Find your ring size
Measure on screen using a coin for scale, or enter a measurement you already have. We'll convert it to Indian, US and UK sizes at once.
Step 1
Calibrate to your screen
Choose a coin you have on hand, then place it flat against your screen over the circle below. Drag the slider until the circle exactly matches the coin's width.
Manual entry
Enter a known measurement
Wrap a strip of paper or string around the base of the finger, mark where it meets, and measure that length with a ruler — or measure the inner diameter of a ring that fits well.
