Precision Comfort
Ring & Jewelry Size Guide
A properly fitted ring should slide smoothly over your knuckle with light resistance, settling comfortably at the base of the finger without spinning.

Method 1: Measure An Existing Ring
If you or your partner currently own a ring that fits the intended finger:
- Select a ring that fits comfortably on the exact finger you intend to adorn.
- Use a millimeter ruler to measure the straight inner diameter from one interior edge across the center to the opposite interior edge.
- Do not include the outer metal thickness. Match your millimeter reading to the table above.
Method 2: Measure Around The Finger
If you do not have an existing ring available:
- Wrap a strip of non-stretching paper snugly around the base of your finger and across the widest part of your knuckle.
- Mark where the paper overlaps with a fine pen.
- Lay the strip flat against a metric ruler to read the circumference in millimeters.
- Always size up if between two sizes, especially for wider bands (over 3mm).
