Graffiti can have different styles. Tagging is the simplest type of graffiti, usually done quickly in spray paint, markers or pens and lacking artistic form; A throw-up involves more work than tagging, usually having two or three colors and done in bubble letters; Stenciling can be a quick way to produce more complicated graffiti designs and by using two or more layers, you can produce color-rich designs; Wildstyle is a form of graffiti that was made popular by graffiti artists like Tracy 168, Zephyr in NYC. Graffiti in Wildstyle is relatively more complicated and artistic. There are other forms of styles such as blockbuster, hip-hop, heaven, stickers, wheatpasting etc. So there are really a lot of styles of graffiti, hence, graffti fonts.
Depending on your preferences, there are many fonts that can be used for graffiti purposes such as bubble fonts, stencil fonts, outline fonts etc. However, for complicated graffiti styles, they can never be achieved by fonts. Graffiti fonts can be a good way to study graffiti letters or graffiti alphabet, but you really should learn to express in your own style.
