Ring Size Guide

Finding the right ring size ensures your BOO piece feels comfortable, secure, and effortless to wear. Use the guide below to choose your size with confidence.

How a Ring Should Fit

A ring should slide onto your finger smoothly and feel secure once worn. It should be slightly snug when passing over the knuckle, but not tight or uncomfortable.

Your ring should not leave strong marks on the skin, rotate too loosely, or feel difficult to remove.

Use the measurements below as a general guide.

Measure an Existing Ring

The easiest way to find your size is to measure a ring that already fits well.

1. Choose a ring that fits the same finger you plan to wear your BOO ring on.

2. Measure the inside diameter of the ring in millimeters.

3. Compare the measurement with the chart above.

Measure only the inner opening of the ring, not the outside edge.

Measure Your Finger

You can also measure your finger using a thin strip of paper or string.

Wrap it around the base of your finger, mark where the ends meet, then measure the length in millimeters. For the most accurate result, measure your finger at the end of the day when your hands are naturally warmer.

Avoid measuring when your hands are very cold, as fingers can become slightly smaller.

Choosing Between Two Sizes

If you are between two sizes, we usually recommend choosing the larger size, especially for wider ring designs.

For thin and delicate rings, your usual size should feel comfortable. For wider or thicker rings, sizing up may provide a better fit.

Things to Keep in Mind

Finger size can change slightly throughout the day depending on temperature, humidity, and activity. Your dominant hand may also be slightly larger than your other hand.

For the most accurate fit, measure your finger more than once and compare the results.
