Nose Hoop Size & Fit Guide
Two numbers decide the fit. Gauge is the thickness of the wire, and most nose hoops are 20G with some 18G, so match what you wear now. Diameter is the real style choice. 5/16" hugs the nostril close. 3/8" gives the hoop some air and movement. Every product page lists both.
Each closure opens a different way. A seamless ring opens with a gentle sideways twist, like a key ring, and pulling it apart will bend it out of round. A hinged hoop clicks open and shut with one hand. A horseshoe has a ball that unscrews. Seamless looks cleanest. Hinged swaps fastest.
