TTF — Vertical Metrics: hhea, typo and win All Agree
The control case: all three vertical-metric families carry the same numbers, so every platform computes the same 1.0 em default line height. Measure this first, then measure its disagreeing twin — the difference is entirely the metrics. Original typeface, free to use.

Testing contract
Reference control- Scenario
- Set the font at 100 px with default line height on macOS, Windows and Linux and measure the line box.
- Expected result
- Every platform reports a 100 px line box, because hhea, OS/2 typo and OS/2 win all sum to 1000 units at 1000 upem.
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 Metrics: hhea, typo and win All Agree” is a deterministic Novus Examples fixture for Conversion testing, Metadata testing, Editor 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.
Code examples
@font-face {
font-family: "Sample";
src: url("NovusMetricsAgree.ttf");
}

- ttfTTF — Kerning in the Legacy kern Table (same 18 pairs)The same eighteen kerning pairs, this time in a format-0 legacy kern table with no GPOS at all. Modern shapers ignore kern when GPOS exists and some ignore it entirely, so this twin is how you tell which code path produced a given measurement. Original typeface, free to use.
- bdfBDF — 5x7 Bitmap Font (digits)A hand-written 5×7 BDF bitmap font covering the digits, a colon, and space — the classic X11 bitmap-font format, in plain text. A fixture for testing BDF parsers, bitmap-font converters, and retro/embedded rendering.
- 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 — Access All Alternates (aalt)An aalt feature that aggregates every alternate reachable through the stylistic sets and the small-cap set, which is what a glyph-palette UI reads to offer 'other forms of this character'. For testing alternate-picker panels rather than automatic shaping. 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.
