metadata when present. It supports multiple sources in a single analysis, enabling side-by-side comparisons between families or across weight ranges. It is beneficial for brand teams ensuring consistent typography, for web developers optimizing font loading by understanding file formats and subset needs, and for QA teams validating typography against specification.

Unique value comes from combining metric extraction, script coverage analysis, kerning awareness, and licensing context in a single pass, with outputs designed for automated pipelines and human review. Core features include: font-source variability, metric extraction, script coverage mapping, kerning data summary, format and license hints, and export options. Typical use cases include auditing brand fonts, selecting fallback families, and preparing data for style guides or design tokens. The tool emphasizes accuracy in metric estimation and clear reporting to reduce guesswork in typography decisions.
