Linux Libertine is a typeface released in 2003 by the Libertine Open Fonts Project, which aims to create free and open alternatives to proprietary typefaces such as Times New Roman. It was developed with the free font editor FontForge and is licensed under the GNU General Public License and the SIL Open Font License.[1]
In 2009, the project released Linux Biolinum: it is a sans serif font designed to pair well with Libertine.[2] It resembles Optima.
In 2012, a monospaced serif font face was released, Linux Libertine Mono.[3]
Characteristics
[edit]Linux Libertine is a proportional serif typeface inspired by 19th century book type and is intended as a replacement for the Times font family.[1]
The typeface has five styles: regular, bold, italic, bold italic, and small capitals, all of which are available in TrueType and OpenType format, as well as in source code. The OpenType version allows automatic positioning and substitution, including true fractions, ligatures and kerning. A display type variant, while similar in letter form, is lighter in weight and bears a closer resemblance to old-style types such as Palatino.
There is also a complementary humanist sans-serif face, Linux Biolinum, similar to Optima or Candara. It is available in bold and italic styles.
Unicode coverage
[edit]Linux Libertine contains more than 2,000 glyphs and encompasses character sets such as the Greek Alphabet, Cyrillic script, and Hebrew alphabet. Additionally, it offers several ligatures (such as ff, fi, and ct, and the capital ß). It also includes special characters such as International Phonetic Alphabet, arrows, floral symbols, Roman numbers, text figures, and small caps. The Tux mascot is included at the Unicode Private Use Area code point U+E000.
Usage
[edit]
In 2010, Linux Libertine was adopted as an open-source substitute for the Hoefler Text typeface in the redesign of the Wikipedia logo, making it possible to localize the Wikipedia identity into more than 250 languages and character sets.[4] The "W" character, which had previously been used in various other places in Wikipedia (such as the favicon) and was a "distinctive part of the Wikipedia brand", had "crossed" V glyphs in the original logo, while Linux Libertine has a joined W letter shape. As a solution, the "crossed" W was added to Linux Libertine as an OpenType variant.[5][6]
Both the Linux Libertine and Linux Biolinum typefaces are used by the open-source design publication Libre Graphics Magazine and the Association for Computing Machinery journals and conference proceedings.[7][8]
Derivative works
[edit]László Németh created a variant of fonts with additional Graphite font tables: Linux Libertine G and Linux Biolinum G.[9] Both these fonts are bundled with LibreOffice as of the suite's 3.3 release,[10] with some features added in the 3.5 release.[11]
Khaled Hosny forked the Linux Libertine font family in 2012[12] that stemmed from a lack of a matching mathematical companion font for Linux Libertine. He officially released the initial version of his fork in 2016.[13] Due to licensing restrictions of Linux Libertine regarding the need to change the name of derivative works, he renamed his version to Libertinus (including Libertinus Serif and Libertinus Sans).[14] Hosny also used this opportunity to unify the various font names. Thus, Linux Libertine became Libertinus Serif, Linux Biolinum became Libertinus Sans, and Linux Libertine Mono became Libertinus Mono. His new mathematical font is called Libertinus Math. While working on the mathematical companion, Hosny fixed many technical issues of the already existing fonts. This led him to a complete fork of Linux Libertine, not just adding a complementing typeface to it.[15] Since Linux Libertine's releases came to a halt in 2012,[16] the actively developed Libertinus fonts are de facto a continuation of the now stalled Linux Libertine project. Khaled passed the role of maintainer on to Caleb Maclennan in 2020.[17]
Stefan Peev forked the Libertinus Serif font to create the Common Serif font in 2022.[18]

Linux Libertine
View on Grokipediafrom Grokipedia
Linux Libertine is an open-source serif typeface family designed for use in documents and print media, serving as a free alternative to proprietary fonts such as Times New Roman.[1][2]
Initiated by Austrian type designer Philipp H. Poll in September 2003 under the Libertine Open Fonts Project, it was motivated by the limited quality of default fonts available in early GNU/Linux distributions like SUSE 9.x.[1][3]
The font draws inspiration from 19th-century book types, emphasizing elegant readability with features like bowed serifs, varied letter forms, and advanced typographic elements including ligatures, kerning pairs, small caps, old-style figures, and fractions.[4][1]
