# Ringsize

### 1. You already have a matching ring

If you already have a matching ring, you can measure the diameter and calculate the circumference of the ring. Measure the inside diameter of the ring with a measuring slider or a precise ruler / scale / tape measure.

### 2. Measuring ring size without ring

If you do not have a ring, that's no problem. In this case, you can measure the circumference of your finger with a tape measure, or a piece of paper. Cut out a thin strip of paper and tie it around your finger so that it sits comfortably on the finger. Make sure that you measure the right finger at the right place - exactly where the ring would sit. Mark the spot on the paper and measure the length with a ruler.

The measured circumference corresponds to the ring size!
