Finding the correct ring size is essential to ensure a comfortable, secure fit. A ring should slide easily over the knuckle and feel snug enough that it won’t fall off — but never too tight. Whether you’re measuring for yourself or planning a surprise, this guide makes it easy to determine the perfect size.

How to Measure Your Ring Size at Home

1. Use a Ring Sizer

The most accurate way to measure is with a professional ring sizing tool.

• Request a free ring sizer from us, or
• Purchase a plastic sizer online and measure using the numbered scale.

2. Measure a Ring You Already Wear

If you have a ring that fits the same finger:

1. Measure the inside diameter of the ring in millimeters.
2. Compare it to a standard ring size chart.

Inside Diameter (mm)	U.S. Size
16.5 mm	Size 6
17.3 mm	Size 7
18.1 mm	Size 8
18.9 mm	Size 9

We offer a full detailed chart with half and quarter sizes upon request.

3. Use the String or Paper Method

Wrap a thin strip of paper or string around the base of your finger, mark where it overlaps, and measure the length in millimeters.

Length in mm ÷ 3.14 = inside diameter (mm)
Then match the diameter to the chart above.

Helpful Tips for the Best Fit

• Measure at the end of the day — fingers are smallest in the morning and larger in the evening.
• Measure the finger on the correct hand — your dominant hand is usually slightly larger.
• Consider knuckle size — if your knuckle is bigger, choose the larger size.
• Wider bands fit tighter — you may need to size up for thick bands.
• Temperature matters — fingers shrink in cold weather and swell in heat.

Common Ring Size Questions

What is the average ring size?

The average ring size for women is 6–7, and for men is 9–10, but everyone is unique — measuring is always best.

What if the ring doesn’t fit perfectly?

Most rings can be resized. We offer first-time resizing on engagement rings and wedding bands for perfect fit and peace of mind.

Can you secretly find someone’s ring size?

Yes! Borrow a ring they wear on the same finger (left ring finger), trace it, or ask a friend or family member to help.
