TTF — Variable Font, opsz Axis (Optical Size)
A single-axis variable font on the registered opsz axis, built from 3 interpolating masters so the deltas are real — stems thicken and tracking opens at small optical sizes and reverse at display sizes. Named instances and a STAT table are included. Original typeface, free to use.

Testing contract
Expected to pass- Scenario
- Read fvar, then render the same string at the opsz minimum, default and maximum.
- Expected result
- fvar reports exactly one opsz axis (opsz 8..14..72); the three renderings differ, and the named instances resolve through STAT.
What is a .ttf file?
TTF (TrueType Font) is a scalable outline font format developed by Apple and Microsoft that uses quadratic Bezier curves and includes hinting for sharp rendering at small sizes. It stores glyph outlines, metrics, and character mappings in a single file. It is one of the most widely supported desktop and web font formats.
How to use this file
Use an example TTF to test font parsers, glyph and metric extraction, text-rendering pipelines, and converters that produce web font formats like WOFF.
How to use this file for testing
“TTF — Variable Font, opsz Axis (Optical Size)” is a deterministic Novus Examples fixture for Conversion testing, Web assets, Metadata testing. The same content exported across many formats and linked as a group, so you can convert one and diff against the expected twin.
Documented properties for this file: seed 20260807. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.
Font fixtures carry a small documented glyph set across the common wrappers. Test font loaders, subsetting, and @font-face; the specimen preview renders the glyphs the face actually maps.

- ttfTTF — Colour Font with Four Named CPAL Palettes (light/dark)A colour font carrying four CPAL palettes with name-table labels and palette-type flags, two of them marked usable with a light or a dark background. For testing palette pickers, the CSS font-palette property, and renderers that only ever read palette zero. Original typeface, free to use.

- ttfTTF — Static Instance, Black (wght 900)A real static instance cut from the wght variable font at 900 — outlines interpolated once and baked, fvar and gvar stripped, usWeightClass set to match. For testing static-versus-variable fallback paths and family/style grouping. Original typeface, free to use.

- ttfTTF — Static Instance, Bold (wght 700)A real static instance cut from the wght variable font at 700 — outlines interpolated once and baked, fvar and gvar stripped, usWeightClass set to match. For testing static-versus-variable fallback paths and family/style grouping. Original typeface, free to use.

- ttfTTF — Static Instance, Condensed Bold (wght 700, wdth 75)A two-axis instance baked out of the weight-by-width variable font, with both usWeightClass and usWidthClass set to match. For testing that a family grouper reads width from OS/2 rather than guessing it from the style name. Original typeface, free to use.

- ttfTTF — Static Instance, Light (wght 300)A real static instance cut from the wght variable font at 300 — outlines interpolated once and baked, fvar and gvar stripped, usWeightClass set to match.
