About

No frills. No gimmicks. Hack is hand groomed and optically balanced to be a workhorse face for code.

It has deep roots in the libre, open source typeface community and expands upon the contributions of the Bitstream Vera & DejaVu projects. The face has been re-designed with a larger glyph set, modifications of the original glyph shapes (including distinct point styles and semi-bold punctuation weight in the regular set to make analphabetic characters less transparent), and meticulous attention to metrics (including numerous spacing adjustments to improve the rhythm of the face and the legibility of code at small text sizes). The large x-height + wide aperture + low contrast design combined with PostScript hinting/hint replacement programs and a TrueType instruction set make it highly legible at commonly used source code text sizes with a sweet spot that runs in the 8px - 12px range on modern desktop and laptop monitors. Combine it with an HD monitor and you can comfortably work at 6 or 7px sizes. The full set of changes are available in the changelog.

The font binaries are released under a license that permits unlimited print, desktop, and web use for commercial and non-commercial applications. It may be embedded and distributed in documents and applications. The source is released in the widely supported UFO format and may be modified to derive new typeface branches. The full text of the license is available in LICENSE.md

Desktop Usage

Recommended Binaries for OS X Users

The .otf or .ttf files may be used on OS X platforms.

Recommended Binaries for Linux and Windows Users

The .ttf files are recommended for screen use on Linux and Windows platforms.

Webfont Usage

Hack webfonts are released in svg, eot, ttf, woff, and woff2 formats. They include a complete Hack character set build and a smaller basic Latin + Latin-1 supplement Unicode character block build. The latter build set is smaller in size and is intended to improve page loading times when you do not need the entire Hack character set.

You can view the rendering of the webfonts at a range of sizes on the Hack type specimen.

Hack by CDN

Thanks to the generous gang at jsDelivr, you can use a CDN to include Hack on your site with a single stylesheet link in the head of your HTML files. There is no need to download font files from the repository or serve them from your web server.

Average latency, average uptime, and total downtime data for jsDelivr vs. other popular CDN are available for http and https protocols. Please understand that this is a free CDN resource and, while it does have industry backing, it could go away at anytime. If this is a critical issue for your use scenario, please purchase your own CDN plan and host the webfonts yourself.

Include one of the following lines in the <head> section of your site's HTML:

Basic Latin + Latin-1 Supplement Character Set
<link rel="stylesheet" href="//cdn.jsdelivr.net/font-hack/2.010/css/hack.min.css">
Full Character Set
<link rel="stylesheet" href="//cdn.jsdelivr.net/font-hack/2.010/css/hack-extended.min.css">

Then style your text by including Hack in the appropriate font-family property of your CSS. For example:

code {
	font-family: Hack, monospace;
}

The bold, oblique, and bold oblique text styles are formatted with HTML using <b>text block</b>, <i>text block</i>, and <b><i>text block</i></b> HTML tags, respectively.

Push the css and fonts directories to your web server, then import one of the included CSS files in the head section of the HTML where you would like to use it.

Replace path/to/ with the actual path to your css directory.

Basic Latin + Latin-1 Supplement Character Set
<link rel="stylesheet" href="path/to/css/hack.min.css">
Full Character Set
<link rel="stylesheet" href="path/to/css/hack-extended.min.css">

You can alter the path to the Hack files (e.g. place the files in a hack resource subdirectory); however, please make sure that you preserve the relative file paths included in the release archive (or be prepared to modify the paths to the font files).

Then style your text by including Hack in the appropriate font-family property of your CSS. For example:

code {
	font-family: Hack, monospace;
}

The bold, oblique, and bold oblique text styles are formatted with HTML using <b>text block</b>, <i>text block</i>, and <b><i>text block</i></b> HTML tags, respectively.

Webfont Caching and gzip Compression with Cloudflare

The following information applies to both paid and free accounts

If you use Cloudflare, woff files are cached by default. To cache the remaining webfont files, add a new page rule for the path to your fonts directory:

yoursite.com/path/to/fonts/

and set the rule to Cache Everything.

Cloudflare automates gzip compression of ttf, eot, woff, and svg font files. The service does not gzip compress woff2 files.
