How to use our Digital Ring Sizer
Step 1: Calibrate Your Screen
Use a credit card or a ruler to calibrate your screen’s dimensions.
Credit Card: Align the top of your card with the top of the dotted line and adjust with the plus (+) and minus (-) buttons until the bottom line matches the card’s bottom.
Ruler: Align 0 on the ruler with the 0 on screen and adjust with the plus (+) and minus (-) buttons until the numbers match.
Step 2: Measure Your Ring
Place your ring on the grid and adjust with the plus (+) and minus (-) buttons until the arrows just touch the inside edges of your ring.
Once aligned you have your ring size!

Our UK ring size conversion chart is designed to help you find your ring size at home. Just measure the ring size circumference of the finger you will be wearing the ring on, using a tape measure. Then use the ring size conversion chart to get your ring size and convert it.
