Measure your own finger
Step 1: Measure your finger by wrapping a strip of paper or wide thread around it, leaving enough space to slide the ring over your knuckle.
Step 2: Mark the place where the paper strip meets and measure the length by using a ruler. This is the circumference of your finger, which corresponds to European ring sizing. E.g. if it measures 5,4 cm you should choose a size 54. If you fall in between sizes, we recommend that you choose the larger size.
As a rule of thumb, you can always remember that you will probably need a slightly bigger size if the ring is wide versus slim. If the ring is sleek and slim we recommend that you opt for a slightly smaller size eg. 0,5 size difference.
This method can be used to find the ring size of any of your fingers.
Please note: That the ring size can vary depending on the ring design and fit on your finger.
Measure your own ring
Measure one of your own rings using a ruler. Lay the ring on a flat surface and place a ruler on top of the ring. Measure the ring (inside diameter) on the widest part of the ring. When it comes to selecting the perfect ring size, precision is key, as even a few millimeters can make a difference..
Things to consider
The fingers on your dominant hand tend to be larger than those on your non-dominant hand, so keep that in mind when measuring for your ring size.
Cold weather can cause your fingers to shrink a bit, while heat or water retention caused by food or medications, can cause finger swelling.
Ring Sizing Tips
Here are a couple of tips on choosing ring size based on the ring’s design/style.
Large statement/cocktail rings: Keep in mind that broad/thicker ring bands (larger than 6mm) will fit tighter. It is better to choose half a size up when purchasing a thicker band, for the ring to be comfortable.
Stacking rings: When you buy slim stackers ensure a comfortable fit by picking a snug-fitting ring size (measure the finger you choose to wear the ring on).
