Two ways to measure: • Ring on screen — place a ring you already own on the display and resize the circle until it matches. • Finger on screen — line up the guides to your finger and read the size instantly. Calibrate once with any bank card for real-millimeter accuracy, then convert between US, UK, EU, Japan, China and Russia sizing — by diameter or circumference, in mm or inches.

Note: on-screen measuring depends on your screen; calibrate with a card and measure twice for best results.
