How to measure your ring size? Simple methods to avoid making mistakes

Whether you're buying a piece of jewelry or treating yourself to a protective talisman, choosing the right ring size is essential. A ring that's too tight will be uncomfortable, while one that's too loose could get lost. Here are three simple ways to accurately measure your finger size.

1. 📏 Measure the diameter of a ring you already wear

• Take a ring that fits you well.

• Lay it flat on a ruler.

• Measure the inside diameter to the nearest millimeter (do not take the edges).

• Refer to a correspondence table (for example, a diameter of 17 mm = size 54 FR).

👉 This is the fastest method if you already have a ring in your size.

2. 🧵 Use a thread or a strip of paper

• Cut a small ribbon of paper or thin wire.

• Wrap it around the base of your finger, without tightening too much.

• Mark where the ribbon crosses.

• Unroll and measure this length: this is your circumference.

• Enter this measurement in a table (e.g.: 57 mm circumference = size 57 FR).

✅ Tip: Measure your finger at the end of the day, as fingers can swell slightly.

3. 📐 Use an online ring sizer or a plastic ring sizer

• Some sites offer printable ring sizes or physical plastic ring sizes.

• Simply place a ring on it or try the sizes directly.

• This method is reliable, especially if you are between two sizes.