It includes over 2,600 glyphs supporting the Latin, Greek, and Cyrillic scripts, along with extensions for IPA phonetic notation and other characters, enabling multilingual use in Western European languages and beyond.[5][6]
A companion sans-serif font, Linux Biolinum, complements the family for headings and user interfaces.[3][7]
Released under the SIL Open Font License (OFL) version 1.1, with some components under the GNU General Public License, Linux Libertine is freely available for modification and redistribution. Official development halted after version 5.3.0 in 2012, but an active fork known as Libertinus continues to provide updates.[8][9]
The project achieved notable adoption, including bundling with LibreOffice since version 3.3 in 2011 and packaging for distributions like Debian, Fedora, and Ubuntu.[4][7]
History and Development
Origins and Founding
The Linux Libertine font project was founded in September 2003 by Philipp H. Poll, a German type designer, in response to his dissatisfaction with the default fonts available in GNU/Linux distributions, which he felt lacked high-quality, open-source alternatives to proprietary serifs such as Times New Roman.[1] Poll initiated the project to address the broader issue of intellectual property restrictions on essential typographic tools for communication and document creation.[10] This led to the launch of the Libertine Open Fonts Project as a community-driven initiative aimed at developing free and open-source typefaces under licenses like the GNU General Public License.[11] The project's foundational motivation, as articulated by Poll, was to provide accessible alternatives to copyrighted fonts: "Therefore we want to give you a free alternative: This is why we founded the Libertine Open Fonts Project."[10] The initial goals centered on creating a versatile serif font family suitable for practical document production, with a strong emphasis on classical book typography to evoke the elegance of 19th-century printing traditions.[4] Early development efforts relied on free software tools, notably FontForge, an open-source font editor, to design and refine the typeface starting from its inception in September 2003.[12]Key Milestones and Versions
The Linux Libertine font project gained public attention in 2006, when it was introduced with over 1,750 glyphs covering Latin, Greek, and Cyrillic scripts, positioning it as a free alternative to proprietary serif typefaces like Times New Roman.[1] A significant licensing update occurred with version 2.1.9 in late 2007, which added the SIL Open Font License (OFL) alongside the existing GNU General Public License (GPL), enhancing compatibility for broader distribution and modification while maintaining open-source principles.[10][13] Version 2.6, released in 2007, incorporated additions such as improved German umlaut variants with adjusted dieresis spacing for better typographic balance.[14][10] In version 2.7, also from 2007, developers introduced TrueType hinting to the TTF files for superior rasterization on Windows systems, alongside a GPL font exception clause to facilitate embedding in documents without requiring derivative works to be open-sourced.[10][13] Notable contributions include work by designer Andreas Stötzner, who influenced the development of the Versal-Eszett glyph (U+1E9E), officially encoded in Unicode in April 2008 following DIN standardization efforts.[10] Subsequent iterations expanded the glyph set to over 2,000 characters. As of 2025, the project remains actively maintained on SourceForge, with ongoing discussions seeking expertise in hinting to refine screen rendering quality.[3][10]Design and Characteristics
Aesthetic Influences and Style
Linux Libertine is a proportional serif typeface primarily inspired by 19th-century book types, designed to provide a free and open-source alternative to proprietary fonts such as Times New Roman.[6][4] Its aesthetic draws from classical typography traditions, emphasizing an organic approach that contrasts with the perceived "monoculture" of standardized digital fonts, aiming to introduce visual diversity and interest without direct imitation.[1] The typeface exhibits classical proportions optimized for high legibility in body text, featuring elegant and varied serifs that are often described as thinner and flatter compared to those in Times New Roman, contributing to a lighter overall color.[1] Subtle stroke contrasts enhance its readability, particularly in print media, while curved elements like the lowercase "e" and "c" adopt shorter, more refined forms to maintain an organic flow suitable for professional typesetting.[1] This design philosophy prioritizes versatility across print and digital applications, though it performs best in higher-resolution print environments where its nuanced details shine.[6][1] In comparison to standard Linux system fonts, Linux Libertine offers a more refined and polished appearance, avoiding the utilitarian starkness of defaults while steering clear of exact replication of commercial typefaces.[6] It is available in multiple weights, including regular and bold, to support varied typographic needs.[4]Glyph Set and Typographic Features
