If you're looking for a UI font that's non-specific to your design (ie. you're not designing a poster) then I recommend the following:

font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, Helvetica, Arial, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol";

Everything else is less user friendly. This loads instantly, looks perfect on the user's screen, and is guaranteed to look exactly as it's supposed to.

>Everything else is less user friendly.

Not really.

By using a font like Inter UI you create the same experience for everybody, regardless of the platform.

Segoe UI, Ubuntu, Cantarell (Windows, Ubuntu, Gnome/Fedora) are within a different typographic category than San Francisco or Roboto, they're not even similar enough to each other. By using the system font stack you're basically fragmenting the user experience and look and feel.

Inter is a substitute for well crafted neo grotesque fonts loved by designers, like San Francisco (which itself is a better fitting alternative to Helvetica), it's of a similar quality.

Agreed. Few designs benefit enough from a custom font to justify the downsides of not using the standard system font.

As an aside, we will soon be able to use system-ui in place of a manually constructed font stack: https://caniuse.com/#feat=font-family-system-ui

This one includes a few more devices:

font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", "Roboto", "Oxygen", "Ubuntu", "Cantarell", "Fira Sans", "Droid Sans", "Helvetica Neue", sans-serif

Might want to throw a “system-ui” in there too, from CSS 4. This works for me in Safari sand Chrome.

Can't one just use font:menu?
[+] tqkxzugoaupvwqr|7 years ago|reply
Isn’t sans-serif a catchall which means the emoji fonts will never be used?
[+] rf15|7 years ago|reply
I'm sorry but have you considered that there are people who don't actually own a Mac?

As I see it, this is very centric to a specific system and therefore does not offer the best user experience for everyone.

For anyone like me who might think that this is a pretty looking typeface but not particularly fully featured, scroll down the page to this bit: https://rsms.me/inter/#features

This is an amazingly well featured typeface where the author clearly has considered a number of use cases, particularly in terms of legibility at small sizes which is important for UI. This looks great! File size may be an issue for public web UIs, as someone mentioned, but there are so many more places this could be used to great effect. Will definitely consider for future projects!

[+] GordonS|7 years ago|reply
Ah, I was thinking there was no slashed zero, but scrolled further after reading your comment - it is indeed there as an option!
[+] TheAceOfHearts|7 years ago|reply
FYI: it's a bit easier to spot the variations if you highlight both the Disabled and Enabled examples in a line. The light-green blocks by themselves definitely make it harder for me to make out the details, but once highlighted the improvements are much more obvious.

What's the difference between 2:34, FE—X and 12:34, FE—X, 4.2 and 4.2, (SEMI)PERMANENT and (SEMI)PERMANENT? I can see no difference.
[+] Semaphor|7 years ago|reply
Wow, it even has a visible difference for capital ß (ẞ) which is usually barely perceptible.
[+] TheAceOfHearts|7 years ago|reply
I really like the typeface, so I hope this comment won't come off as too negative. In the FAQ the author mentions that you can fetch the typeface directly from his site. I'd advise against relying on third-parties without contractual obligations to you in production.

If you decide to take this risk anyway then you should take steps to reduce the risk of future security issues. The most important thing is to use use Subresource Integrity [0] on your <link> tags. However, since the author doesn't provide versioned URLs (the query strings are only being used to bust the cache, not to select which file is served), this would likely cause your site to break on each release. Usually CDNs give you a URL which includes the version as part of the path.

Another issue is that SRI only checks top level resources, there's no equivalent for external fonts and images which get included from the stylesheet [1]. It doesn't seem like the largest attack vector, but you never know what kinds of browser bugs might pop up.

Finally, Cache-Control has a max-age of 4 hours. If you don't expect these resource to change then you'd want the value to be way longer.

Looks good! I haven't seen many variable fonts around yet. The samples include mock notebooks and poster layouts, but I'd love to see examples of it being used in an actual interface. (Outside of the site, which uses it.)

Also—not mentioned too prominently on the site—but it's open source as well! Awesome work. https://github.com/rsms/inter

[+] kragen|7 years ago|reply
TeX can use other fonts, but the default set of fonts used in TeX are "variable fonts". The term Knuth used was "metafonts", which is why the font-rasterizing program he wrote for TeX is called METAFONT. So you've probably read a number of books and many papers typeset in "variable fonts", as well as most of the math formulas on Wikipedia and in Jupyter.

Despite all the talk about being optimized for screen rendering, it sure looks lot blurrier and less even on my system than for example the classic Verdana, or the more modern Segoe UI

Here is quick and dirty comparison shot:

On my Linux and Firefox, font looks unpleasantly blurred in small sizes on their page. Maybe our hinting settings are different than theirs but that should not be a problem in a quality font.

Kerning in digits looks off in their example: https://i.imgur.com/AURrPtn.png (this is an example where fixed-width is disabled), don't know how pervasive this odd kerning is, or if this is bad only in the browser. Another example of bad kerning: https://i.imgur.com/PIYJgIz.png One more example: https://i.imgur.com/bOM4MZB.png

[+] crazygringo|7 years ago|reply
That's clearly rendering without any hints.

The page mentions they have both hinted and unhinted files you can use... but they recommend only using them for Windows where users prefer that look. (You clearly do.) I'm guessing you're using the unhinted one?

