How to measure your ring size?
Whether you are planning to gift yourself or someone else with a nice ring & you don’t know the right size, we have you covered. Below, we have listed three ways to find out the correct ring size. For those who are planning to buy a ring as a surprise, we have you covered too!! Keep reading to find out some tips to help you find the right size & not spoil the surprise.
Measure an existing ring
You may use a ruler to measure the inside diameter of the ring. This measurement, expressed in mm, can be used to determine the correct ring size. Simply download our comparative table below to match the ring size chart we use. Match the last column (mm) with the first (METALLON).

If you already know the size in a different measuring system you can download our comparative table to match our system.
Print a paper ring sizer
You can print, cut and use this paper ring sizer to determine the correct ring size. Make sure you are printing in the correct scale. If the scaling is correct, this method is quite reliable.
Measure more than once
To eliminate an erroneous reading, it is best to measure the size up to 3 or 4 times. Bear in mind that the size can vary depending on the time of day, the weather and other temperature changes. Fingers tend to be smaller when cold (in winter) and tend to be swollen when warm (in summer, in the early morning, after wearing gloves,..).
When in doubt
It is easier to stretch the ring than to make it smaller. However, if you are planning a surprise proposal, you might rather choose a larger size than a smaller size. This way, you will be able to slide the ring around her finger after you have popped the question.
Consider the ring design
A wider ring needs to be slightly larger to ensure it is not too tight or causes a pinching sensation. Add 1 or more sizes for a comfortable fit. For very wide rings, it is best to contact us personally for expert advice.
The average ring size is 52
Most women have a ring size between 49 and 56. A ring should fit your finger comfortably. It needs to be tight enough so that it won't fall off, but at the same time, loose enough to slide over your knuckle.
Account for the knuckle
The base of your finger is often smaller than your knuckle. Make sure to measure both the base and the knuckle separately and select a size in between those two measurements. This will allow the ring to slide over your knuckle but still fit comfortably around the base of your finger.
Wrap a strip of paper underneath your wrist bone. Mark where the paper overlaps with a pen. Measure the length from the edge of the paper to the mark with a ruler.