Linux Libertine features a comprehensive glyph set exceeding 2,000 characters, encompassing extended Latin alphabets, Greek and Cyrillic scripts, Hebrew, and additional symbols tailored for diverse typographic needs.[10] This inventory includes standard Latin extensions for Western European languages, along with arrows and decorative ornaments that enhance visual appeal in technical and artistic contexts.[10] The font's design prioritizes readability and versatility, supporting a wide array of scripts while maintaining aesthetic consistency across its serif family, including italic and bold variants. Key typographic features distinguish Linux Libertine, enabling precise control over text rendering for professional applications. Small capitals are fully supported in all styles, allowing for elegant emphasis in titles and abbreviations without disrupting line height.[15] Old-style figures provide a historical flair with proportional numerals that include ascenders and descenders, ideal for body text to blend seamlessly with lowercase letters.[10] Complementing this, tabular figures offer monospaced alternatives for accurate alignment in tables and data presentations.[10] Ligatures further refine the font's legibility by substituting common letter combinations with custom glyphs, such as fi and fl, which prevent awkward overlaps and improve flow in running text.[15] Standard ligatures (liga feature) handle pairs like ff, fi, fl, and ffl, while discretionary (dlig) and historic (hlig) options extend to combinations like tz, ct, and st for stylistic variation.[15] For specialized uses, the glyph set incorporates mathematical operators, including Greek letters and equilibrium arrows, alongside a complete International Phonetic Alphabet (IPA) for linguistic notation.[10] These elements ensure Linux Libertine serves effectively in scientific, academic, and multilingual documents.Technical Specifications
Unicode Coverage and Scripts
Linux Libertine provides comprehensive coverage for several key Unicode blocks, enabling support for a wide array of Western European and related languages. Its primary coverage includes the Basic Latin block (U+0000–U+007F), which forms the foundation for English and other simple Latin-script texts, as well as extensive Latin Extended blocks such as Latin-1 Supplement (U+0080–U+00FF), Latin Extended-A (U+0100–U+017F), and Latin Extended Additional (U+0180–U+024F), supporting diacritics and characters for languages like French, German, Spanish, Portuguese, Vietnamese, and various African and Indigenous languages.[16] The font also offers strong support for the Greek and Coptic block (U+0370–U+03FF), covering nearly all characters including polytonic variants for ancient and modern Greek. Cyrillic script (U+0400–U+04FF) is similarly well-represented, with extensive glyphs available, including extensions for Slavic languages such as Russian, Bulgarian, Serbian, and Ukrainian. These features are complemented by robust glyph support for diacritics across combining marks (U+0300–U+036F and U+1DC0–U+1DFF), punctuation variants in the General Punctuation block (U+2000–U+206F), and currency symbols (U+20A0–U+20CF), facilitating accurate typesetting for Western European multilingual documents.[17][18] Additional scripts include basic Hebrew (U+0590–U+05FF), with a large part of essential characters suitable for simple textual use, the International Phonetic Alphabet via the Phonetic Extensions block (U+1D00–U+1D7F), and subsets of mathematical symbols from blocks like Mathematical Operators (U+2200–U+22FF) and Superscripts and Subscripts (U+2070–U+209F). The font has expanded from an initial approximately 1,750 glyphs to over 2,000 in version 5.3.0 (released July 2012), with no official updates since.[17][16][18][19] Limitations are evident in partial support for complex right-to-left scripts like Arabic (U+0600–U+06FF), where contextual shaping is not fully implemented, and a complete absence of coverage for CJK (Chinese, Japanese, Korean) ideographs in blocks such as CJK Unified Ideographs (U+4E00–U+9FFF). This focus prioritizes European and adjacent scripts, making Linux Libertine particularly suitable for academic and publishing contexts involving those languages.[16]OpenType Support and Implementation
