Needleteeth Suite: Free Fonts With Halloween Bite
If there is such a thing as a traditional Halloween font, Needleteeth could well be it. This razor-sharp TrueType outlines font collection from Chad Savage at Sinister Visions includes two variations, each in two alternating sizes: Regular, Psycho, Creepy, and Spooky. Both Creepy and Spooky include drips of what we should assume is blood. For the full shiver-inducing effect, mix-and-match the paired Needleteeth fonts to achieve the look you want.
All of the Needleteeth Suite fonts are solidly for display purposes---even Needleteeth Regular doesn't work well at sizes smaller than 24 point---and all are best for short, shocking statements. Needleteeth displays all uppercase, but includes lower case glyphs at a slightly different size. The font also includes numbers and common punctuation.
Needleteeth Suite is entirely free for personal and commercial use; all Savage asks is for you to send him examples of how you've used his font. A horror artist as well as a designer of creepy, spooky, spine-tingling fonts, Savage's work includes the Autumn Harbinger and Zombo-o-Lanterns desktop wallpapers.
