In the current discussions around fonts on the web, there is much confusion between the techniques. Most seem to think that TypeKit and .webfont are our only options. They are not, but the rest of the landscape is quite busy.

Things have been moving very quickly in the last three weeks, so let me break it down like this:

• Webfont services: TypeKit, fontdeck, Typotheque
• Proposals: EOT-Lite, .webfont, ZOT, webOTF
• Implemented standards: @font-face using EOT and TTF
• JavaScript-based font solutions: sIFR, Facelift, Cufón

The commercial webfont services players

While many have considered TypeKit as an alternative to .webfont, it’s just a smart implementation of CSS and JavaScript along with a shop and licensing model. I agree with Pablo Impallari who commented:

You don’t need typekit, .webfont or any other solution. You can start using real fonts on the web right now.

Typekit makes a somewhat complicated implementation drop-dead easy, but if you’ve used sIFR before, than I’m confident you can handle this on your own.

The licensing legwork that TypeKit is doing is a significant value-add and may be worth it for people who don’t want to deal directly with font resellers. I’m quite interested in how the smart folks at Clearleft expect to differentiate their competing service, fontdeck.

Typotheque and Kernest are also new entrants to watch, both created by font shops. Both seem to only license their own foundries’ typefaces, so their library size may end up being quite small, but I can say right now Typotheque’s offering looks strong.

At the same time, we’ve had web font services already: Fontburner and Flir Premium, but they never really gained popularity, so I’m surprised people expect such a different outcome from these new players.

The EOT-Lite and .webfont proposals

The general complaint from the type community around non-EOT @font-face is that the naked font is so accessible, anyone could trivially take it off a webserver and install it on their machine. These two proposals offer a “garden fence” approach to protection; it’s still quite easy to get inside and snag the font, but it’s harder than if there were no protection at all.

.webfont, the format proposed by Tal Leming and Erik van Blokland is a great compromise solution: basically a zip file containing both an xml file of metadata and the font. While it uses the same css @font-face syntax, and everyone seems to love it, having it work in all browsers is at least three years off.

EOT-Lite, on the other hand, seems to be covered much less in roundups to date. The basic idea is that it’s the same as EOT but without the two major complaints of the format: domain binding and MTX compression. (Interesting as, the compression’s patent owner is offering to free it up.)

The huge plus of EOT-Lite is that the format works, right now, in IE4-IE8. Adobe, Monotype, Microsoft and a cadre of type shops support it. Perhaps surprising for some, Mozilla is also quite involved in the EOT-Lite discussion, not only helping to define the spec, but also making a test build of Firefox that handles the new format.

ZOT is a new format proposed by Mozilla; essentially TTF with compression. It’s well considered, but as .webfont comes with the same advantages and already has a wave of support, I think ZOT is best left as an academic discussion. Oh, and Berlow’s OpenType permissions table – which would have been a great idea to have in 2000, but not now.

Update 2009.08.10: .webfont and ZOT merged their proposals. It’s now called WebOTF.

The @font-face standard

By my calculations, the current implementation (using EOT or TTF/OTF) covers ~70% of users. When Firefox 3.0 users upgrade to 3.5 that figure will increase to ~90% of users (I bet we’ll see that within six months). Things still do visually look a little different across browser implementations, but they currently work cross-browser and with fixes like forcing Cleartype on for web fonts in Firefox, render quality is improving steadily.

/* it's this easy: */
@font-face {
  font-family: 'Gentium';
  src: url(Gentium.eot); /* EOT for IE */
}
@font-face {
  font-family: 'Gentium';
  /* IE ignores this one because of the format value */
  src: url(Gentium.ttf) format("opentype");
}
h1,h2,h3 { font-family: 'Gentium', Tahoma, sans-serif;

I generally side with the concerns of type foundries here, rather than the Fuck The Foundries crowd. I want myself and other designers to have access to the best of typography, but understand the fonts used for Firefox/Webkit are a little too naked at this point. While we’re waiting for the rest of this to pan out we may see a new market of type designers that are comfortable with naked fonts (like David B?ezina), but I’m skeptical about the efficacy of that.

JavaScript-based custom font solutions

We’ve had sIFR for nearly 5 years and I’m glad we have, but we now have better options. After significant research I think Cufón is the best library in this space; it’s small, clever, and very performant. However, many foundries aren’t ready to license their typefaces for use with Cufon. Facelift is a great alternative here, as it doesn’t expose the font data to the browser (instead generating PNGs via PHP), thus very licensing-friendly.

These libraries will be useful in bringing custom fonts to older browsers (currently: Firefox 3.0, Chrome, and Opera 9), but still lack flexibility when it comes to rtl languages.

It’s also possible that they won’t be treated only as a fallback solution. If foundries remain unwilling to license for the naked @font-face implementation in Firefox and Webkit, we may have no choice but to use Cufón while we’re waiting for these browsers to adopt EOT-Lite or .webfont. In fact, Monotype’s web embedding EULA currently allows use with siFR and Cufón, as long as there is domain-binding.

Conclusions

I don’t think webfont services are the future, but I do think the landscape is hairy enough now to convince web developers to take the easy route by relying on a TypeKit or Fontdeck for their custom type. Taking advantage of the best techniques available isn’t insurmountable without a hosted webfont service, and I think we’ll see developers going it alone with their own implementations and licensing directly with the font resellers.

I believe EOT-Lite is the right direction for webfonts right now. It already works in the most stubborn browser, and since Firefox just released a test build with support for EOT-Lite, it’s looking more reasonable than ever. It’s also quite interesting that after the months of debate at the W3C surrounding Microsoft’s proposal of making EOT the standard, it took quite some time for the sensible proposal of EOT-Lite to emerge. I guess both sides had to soften a little. :)
