How To Convert Your International Ring Size

Don’t know how to convert ring size for a snug fit that enhances comfort. This blog is for you.

Across countries, the standards for measuring ring size vary. But the good thing is that we can convert these markers by utilizing certain steps.  With that said, the simplest way to convert ring size is to use a plastic ring sizer and a standard size chart.

At Rings by Pristine, we help you convert your ring size from one country to another with both a ring sizer and a standard size chart.

In this blog, we have discussed both methods in detail so you can move forward with confidence when buying the perfectly sized ring.

How to Convert Ring Size: Complete Guide

Here we’ll break down how to convert your international ring size and achieve the perfect fit.

How to Find Your Ring Size

To find your perfect ring size, use a string or paper strip to measure your fingers' circumference at the base, mark where they meet, and then measure the width in millimeters with a ruler and compare it to a standard ring size chart.

For the most accurate result, measure your ring size at the end of the day, when your fingers are largest. If possible, visit a jeweler.

How Ring Size Differ Across Countries

There’s no single global standard for ring sizing. Instead, different countries developed their own systems over time.

Here’s how it breaks down:

• US & Canada: Use numerical sizes (e.g., 6, 7, 8)
• UK, Ireland & Australia: Use alphabetical sizes (e.g., L, M, N)
• Europe: Uses internal circumference in millimetres (e.g., 52, 54)
• Japan: Uses a numerical scale, but it is different from the US
• India: Often follows US sizes, but local variations exist

How to convert ring size between countries

Let’s get practical. When learning how to convert ring size, the key is understanding what’s actually being measured.

1. Know Your Current Ring Size Accurately

Before converting anything, you need a reliable starting point. You can:

• Visit a local jeweler for professional sizing
• Measure an existing ring’s inner diameter
• Use a printable ring size chart

Accuracy matters. Even half a size can make a big difference in comfort.

2. Use a Trusted International Ring Size Chart

Once you know your base size, match it against an international conversion chart. For example:

• US Size 7 ≈ UK Size N ≈ EU Size 54 ≈ Japan Size 14
• US Size 9 ≈ UK Size R ≈ EU Size 59 ≈ Japan Size 18

These charts are essential tools when converting ring sizes from US to UK, US to EU, or any other combination.

Quick Tip: Always use charts from reputable jewelers, not random internet images.

3. Consider Ring Width & Style

Here’s something many guides skip. Ring width affects fit.

• Wider bands feel tighter.
• Comfort-fit designs feel slightly looser.
• Inlay materials (wood, meteorite, ceramic) can change how a ring sits

If you’re between sizes, sizing up slightly is often safer, especially for wider bands.

Get a Ring Sizer By Rings By Pristine for Accurate Size

At Rings by Pristine, our plastic ring sizer is a jewellery-grade ring size tool that makes determining a ring size a breeze.

1. Take a look at the ring inserts and pick the one that will fit around your finger perfectly.
2. Slip the plastic ring onto your finger and give your hand a shake to ensure the fit is good.
3. If it’s too loose or too tight, we recommend trying a half size up and a half size down as well to find your precise fit.

The right size should be snug enough so the plastic ring won't fall off, but loose enough to slide over the knuckle.
