Font Info
Read the metadata stored inside a font file without installing it. Upload a TTF, OTF, WOFF or WOFF2 font and see its family and style names, version, designer, copyright and license, outline format, glyph and character counts, vertical metrics, weight and width classes, variation axes, OpenType features, supported scripts and embedding permissions. Useful for designers, developers and anyone checking a font license.
Frequently asked questions
Which details does Font Info show?
It reads the name table for family, style, full name, PostScript name, version, designer, manufacturer, copyright and license, and reports the container and outline format, file size, glyph and character counts, units per em, ascender, descender, line gap, cap height, x-height and italic angle. It also lists the weight and width classes, whether the font is monospaced or variable, its axes and named instances, OpenType features, scripts, embedding permissions and table tags.
Which font formats are supported?
TTF and OTF fonts with TrueType, CFF or CFF2 outlines, and WOFF and WOFF2 web fonts, up to 10 MiB per file and 30 MiB once decompressed. WOFF and WOFF2 files are unpacked first, so the values describe the font inside the container. Font collections (TTC) are not supported.
How are the supported scripts worked out?
Every code point in the font's character map is assigned its Unicode Script property and counted, so Latin (95) means 95 Latin characters are mapped. Common covers digits, punctuation and symbols shared by many scripts, and Inherited covers combining marks. Script names are shown in the language of the page.
What do units per em and the vertical metrics mean?
Font outlines are drawn on a grid, and units per em is the size of one em on that grid, often 1000 for CFF fonts and 2048 for TrueType fonts. Ascender, descender, line gap, cap height and x-height are given in those units. Divide a value by units per em to get its size relative to the font size.
What does the embedding line mean?
It decodes the fsType field of the OS/2 table, which states how the font may be embedded in documents. Installable allows any use, restricted forbids embedding, preview and print allows read-only embedding, and editable allows editing the document. Two extra flags can forbid subsetting or allow only bitmap embedding.
What are the weight class and width class?
The weight class runs from 100 to 900, where 400 is regular and 700 is bold. The width class runs from 1 to 9, where 5 is normal, lower values are condensed and higher values are expanded. Operating systems use both values to group styles into families.
How are variable fonts described?
Each axis is listed with its name, four-letter tag, minimum, maximum and default value, for example Weight (wght) from 100 to 900. Named instances are predefined positions such as Bold or Light, and their count is shown. Variable is yes whenever the font has variation axes.
What does the features list contain?
It lists the OpenType layout feature tags the font defines in its GSUB and GPOS tables, or the equivalent AAT features, such as kern for kerning, liga for ligatures, tnum for tabular figures or ss01 for a stylistic set. A tag in the list means the font contains rules for it. None means the font has no layout features.
Why are some fields missing from the result?
Name entries such as designer, license or license URL are optional, and lines whose value is empty are left out. Copyright and license texts longer than 400 characters are shortened. The tables line always shows every table tag that is present.
Is my font uploaded and stored?
The font is sent to our server, read in memory for this request and discarded as soon as the result is returned. Nothing about the font is saved. Only the details shown on the page are produced.
