Ring Sizing Questions and Answers

Existing Ring Mode draws a real-size diameter guide on your phone. Matching a standard card edge tells the app how screen pixels relate to millimetres on that display. Calibration does not change the chart or decide your size; it makes the on-screen circle usable.

Use the inner diameter: measure straight across the empty opening inside the ring. The outer diameter includes the metal band and does not represent the space that fits the finger.

Diameter runs straight across the inside of a ring. Circumference runs around a finger or ring. Existing Ring Mode and a known ring measurement use diameter; the paper-strip method uses circumference.

Use a ring that already fits the same finger when you have one. A paper strip is the practical alternative when you do not. The strip result depends more on how snugly the strip was held, so repeat it before buying.

Recalibrate before using Existing Ring Mode. The app saves calibration locally and checks browser/display-scale information. When that information changes, it treats the saved match as stale instead of continuing with a potentially wrong on-screen circle.

This tool shows the India, US, UK and EU labels stored together in its shared chart. A jeweller or manufacturer can use a chart with slightly different equivalents or fit expectations, so compare with the seller’s guidance for an important purchase.

Yes. Every matched chart row includes an India label, plus US, UK and EU labels. The Indian chart and India calculator place that result first, while still showing the same underlying dimensions and international equivalents.

For a diameter or circumference you enter, the calculator finds the nearest value in the shared ring-size chart and shows that row’s labels. It does not create a new size outside the supported chart.

Measure again, check whether you used the correct finger and method, and consider the ring’s width and your preferred fit. For an expensive, custom or non-resizable purchase, confirm the final choice with a professional jeweller.

A wider band can feel different from a narrow one even when the nominal size label is the same. The tool cannot judge that preference, so use the seller’s guidance or a professional fitting when band width matters.

Saved sizes and calibration are stored in your browser on this device. The app has no account or login for this feature. Clearing browser storage or using another device will not carry those locally saved entries over.

Use the result as a starting reference, then confirm it professionally. A browser-based measurement cannot account for every brand-specific tolerance, ring profile or wearer fit preference.

The most useful discreet reference is a ring the recipient already wears on the intended finger. Measure its inner diameter if you can; otherwise treat any estimate cautiously and review the seller’s resize or exchange options before purchase.

Yes. Sellers can share the measurement link from customer conversations, product pages, packaging inserts or QR codes. The result remains an estimate, so it should support—not replace—the seller’s own sizing guidance.
