Finding a size that actually fits.
Three ways to measure — pick whichever you have time for. Every Mohana Jewels ring can also be resized after purchase, so there’s no wrong answer, just a better starting point.
Ring sizing is deceptively tricky.
A size is just a number, but a finger is a living thing — it expands and contracts through the day, with the weather, with what you ate. Most people sit between half a size and a full size of difference between morning and night.
Our best advice: measure when your hands are warm and your body is at rest, aim for the widest part of your finger (the knuckle), and remember that a well-fitting ring should slide on easily and need a small twist to come off.
Measure a ring you already own
Place a ring that fits you well on top of your screen, then adjust the circle below until it matches the inside of your ring. We’ll convert the diameter into sizes across regions.
International size conversion
If you already know your size in one system, find the equivalent here. All sizes reference the inner diameter of the ring in millimetres.

Print at home
Two methods depending on what you have. Print at 100% / "Actual Size" — never "Fit to Page".
How to use:
- Cut along the dashed outline of the strip below.
- Make a small slit in the strip where marked (⊙) — the pointed end will thread through it.
- Wrap the strip around the base of your finger, snug but not tight.
- Thread the pointed end through the slit and read the number where it overlaps.
How to use:
- Print the page at 100% / Actual Size.
- Place a ring that already fits over each circle.
- Find the circle whose outer edge matches the inside of your ring. That’s your size.

Every Mohana Jewels ring can be resized after you receive it. Your first resize is on us, within the first year of purchase. After that, resizes are available at cost — because a ring should fit you for life, and fingers change through a lifetime.
