Your Problem

Online ring shopping gets risky when size is unknown

Most buyers either guess, visit a store, print a chart, or send a seller a vague WhatsApp message. Each step adds friction and uncertainty.

Guessing size before an online jewellery order

Printable charts that need a printer and perfect scaling

Paper strips that are pulled too tight or too loose

Confusing international size conversion tables

FAQ

Common ring sizing questions

Digital measurements are helpful estimates. For expensive jewellery, final confirmation from a professional jeweller is recommended.

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.
