Fonts are a way of customizing and associating a piece of text. In a genre like horror, font is an obvious way to inflect a producers desired effect. In the title sequence of the movie "Se7en" a rapidly shaking and spontaneous opening credits along with a thin, carved like font gives a creeping effect.

The font is also hand written, hand written texts can take on an inflection of the person writing it, both in their physical and mental attributes. For example, if the hand writing is erratic and spiky, that could should that the writer is impulsive, but if the writer is a rule abiding person who is OCD, the writing will probably be neat and orderly.

The most common fonts affiliated with horror are thin, creepy fonts and blood-like fonts. Colour is also essential in creating a horrific effect, usually using black, white, or red fonts appropriately, a bright, happy coloured font would detract from such a genre.
