Trillian started out in just one size. Then I got into a discussion about how it makes font designers sad when people stretch their fonts taller, or squash their fonts shorter, because it makes the horizontal strokes off-balance. So I said to myself, "Self, why don't you make a couple of additional heights of Trillian? So if people want it a little taller or shorter, they have it already in hand?"
Then I said to myself, "Self, those good folks could also use all three alphabets together! They can mix and match for a fun varying-height design, and everything would go great together because all three sizes share the same line weights!"
Then I stopped talking to myself, because people were starting to stare.
And so, the three heights of Trillian were born! Regular, Taller, and Shorter. Each size is a complete font on its own, but they also work great when they're working together. Each file also includes a full set of over 300 extended Latin characters for language support.
(And yes, the name Trillian is an homage to the late, great Douglas Adams.)
