Your screen is zoomed in. Pinch to zoom out fully so the sizes stay accurate.
Step 1: Set up your screen
Screens come in different sizes, so we need to match yours once. Hold any debit, credit or ID card upright against the box below. Move the slider until the box is exactly the size of your card.

Keep your browser at 100% zoom. You only need to do this once on this device.
Step 2: Measure your ring
- Place a ring that fits you well flat on your screen, over the circle.
- Use the slider until the outer edge of the gold line sits exactly along the inner edge of your ring. The circle should fill the hole of the ring, without covering the metal band.
- Look straight down at the screen, not from an angle.
- If you're between two sizes, choose the larger one.
Size 15
17.5 mm diameter · 55 mm circumference
For the most accurate size, you can also measure the inner diameter of your ring with a ruler and match it to the chart below.
