What ring size am I?

1. If you have a ring with which you can validate the size, we recommend two options:

Take the diameter of your ring directly with a ruler. If you already have a ring that fits you well, you can measure the ring size directly with a ruler. Just take the ruler and measure the center of your ring, from inner edge to inner edge. It is very important that when taking the measurement you place the ruler cutting the ring in half , to take the measurement of the widest section of the circumference.

How do I measure my ring?

Remember to place the ruler or tape measure cutting the ring in half

Then measure the inner diameter of the ring, considering only the inner measurement of the hoop, as this information will match the size you need.

Then use our detailed "Peru Ring Size Guide" measurement chart below to find out your ring size. If your measurement is between two sizes, we recommend choosing the larger size.

For example: If your measurement is 49 millimeters, your ring size would be 5.

If you would like to perform a double validation Open and print our ring size guide PDF here and follow the directions included in the document.

2. If you do not have a reference ring, you can validate your ring size by measuring the circumference of your finger. You can follow these steps: Measure your finger by placing a piece of string or a very thin piece of paper over your finger. Once you have measured your finger, you must use a ruler to validate the number of millimetres in length of the string or paper to find out the actual circumference of your finger. With this information, validate the ring size that corresponds to you in the "Ring Size Guide" detailed below. If your measurement is between two sizes, we recommend choosing the larger size.

For example: If your measurement in millimeters is 45.4, then your ring size is 3 ½.
