Thighs and Calves: Thighs and calves are to your legs as biceps are to your arms: broad, muscular, and among the most manageable locations to get tattooed. Specifically, your outer thighs are the toughest, but discomfort can increase as you move inward due to sensitivity.
Ankles: Similar to collarbones and ribs, your ankles are another area with particularly prominent bones. If you're planning to get a tattoo directly over your ankle bone, be prepared for a similar level of pain. Slightly above or below the bone toward your heel can be a bit more mild, but keep in mind that the skin is still quite thin.
