Font formats

OpenType myths explained

OpenType ist the standard font format of these days. But even 14 years after its introduction, many users don’t really know what the term OpenType implies and how it differs from other font formats. Since I use the domain opentype.info for my weblog, I thought it is time to shed some light on this confusing subject …


Understanding Font Formats


After doing mostly web work for a few years, I've recently started doing more print work. I'm trying to get a better understanding of typefaces and their formats. I use Suitcase Fusion to manage my fonts and I'm a bit perplexed by the Type (font format) column.

For example, when I load Gotham, the Type column says: OpenType-PS

There is also Gotham Thin categorized as OpenType-TT.

I thought that type could be either Open Type, True Type, or Post Script, but the above indicates that the font is both OpenType and True Type. Could someone give me some tips on how to read these formats and how to decide which one to use?
