The Philippe Harold Ring Size Guide: How to Find Your Perfect Fit

Choosing a beautiful ring is one thing — making sure it fits perfectly is another. After all, a ring that’s too tight or too loose can take away from the joy of wearing it. Whether you’re buying an engagement ring, a wedding band, or treating yourself to something special, finding the right ring size is key.

That’s why we created this clear, practical ring size guide. With the tips below, you’ll learn how to measure your ring size at home, how to use a ring size chart, and how to make sure your ring fits just right — comfortably and securely.

Why Ring Size Matters

A well-fitting ring should slide easily over your knuckle but feel snug enough to stay in place during daily wear. If it’s too loose, you risk losing it. Too tight? You’ll find it uncomfortable — especially in warmer weather when fingers naturally swell.

That’s why accurate sizing is essential — particularly for engagement rings or bespoke pieces that you’ll wear every day.

How to Measure Your Ring Size at Home

There are a few easy ways to find your ring size at home, even without professional tools. Try one of the methods below:

1. Measure with a String or Paper Strip

• Wrap a thin strip of paper or non-stretch string around the base of your finger.

• Mark where the ends meet.

• Measure the length in millimetres.

• Use our ring size chart to find the corresponding size.

2. Measure a Ring You Already Own

• Choose a ring that fits the intended finger well.

• Measure the inside diameter in millimetres.

• Compare the result to our chart for an accurate match.

Pro tip: Measure your finger at the end of the day when it’s likely to be slightly larger. Avoid measuring when your hands are cold, as fingers tend to shrink.

Ring Size Tips You Should Know

• Your dominant hand is usually slightly larger. If you're unsure, always size for the hand you’ll wear the ring on.

• Wider bands tend to feel tighter. If you're choosing a wide band, consider going up half a size.

• Planning a surprise proposal? Ask a close friend of your partner, or discreetly borrow one of their rings to measure.

• Still not sure? It’s safer to size up — it’s easier to make a ring smaller than larger.

Ring Size Conversion: International Differences

Ring sizes vary from country to country. For example:

• In Belgium and most of Europe, sizes are based on the circumference in millimetres (EU sizing).

• The UK uses letters (A–Z).

• The US and Canada use numbers, often with half sizes (e.g. 6.5).

• Japan and Switzerland use their own unique systems.

Use our international ring size conversion chart to compare and find the right match, no matter where you’re shopping from.
