Understanding Stroke Length for Coil & Rotary Tattoo Machines – A Complete Guide
In tattooing, every detail influences the final result, from the choice of needles and ink to the machine’s setup. One element that often determines the clarity, depth, and consistency of your work is stroke length. Selecting the right stroke length not only affects the precision of lines and smoothness of shading but also impacts how the tattoo heals. This guide explains what stroke length is, why it matters, and how to choose the right setting for your style, helping artists achieve the best possible results with their machines. What is Stroke Length? Stroke length, also called “throw,” is the distance a tattoo machine’s needle travels in a single cycle. In coil machines, it’s the movement of the armature bar before it drives the needle forward. In rotary machines, it’s determined by the rotation of the cam wheel, which sets how far the needle extends. Though measured in just millimeters, this distance plays a critical role in the speed, force, and overall performance of the ma...
