<h1>The Interface font family</h1>
<p>
Interface is a font for highly legible text on computer screens.<br>
<a href="https://github.com/rsms/interface/releases/latest/">Download the latest release</a>
or try it out in the <a href="lab/">playground</a>
</p>
</div></div>
<div class="row white" style="padding-bottom:0"><div>
<h2><a id="sample" href="#sample">Sample</a></h2>
<p style="margin-bottom:0">
<img src="res/sample.png" style="width:100%;display:block">
</p>
</div></div>
<div class="row dark"><div>
<h2><a id="free" href="#free">How much does it cost?</a></h2>
<p>
Interface is a <a href="https://github.com/rsms/interface">free and open source</a> font family. You are free to use this font in almost any way imaginable.
Refer to the <a href="https://choosealicense.com/licenses/ofl-1.1/">SIL Open Font License 1.1</a> for exact details on what the conditions and restrictions are.
</p>
<p> </p>
<h2><a id="usage" href="#usage">How do I use it?</a></h2>
<p>
Using the font is as easy as
<a href="https://github.com/rsms/interface/releases/latest/">download & installing</a> locally on your computer.
</p>
<p>
You're free to bundle copies of Interface with your software, even if it's
commercial and you charge money for your software. Interface can also be used
on the web by either hosting the font files yourself or by including this CSS:
</p>
<code>@import url('https://rsms.me/interface/interface.css');</code>
<p>Use the following CSS rules to specify the Interface family:</p>
<code>font-family: Interface, sans-serif;</code>
</div></div>
<div class="row"><div>
<h2><a id="story" href="#story">The story behind Interface</a></h2>
<p>
Interface started out in late 2016 as an experiment to build a perfectly
pixel–fitting font at a specific small size (11px.) The idea was that
by crafting a font in a particular way, with a particular coordinate system
(Units Per EM), and for a particular target rasterization size (11), it would
be possible to get the best of both sharpness and readability.
</p>
<p>
However after a few months of using an early version of Interface, it dawned
on everyone exposed to the test that this approach had some serious real–world
problems. Most notably that it was really hard to read longer text. Because of
the pixel–aligning nature of that approach, the font took an almost mono–spaced
appearance, making it really easy to read numbers, punctuation and very short
words, but eye–straining to read anything longer.
</p>
<p>
The project was rebooted with a different approach, sticking with the
specific UPM, but crafting glyphs and kerning in a way that made for
more variation in the rythm and smoother vertical and horizontal stems.
As Interface was being developed, it was tested on an internal version of
<a href="https://www.figma.com/">Figma</a>—where the author of Interface works as a designer—and slowly improved upon based on experience and feedback.
</p>
<p> </p>
<h2><a id="status" href="#status">Current status & usability</a></h2>
<p>
Interface works great for English–language text, and pretty well for other
Latin and Cyrillic languages. There's still a lot of work to be done, and
<a href="https://github.com/rsms/interface#contributing">contributions are warmly welcomed</a>. The playground contains <a href="lab/?sample=Body%20text%201&size=16">a lot of samples</a>, including some common <a href="lab/?sample=Kerning%20body%20multi-lang&size=16">non English–language words in the playground.</a>
</p>
<p>
<a href="lab/?sample=Repertoire&size=42" id="repertoire-image"></a>
</p>
<p>
Please refer to the <a href="lab/?sample=Repertoire&size=42">glyph repertoire</a>
for an overview of currently–available glyphs and their quality.
