Measure a Ring You Own
Choose a ring that fits the intended finger comfortably. Measure its inside diameter in millimetres, from inner edge to inner edge, then match that measurement to the chart below.
Angelica Jewellery Guide
Find Your Perfect Ring Size
A beautiful ring should feel as exceptional as it looks. Use this guide to measure with confidence and discover a secure, comfortable fit.
Measure Your Finger
Wrap a narrow strip of paper or non-stretch ribbon around the base of your finger. Mark where the ends meet, lay it flat and measure the length in millimetres. This is your finger circumference.
Confirm the Fit
Your ring should pass over the knuckle with light resistance and rest securely without pinching. When a measurement falls between two sizes, the larger size is usually more comfortable.
For the Most Accurate Result
Measure twice, at the end of the day, when your hands are at a comfortable temperature. Measure the exact finger and hand on which the ring will be worn.

Use Our Printable Ring Sizer
For a true-to-scale result, print the appropriate Angelica guide on US Letter paper at 100% or Actual Size. Never select “Fit to Page.” Use the credit-card calibration line before measuring.
Gather Your Essentials
- Access to a printer
- US Letter paper (8.5 × 11 inches)
- A standard credit card for scale
- Scissors for the optional paper sizer
Print Your Guide
Choose the guide that best matches the expected size range. Print at 100%, then place a credit card against the 85.60 mm calibration line.
Measure and Find Your Size
Match a well-fitting ring to the printed circles or cut out the paper sizer and wrap it snugly around the intended finger. Read the US/Canada size and confirm it using the chart.
Method One
Match Your Current Ring to Our Chart
- Select a ring that fits the exact finger on which the new ring will be worn.
- Place it over the printed circles. The ring’s inside edge should align with the circle’s outside edge.
- If it falls between two sizes, select the larger size or contact us for professional sizing.
Method Two
Create Your Own Ring Sizer
- Gather: a narrow strip of paper or non-stretch ribbon, scissors, a pen and a millimetre ruler.
- Measure: wrap it snugly around the finger base, mark the overlap and measure the length in millimetres.
- Find your size: match that circumference to the conversion chart below.

A Thoughtful Surprise
Gifting a Ring Without Knowing the Size
- Borrow a ring worn on the same finger and have its inside diameter measured.
- Ask a trusted friend or family member who can find out discreetly.
- Trace the inside of a well-fitting ring on paper as a useful reference.
- When exact sizing is unavailable, ask us which styles allow future adjustment.
Average sizes can help with an estimate, but they do not guarantee a proper fit. Size 6 is a common starting point for women and size 9 for men in North America.
Expert Guidance
Important Sizing Considerations
- Fingers can change size with temperature, hydration and time of day.
- If your knuckle is wider than the base of your finger, consider both measurements.
- Bands wider than 4 mm often feel tighter; a half to one full size larger may be preferable.
- Several stacked bands fit like one wider ring and may require extra room.
- Eternity bands and highly detailed rings can have limited resizing options.
