It is strongly recommended to order a ring sizer before ordering a ring. The cost of the ring sizer will be deducted from your ring- order.
The ringsizer helps you to determine your current ring size. I use identical ring-sizers in my workshop and can therefore work with the most accurate measurements on my ring mandrels with which I shape the rings.
Measure your ring size when your fingers are neither too hot nor too cold. It is best to measure them in the middle of the day.
Make sure you can slide the ring-sizer on and off comfortably while there is still some friction over your knuckles so that your ring doesn't fall off when your hands are a bit colder.
The table below shows the British and Dutch sizes.
