What is Considered a Fine Line Tattoo?

Technically, a tattoo is considered "fine line" if it is executed using a tight needle grouping, typically a 3 Round Liner (3RL) or smaller (like a 1RL). The diameter of the needles is often thinner than standard, using #08 (0.25mm) or #10 (0.30mm) gauge needles instead of the standard #12. Any design that relies primarily on these thin outlines for its structure, rather than shading or color packing, falls into this category.
