RING SIZING

Ring Size Guide

Find your US ring size, compare physical measurements, convert to the closest UK size, or print our actual-size sizing tools.

FOR THE BEST FIT

These sizing tools are intended to help estimate your ring size and are not a substitute for professional sizing. For the most precise measurement, we recommend having your finger sized by a local jeweler. Many jewelry counters, including those at major retailers such as Walmart, will typically check your ring size at no charge.

International labels do not align perfectly between published charts. Use the millimeter measurements as the physical reference; UK sizes shown are the closest equivalents.

METHOD 1

Use a Ring You Already Own

Choose a ring that fits the intended finger well. Print the chart below and place the ring over the circles. Match the inside edge of your ring to the outside edge of the sizing circle. This is the preferred at-home method when you already own a well-fitting ring.

METHOD 2

Use the Pull-Through Sizer

Print and cut out the CoinCrafters sizing strip below, cut the marked slot, then feed the pointed end through it. Wrap it around the finger so it is snug but can still pass over the knuckle. Read the US size at the slot. For an important purchase, a jeweler's physical sizing gauges remain the best confirmation.

Coin rings are wide bands. Wide bands can feel more snug than narrow rings. Do not automatically add a half size: use a similarly wide ring when possible, or have a jeweler size you with a wide-band gauge. Measure at a normal, comfortable hand temperature.

PULL-THROUGH FINGER SIZER

Cut around the outside edge. Cut the vertical slot. Feed the pointed end through the slot, numbers facing out, and read the size at the slot.
