Typochondria is a state of persistent anxiety among designers that they have selected a wrong typeface or font for their project.
“The condition is often paired with optical kerning disorder or the need to constantly adjust and re-adjust the space between letters.”
Don’t mix typefaces that are too similar to each other but don’t combine those that are too discordant, don’t confuse styles and eras, and don’t buy poor-quality fonts.
Other typography related disorders include:
Typophilia - An excessive attachment to and fascination with the shape of lettersâ€š often to the exclusion of other interests and object choices.
Typophobia - The irrational dislike of letterformsâ€š often marked by a preference for iconsâ€š dingbatsâ€š and — in real fatal cases — bullets and daggers. The fears of the typophobe can often be quieted (but not cured) by steady doses of Helvetica and Times Roman.
Typothermia - The promiscuous refusal to make a lifelong commitment to a single typeface — or even to five or sixâ€š as some doctors recommend. The typothermiac is constantly tempted to test drive “hot” new fontsâ€š often without a proper license.
