💬 Contact Us About Ring Size Calculator Help
Our Contact Us page is the best place to send questions about the online ring size calculator, ring measurement methods, size-chart interpretation, international ring size conversions, accessibility, technical problems or content feedback.
Before sending a sizing question, it can help to include the measurement you used, whether it was inside diameter or finger circumference, the unit you measured in, and the sizing system you need. That extra context makes it easier to understand what may have caused a different result.
Online tools are useful for estimating a ring size, but they cannot physically check finger shape, knuckle width, band width or the fit of a particular design. For a high-value engagement ring, wedding band, custom piece or a ring that cannot easily be resized, professional sizing remains the safest final step.

Before Contacting Us About a Ring Size
Three quick checks can make a sizing question easier to understand.
Check the measurement type
Confirm whether your number is finger circumference or the inside diameter of a ring. These measurements are not interchangeable.
Include the exact unit
State whether the measurement is in millimetres or inches. A missing or incorrect unit can completely change the calculated size.
Name the sizing system
Tell us whether you need a UK letter size, US/Canada number, European measurement or a comparison with a retailer's chart.
Explain the difference you noticed
If another chart gives a different answer, include that value or source so the comparison is specific rather than general.

How to Get Useful Help From Our Contact Page
A short but specific message is usually more useful than a long message without measurements. If your question is about the online ring size calculator, start with the number you entered and say whether it represents circumference or diameter. Then mention the unit and the size result you expected.
For example, a question that says “I measured 54 mm around my finger and I am trying to compare the result with a UK size” gives much more context than simply asking “What is my ring size?” It also helps to mention whether the ring is intended for the left or right hand, because the same finger can differ slightly between hands.
Why Ring Size Answers Can Differ Between Websites
Ring size conversion is not always perfectly identical across every retailer or chart. Published tables may round measurements differently, brands may offer different half-size increments, and some retailers use their own conversion references. Band width, finger shape and how tightly a person measures can also affect the practical fit.
If you are contacting us because two charts disagree, include both values. We can review the calculation method and explain why the difference may exist, but the retailer selling the ring should remain the final reference for its own stock and sizing policy.
When to Contact a Professional Jeweller Instead
An online ring size calculator is useful for planning and comparison, but it cannot physically test how a ring moves over your knuckle or sits at the base of the finger. A jeweller can use physical sizing rings and account for details such as a wide band, comfort-fit interior, unusually prominent knuckles or a design that is difficult to resize.
The Gemological Institute of America provides professional jewellery education and consumer information. For broader jewellery learning, you can visit the GIA website. Technical standards for ring-size designation also exist internationally; the ISO 8653 ring-size standard is a useful external reference when researching measurement conventions.
Reporting an Error or Suggesting an Improvement
We welcome specific feedback that can make sizing tools easier to use. If you notice a broken link, unclear instruction, questionable table value, mobile display issue or calculator behaviour that seems inconsistent, send the page name and describe exactly what you observed.
Screenshots, device details or the values used in a calculation can be helpful for technical reports. For content corrections, include a reliable reference where possible. This makes it easier to distinguish between a genuine data issue and a normal difference between retailer sizing charts.
Privacy When You Contact Us
A general contact form should collect only the details required to understand and answer a message. Never send passwords, payment-card numbers or other sensitive credentials through a basic website support form. A ring-sizing question generally needs only your measurement, unit, sizing system and a description of the issue.
