Tobias Frere-Jones illustrates the basic mechanics of type

The always inspiring Tobias Frere-Jones has started a new series of posts on the mechanics of type and so far it sounds perfect for the novice and expert alike.

This new series of posts will explore what I call “typeface mechanics”, the behind-the-scenes work that makes typefaces visually functional. It is what placates the stubborn oddities of human perception, helps or hinders the user, and informs long-standing conventions of design.

The first part is about vertical and horizontal position of type. Logically you’d think all the letters would line up perfectly though unfortunately our brains don’t work that way. Take a read and see for yourself.
