TTF — Vertical Writing Metrics (vhea and vmtx)
A horizontal Latin face that also carries vhea and vmtx, so vertical-layout code has something small and predictable to run against: every glyph advances 1000 units downward with a 250-unit top side bearing. For testing writing-mode support and metric-table selection without needing a CJK font. Original typeface, free to use.

Testing contract
Expected to pass- Scenario
- Set writing-mode to vertical-rl and measure the advance of a run of capitals.
- Expected result
- Each glyph advances 1000 units vertically from vmtx rather than falling back to the horizontal advance, and vhea reports a 500/-500 vertical ascent and descent.
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 — Vertical Writing Metrics (vhea and vmtx)” is a deterministic Novus Examples fixture for Conversion testing, Metadata testing, Internationalization. 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 — Composite Glyphs (accents built from components)Four precomposed accented letters built the way real fonts build them — as composite glyphs referencing a base letter and a combining mark with a translation. For testing component resolution, nested-glyph handling, and subsetters that must keep a component's base glyph alive. Original typeface, free to use.
- ttcTTC — Collection of Two Variable FontsA collection whose members are themselves variable fonts, each with its own axis, fvar, gvar and STAT. The case that breaks loaders which handle collections or variations but never both at once. Original typeface, free to use.
- ttcTTC — Three-Face Collection with Shared TablesA TrueType Collection holding three faces of one family with identical tables stored once and referenced by offset from each face's table directory. For testing face-index selection, collection-aware loaders, and extractors that must not assume each face owns its tables. Original typeface, free to use.
- 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 — Colour Font, Apple sbix PNG StrikeAn sbix colour font — Apple's embedded-bitmap format, one 128 ppem PNG strike per icon glyph, with vector glyf outlines kept underneath for renderers that ignore sbix. For testing bitmap-strike extraction and the strike-versus-outline decision. Original typeface, free to use.
