Looking through various lists of fonts and font alternatives on another area of Ralf's site, I found in a list of free fonts Cormorant. I knew of Cormorant previously -- in fact, I have it in my font downloads and I like it, but I haven't installed it. Why not? Because I'm confused by it.

Cormorant is a serif typeface. However, if you follow the link to download it you find Cormorant, Cormorant Garamond, Cormorant Infant, and Cormorant Upright. (There are also small caps and unicase variants, but those are specialized.) Of the four I singled out for mention -- what's the difference?

This page does a good job of laying out the typeface and all its variants.

From the site:

Cormorant fonts come in three distinct master styles: The classic Cormorant Roman, the matching true italics Cormorant Italic, and an unslanted cursive named Cormorant Upright. Furthermore, four variant styles of the Roman are offered to make the most important OpenType alternate features readily available to users without OpenType-savvy applications: Cormorant Garamond, which offers larger counters and subtly more traditional Garamond shapes for a few key characters to achieve more reading comfort, Cormorant Infant, in which the letters «a g y» and their derivatives are replaced by gentle schoolbook-style single-storey shapes; Cormorant SC, in which the lowercase glyphs are replaced by small-caps; and Cormorant Unicase, a small-caps variant with some lowercase letterforms for an eye-catching futuristic look.

Each style is available in a range of five weights: Light, Regular, Medium, Semibold, and Bold.

Thank you. It looks like for book body text the choice would come down to Cormorant Roman or Cormorant Garamond.

When do you think Cormorant Infant might be the better choice?

As the name suggests, infant versions of typefaces are most often used for texts aimed at gradeschoolers/children in the midst of learning to read.