Linux Libertine incorporates a range of OpenType features to enhance typographic flexibility and readability across diverse applications. These include ligature substitution for standard combinations such as "ff," "fi," and "fl," as well as historic ligatures like "st" and "ct," and discretionary ones such as "tz," which are activated via theliga, hlig, and dlig tables to improve text flow and aesthetic harmony.[6][10] Contextual alternates are supported through the ccmp and fina features, enabling adjustments like short-neck "f" forms and Greek word-ending sigma, while stylistic sets (salt and ssXX) provide variant glyphs for elements such as German umlauts with closer dots, flexible "K" and "R" shapes, and Swiss German "ss/SS" forms.[6][10]
Kerning is implemented via the GPOS table using class-based kerning pairs, which group similar glyphs (e.g., "V" and "W") for efficient spacing adjustments and reduced file size, ensuring precise letterfit in complex layouts.[10] The font also supports fractions through the frac feature, rendering true fractions like ¼ for denominators 2 through 8, with composable forms for others such as 1/10, and includes superscript (sups) and subscript (sinf) positioning optimized for numbers, basic Latin characters, and symbols like plus and minus.[6][10] Additional features encompass small capitals (smcp and c2sc) that are manually designed across all styles, multiple numeral variants including proportional (pnum), tabular (tnum), old-style (onum), and zero-marked sets (zero), further extending its utility for professional typesetting.[6]
The font's OpenType tables were developed using FontForge, an open-source font editor, which facilitated the creation and maintenance of its source files (SRC format) for both OTF and TTF outputs.[6][10] Starting with version 2.7, TrueType hinting was introduced to improve on-screen rendering, particularly on Windows systems, by providing instructions for better pixel alignment at small sizes without altering the outlines.[10]
Linux Libertine demonstrates strong compatibility with advanced typesetting engines like XeLaTeX and XeTeX, which fully leverage its OpenType capabilities for high-quality output in document preparation.[10] Its licensing under the Open Font License (OFL) since version 2.1.9 and the GPL with Font Exception since version 2.7 permits embedding and modification in various software environments, promoting widespread adoption while protecting the font's integrity.[10]
Usage and Adoption
Integration in Software and Systems
Linux Libertine is bundled in several major Linux distributions, making it readily available for users without manual installation. In Debian, it is provided through thefonts-linuxlibertine package, which includes both the serif Linux Libertine and sans-serif Linux Biolinum variants.[7] Similarly, Fedora includes it via the linux-libertine-fonts package, offering TrueType fonts as a free alternative to proprietary typefaces for document use.[20] Ubuntu repositories also feature the fonts-linuxlibertine package, supporting advanced typographic features like ligatures and OpenType fractions.
The font integrates seamlessly with popular office suites and typesetting systems. In LibreOffice, Linux Libertine has been available as a bundled option since version 3.3 in 2011, with additional features added in version 3.5.[21] For LaTeX users, the libertine package on CTAN provides comprehensive support, loading the fonts in both Type 1 and OpenType formats for pdflatex, xelatex, and lualatex workflows.[22]
Installation methods cater to both manual and automated preferences. Users can download the latest releases directly from the official SourceForge project page for manual setup on any system, extracting the TrueType files to the appropriate font directories.[3] For Linux environments, system-wide installation is facilitated by package managers such as apt on Debian and Ubuntu derivatives or dnf on Fedora, ensuring fonts are registered and accessible across applications.[7][20]
Cross-platform compatibility is enabled by its SIL Open Font License (OFL), permitting free installation and use on Windows and macOS alongside Linux.[23] The fonts include TrueType hinting instructions, which improve on-screen rendering clarity at small sizes across these operating systems, particularly in applications like Adobe InDesign.[10] This broad support extends to multilingual documents handling Western European scripts.[6]
