Precomposed fraction glyphs - ½, ⅓, ⅗ - are single characters that typeset like real fractions: numerator raised, slash slanted, denominator lowered, all in one glyph. This table lists every one Unicode encodes, with code points, HTML entities and decimal values, so you can pick the glyph when it exists and know when it does not.
The collection is deliberately small: the original Latin-1 trio (¼, ½, ¾) came from 1980s typographic sets, and the Number Forms block U+2150–U+215F later added the eighths, thirds, fifths, sixths, sevenths, ninths and tenths that recipes, music theory and old measurement systems actually use. Unicode has resisted adding more - the fraction slash mechanism covers the rest.
How to use
- Type a name, value or code to filter - 'half', '2153', 'eighth' and '0.333' all work.
- Click any fraction to copy the glyph itself, ready for recipes, documents and sheet music.
- Use the HTML column in markup: ½, ¾ and their cousins have named entities; the rest use the numeric form shown.
Frequently asked questions
Why is it called a vulgar fraction?
Vulgar here is the old sense of the ordinary or the vernacular - a fraction written the common way (numerator over denominator) rather than as a decimal. The term predates any rude connotation by centuries; Unicode kept the typographic tradition in the official name VULGAR FRACTION ONE HALF. Mathematicians may say common fraction; the glyphs themselves are indifferent to the label.
How do I type a fraction that has no glyph, like 2/7?
No precomposed character exists beyond the 19 in this table. The Unicode-endorsed trick is the fraction slash U+2044: type 2, then U+2044, then 7, and typography-aware renderers (and many word processors) build the fraction on the fly. In plain HTML, the sup/sub pattern with a slash span is the honest fallback - a real slash character between full-size digits is what most browsers will show.
Why do 1/3 and 2/3 have named HTML entities but 1/5 does not?
HTML's named entity set froze around the symbols that page authors demonstrably used most: ½, ¼, ¾ from Latin-1 and a handful from Number Forms like ⅓ and ⅔. The rarer sevenths and ninths predate web usage patterns and only get numeric references (⅐), which work identically in every browser - the name is a convenience, not a capability.
Do these glyphs work in code identifiers and search?
½ in a URL is a different character from 1/2 and will break route matching - keep code and identifiers ASCII. In content, the glyphs are fine, but search engines normalize them: a page about 1/2-cup measures should usually write 1/2 in text and can use ½ as decoration, since recipes that pair the word with the glyph match more queries than either alone.
