Find Your Ring Size

Read our guide to learn how to find your correct ring size at home.

Ring Sizing Chart

All Billie Jo rings are measured in US sizing.

Sizing Tips

1. Our dominant hands are generally slightly larger (up to half a size), make sure you are measuring the finger on the correct hand.

2. Rings with wider bands will fit a bit tighter than those with a thinner band. If you plan to measure one of your partner's rings, try to measure one with a similar width as the ring you want to purchase.

3. Make sure the finger is at normal body temperature, fingers can shrink or expand when hot or cold.

4. Your fingers tend to change size throughout the day, the best time to measure your finger is the end of the day.

5. If your knuckle is bigger than the base of your finger, take a measurement of both and choose a size in between. The ring needs to fit over the knuckle but not be too loose or it will shift around.

6. If you are buying for someone else and you don’t know their size, selecting one of the standard ring sizes is your best choice. The average ring size for women is 7, and the average ring size for men is a 10.

Measure Your Ring Size at Home

1. Cut a strip of paper approximately 1cm wide and 10cms long.

2. Wrap the paper around the base of the finger you are buying the ring for.

3. Place a mark where the paper overlaps.

4. Measure this length in millimeters to find the circumference of your finger.

5. Next, head to our sizing chart to convert the measurement to US sizing.
