The Perfect Fit: A Guide to Your Custom Rei Design Piece
At Rei Design, every piece is custom crafted to reflect your unique style. We believe that comfort is just as essential as aesthetics; a perfectly fitted ring ensures you can enjoy your piece with ease and confidence.

To ensure your custom ring fits perfectly, please follow one of the methods below:
Method 1: Measuring an Existing Ring
If you have a ring that already fits the intended finger perfectly, you can determine your size by measuring its internal diameter:
1. Use a precision ruler (in millimeters).
2. Measure the inner diameter of the ring (do not include the thickness of the metal).
3. Compare your result with our sizing chart below.

Method 2: Measuring Your Finger
If you do not have a ring handy, you can measure your finger directly:
1. Wrap a thin strip of paper or non-stretchy string around the base of your finger.
2. Mark the point where the ends meet with a pen.
3. Measure the length against a ruler in millimeters. This is your finger’s circumference.
4. Use this measurement to find your corresponding size in our chart.
