When ordering a ring online, it can be difficult to know which size you need. With an EU ring sizer, you can measure your finger at home and get a clear measurement to use when choosing a ring size.
The ring sizer works like an adjustable band that tightens around your finger. When it fits snugly but comfortably, the arrow shows which size to choose. The EU size corresponds to the inside circumference of the ring in millimetres. A reading of 54 therefore corresponds to EU ring size 54.
Many UK retailers use letter-based ring sizes. If the retailer lists UK sizes, check its conversion chart before ordering.
The pack contains two ring sizers, one white and one black. Each ring sizer is approximately 11 cm long.
- Feed the narrow end through the buckle so that the ring sizer forms a circle with the numbers facing outwards.
- Slide the sizer onto the finger where you intend to wear the ring.
- Tighten it until it feels snug but comfortable. It should not pinch and should still pass back over your knuckle.
- Read the number indicated by the arrow.
- If the arrow falls between two sizes, choose the larger size.
Measure the same finger more than once if possible. Finger size can vary with temperature and time of day, and the same finger may measure differently on your right and left hands.
