Tattoo Needle Size Guide

Every needle configuration we make, what it does, and how to read the numbers on the box. Written by working tattooers, for anyone setting up their first station or trying a new config.

How to read a needle code

Needle codes follow the same pattern across the industry: diameter + needle count + configuration. Take 1203RL:

  • 12 = the needle diameter gauge (#12 = 0.35mm)
  • 03 = the number of needles in the grouping
  • RL = the configuration (round liner)

So 1203RL is three 0.35mm needles in a round liner grouping. A 1011CM would be eleven 0.30mm needles in a curved magnum.

Diameter

  • #12 (0.35mm): the standard. Most of our liners and shaders are built on #12.
  • #10 (0.30mm): also called bugpin. Thinner needles put down finer lines and softer, more controlled shading. Our tight liners and bugpin mags are #10.

Taper

The taper is the sharpened point of each needle. We make two:

  • Long, polished: a longer, finer point. Smoother lines and softer gradients. Used on our round, tight and hollow liners and our long taper mags.
  • Medium, textured: a shorter point with a textured finish that holds and releases more ink. Used on our bold liners and standard and bugpin mags for packing and saturation.
