Frequently asked questions
- What is the average tattoo size in inches?
- Small pieces are 1–3 inches (2.5–7.5 cm). Medium tattoos are 4–6 inches (10–15 cm). Large statement pieces are 7–12 inches (18–30 cm). Sleeves and back pieces are measured in body coverage, not inches.
- How big is a 3 inch tattoo?
- Roughly the diameter of a coffee cup lid — large enough for moderate detail but still discreet on the forearm or calf.
- How small can a fine line tattoo be?
- Most artists won't go below 1 inch (2.5 cm) on detailed designs — anything smaller blurs together within a few years.
