Method 1: Print a page
Each circle corresponds to the inside diameter of the ring, while the number in the middle is the circumference.
So to find the desired ring size you can print this page at 100% scale. Then, you can use a ring that you have and it is the size you want, compare it with the diagram to find the corresponding diameter. Note that the inside size of the ring is required.
In case you are between two sizes, we advise you to choose the larger size.
Method 2: Measure perimeter or diameter
When trying to find the size for your ring it is important to keep in mind that:
Your hands are probably not the same size.
Your “good” hand is usually slightly larger.
This practically means that if you know the size of a ring you wear on one hand it may not fit your other.
A ring is preferably slightly larger than normal than smaller.
That is, if your measurement is between two numbers, it is better to choose the larger one.
Your fingers may be a little swollen during the day or on warmer days.
Do not forget to take into account the size of the joints through which the ring should pass.
Here are two ways to find the ring size you are interested in:
Measuring the perimeter
Wrap your finger with a thread to create a complete circle around it.
Use a pencil to mark the point where it meets its tip on the tape measure or the thread.
Open the tape measure or the thread in a straight line (alternatively you can cut the thread with a pair of scissors so that the net perimeter remains.
Measure the length of the thread in millimeters (mm).
Record your measurement and by looking at the table below find the size of the ring corresponding to your finger.
Measuring the diameter
If you have a ring that you are already wearing and you are satisfied with the size and if the ring you want to buy is for the SAME finger proceed with the following procedure:
Put the ring on a ruler or a measuring tape as in the photo.
Measure the net diameter in the middle without the material at the edges.
Record the measurement by measuring your length in millimeters (mm) and refer to the table below to find the size of the ring that corresponds to your finger.
