Finding Your Ring Size
The ring sizes on our website are listed in US sizes. If you already know your EU size, please refer to the Ring Sizes Chart to find the corresponding US size. If you are not sure, feel free to contact me at info@eviapostoloujewellery.com
For the most accurate measurement, we recommend visiting a local jeweler or jewelry store to have your finger sized. If that’s not possible, you can easily determine your size at home using one of the methods below.
Method 1: Measure Your Finger’s Circumference
- Wrap a piece of paper or string around the base of your finger (not too tight—aim for a comfortable fit).
- Mark the point where the ends meet.
- Measure the length of the paper or string against a ruler (in millimeters).
- Match your measurement to our size chart to find the right size.
Tips for best results:
- Avoid measuring when your hands are cold or swollen.
- Repeat the measurement 3–4 times for accuracy.
- Measure your knuckle as well to ensure the ring will slide on and off comfortably.
Method 2: Measure an Existing Ring
- Select a ring that fits snugly and has a perfectly round shape.
- Place the ring on a flat ruler and measure the inside diameter (in millimeters), excluding the metal itself.
- Match your measurement to our size chart to find the correct size.