[+] johnday|7 years ago|reply
That does look way blurrier. Interesting though, since it seems to work fine on my screen. Are you using a standard pt / px size?
[+] _fbpt|7 years ago|reply
The hinting renders poorly on your system. Aside from the fuzziness?, the T and top of z are thicker than bottom of z.
[+] needle0|7 years ago|reply
Since this font contains the feature, let me mention one of my pet peeves in the hopes of raising awarenes: whatever you do, do NOT blanket enable the Discretionary Ligatures (dlig) feature across all of your header/body text. Use it sparingly, pinpointed to where you know in advance there are specific glyphs in the text that need to look different. Enabling it all across your text with no regard on what text there will be will result in all kinds of unintended ligatures making the text appear bizarre, ugly and unprofessional, especially if there is any chance your text will be localized into non-latin languages. ​
[+] em-bee|7 years ago|reply
can you give an example of where unintended ligatures could appear?
[+] andrewthebold|7 years ago|reply
I think if anybody is interested in using this as a webfont, you should take a look at the file sizes of the typeface. They're about 100-200kb each, which adds up if you're using multiple font weights. It could be significant depending on the context of your app.

Apparently this is because the font has a lot of glyphs that may not exist in other optimized web fonts (relevant GitHub issue: https://github.com/rsms/inter/issues/53).

[+] cpmsmith|7 years ago|reply
As mentioned in that issue and the linked one, subsetting makes a huge difference, and can be done yourself. As not mentioned there, you can even split the subsets by Unicode range and let browsers handle which chunks to download. Browser support is even pretty good.[0]

This font (under default metrics settings) reminds me of Apple’s San Francisco. Is it similar, or are my eyes just deceiving me? (I’d check myself, but I’m on my phone at the moment.)
[+] cpmsmith|7 years ago|reply
It's a very similar style with very similar objectives, so it's not entirely coincidence. It's also very similar to Google's Roboto for the same reasons.
[+] fredsted|7 years ago|reply
To me it looks almost the exact same, but there's some small differences. These two fonts are exceedingly similar.
[+] zepto|7 years ago|reply
It is ‘similar’ in every way.
[+] TheRealPomax|7 years ago|reply
That capital U is kind of horrible though. No compensation at large size for what the human eye perceives as a line-curve discontinuity on the inside of the glyph?
[+] classichasclass|7 years ago|reply
I like this much better than the typical Linux UI fonts, too. It looks cleaner and more visually pleasing. Would certainly enjoy using a desktop with this.
[+] andai|7 years ago|reply
I just set my desktop UI to this font. everything is pretty now. It almost feels like I'm on macOS :)
[+] Theodores|7 years ago|reply
I had to choose a font recently, working with the client there were a few things such as 'no I don't want the eyeglasses g' and 'no I don't want descenders on numbers' and that was how we arrived at using 'Ubuntu' to fall back to the native font stack. This I was pleased with as Ubuntu is a system font on Ubuntu so working on a website where there is no need to download a 'Google Font' helps immensely when the cache is off.

However, I didn't like the 'M' and 'W' in Ubuntu, so I think I will be suggesting that we revise the font to this neat Inter UI font, loaded with 'defer' and the system fallbacks including Ubuntu.

This font is a very neat piece of work. It satisfies the 'g' and numbers requirements and is sans-serif. I can't wait to get working with it.

[+] romanr|7 years ago|reply
Is it English/Latin only? What about localized interfaces?

Looks like apart from standard Helvetica/Apple/Microsoft fonts there’s a very small choice of fonts you can use if you have multi lingual UI.

It’s like creating a Latin font is relatively easy, but very few of them go all the way to full Unicode support.

[+] alwillis|7 years ago|reply
By opening the font file using FontDrop (https://fontdrop.info), you can see that it supports 39 languages:

Afrikaans Albanian Azerbaijani Belarusian Bosnian Bulgarian Catalan Croatian Czech Danish Dutch English Estonian Finnish French German Hungarian Icelandic Italian Latvian Lithuanian Macedonian Maltese Norwegian Ossetic Polish Portugese Romanian Russian Serbian Slovak Slovenian Spanisch Swedish Turkish Ukrainian Uzbek Vietnamese Zulu

I love the way this font looks to an irrational extent. Will use in my work.

It has the 80s modern vibe with today's technology. It definitely tickles something deep down in my mind too.
[+] zaroth|7 years ago|reply
The site seems to constantly crash mobile Safari in my iPhone X?

I’m getting “A problem repeatedly occurred while trying to load...” after it crashes and tries to reload several times.

I think the first time I’ve ever seen that actually.

[+] Kuraj|7 years ago|reply
Looks pretty but I wish the website showed it as a webfont instead of just a picture, so I can see how it will really look on my system (the differences in hinting can be substantial)
[+] ncmncm|7 years ago|reply
Sigh. Yet another sans-serif font family.

Yes, they are easier to design, and easier to parameterize, which is nice for you, the designer. But they are not nice for me, the reader. Using a sans font says to me that your comfort is more important than mine, and that your time is worth more than mine and everyone else's, combined.

In Firefox, I have disabled web fonts, and use Libertine everywhere. That choice is denied to me in Firefox on my phone.

I love this typeface and I’m using it for a lot of stuff @ MNT, including the Reform brand. And it’s also pleasant as a GUI font on Linux desktops.
[+] argimenes|7 years ago|reply
This is a beautiful typeface, but I can't tell capital 'I' as in Italy apart from lowercase 'l' as in 'lasagne'.
[+] rayalez|7 years ago|reply
I'm not a designer, but to my non-professional eyes this looks good.

Do you think this font would be a good choice for a text editor?

[+] 676339784|7 years ago|reply
I'd stick to monospace fonts for text editors
