This is a big collection of tattoo fonts. You can also use these fonts for creating logos.
Tattoo is a modern art but it has groomed so much that it is easier to define its patterns and make fonts basing on them. So font makers did that.
These tattoo fonts do make awesome tattoo designs but of course, you can create any kind of design with them. Apart from logos, they look catchy so you can use them on billboard designs, print media designing and animated banners etc. but one thing you should keep in mind that these fonts can never carry a serious or business feel.
So don’t use them on corporate style designing. For everything else, there’s a tattoo font.
Here is a collection of free tatoo fonts.
