The Multi-size adjustable finger gauge is ideal for determining your ring size from the comfort of your own home. Such a great piece it saves time by helping to avoid unnecessary returns due to inaccurate ring sizing. The reusable plastic finger gauge measures U.S. sizes 1–17 in half-size increments; the increments are clearly marked.
The multi-sizer works like a belt. Simply push the end through the buckle to form a ring shape. Slip the multi-sizer onto your finger. Adjust to give a comfortable fit, checking that it just slips back over the knuckle. When best fit is achieved, read off the size indicated by the arrow.
