How to easily find your ring size? (The Oetika method)

You want to know your ring size, but you don't have a ring sizer handy?
Good news: you can measure it at home with... a simple string, a cord, or even a small piece of paper.

At Oetika, we like simple, accessible, and hassle-free solutions.
Here is the most reliable method, tested and approved.

✨ The string method (or cord, or paper)

1. Prepare your materials

You will need:

  • A small string / a thin cord / a very narrow strip of paper

  • A pen (or a marker)

  • A ruler (millimeter scale)

  • And your finger, of course

(Spoiler: it even works if your fingers are swollen because you just ate noodles.)

2. Wrap the string around your finger

  • Choose the finger on which you want to wear the ring.

  • Wrap the string around the base of the finger, where the ring will actually rest.

  • The string should be snug, but not tight.
    You should be able to move it slightly.

👉 Oetika Tip: measure at the end of the day, fingers are always a bit more "true" than in the morning.

3. Mark the meeting point

When the two ends of the string meet,
make a small mark with a pen to indicate the junction.

This is the decisive moment.
(If you mess up, try again — even Beyoncé didn't get it right the first time.)

4. Measure the length

Lay the string flat on a table and measure the distance between the start and your little mark.

➡️ Note the length in millimeters (mm).
This is your finger circumference.

5. Find your size using the table

In France, a ring size simply corresponds to the circumference of the finger in millimeters.

Example:

  • 50 mm = size 50

  • 54 mm = size 54

  • 58 mm = size 58

Finger circumference = Ring size

Yes, it could have been more complicated... but it isn't (for once).

📌 A few Oetika tips

  • If you are between two sizes, choose the larger one, especially if you have prominent knuckles.

  • Finger size changes slightly depending on the time of day, heat, and activity: this is normal.

  • If you want zero stress: our adjustable rings are made for you.
