KEEP THESE IN MIND

Helpful Tips for the Best Fit

Measure at the end of the day

Your finger size may vary slightly during the day.

Keep it comfortable

Measure at room temperature, not when hands are very cold.

Consider wider bands

Wider bands may feel tighter than slim rings.

Compare with another ring

For reassurance, measure a ring that already fits.

FREQUENTLY ASKED QUESTIONS

Ring Size Guide โ€“ FAQs

What if my size falls between two sizes?

Measure again at normal room temperature. If it still falls between sizes, check the band width and choose the fit that feels comfortable.

Is the ring size the same for all countries?

Ring sizing systems vary. Use the country-wise conversion chart to compare India, US, UK, France, Germany and other listed regions.

Can my ring size change over time?

Yes. Finger size can change with temperature, time of day and other factors. Measure again if you have not worn a ring for some time.

Should I measure my knuckle or the base of my finger?

Measure around the base of the finger, and ensure the chosen ring will also pass comfortably over the knuckle.

What is the most accurate way to measure at home?

Use a well-fitting existing ring to check its inside diameter, or measure carefully using a flat strip of paper. Repeat the measurement to confirm it.
