I'm looking to use Joesfin Sans. It's listed on Google web fonts. I also have the .eot, .svg, .ttf and the .woff. This means full compatibility with the files (as far as I know).
My main question is: which is better? Does Google Fonts load faster? Is it more compatible? Or should I stick with the files?
If you want the quick and easy solution, embed the font loader code and move on. Google is frequently adding more options/features to their service.
Personally, I prefer to download the files from Google and work with them manually. Since there is a Google UI specifically for downloading your selected fonts (and from reading the license agreement) I believe this is legitimate use, but I'm not a lawyer.
Why do I do this?
I have experienced latency when accessing Google fonts (200-300ms). While this isn't terrible, most of my server environments respond faster and a font is an important prerequisite for a page. Any benefit from hitting a separate domain (i.e. parallelization to different hosts by the browser) is lost.
I've manually trimmed the font files to remove all unwanted glyphs. This results in a smaller file size.
IE8 support--it appears the
.eotdoesn't always get downloaded.
These reasons are mostly anecdotal but I have been much happier managing the font files myself.
Using actual font files on your server is better in production because:
- It’s more robust. Consider what happens when Internet connections (from the user’s location) to Google servers do not work. Generally, don’t rely on remotely hosted services without good reason.
- It’s probably a little faster in the average.
- You are in control. Google has a long history of taking services down or changing them (e.g. to paid services).
- The way Google serves fonts has some bugs.
Naturally, you would need to do at least the same as Google does in an attempt to cover different platforms (with different font file formats).
