Measure Ring Size

Ring Size Calculator

The perfect ring is more than just choosing the right style and gem, it's also about finding the right size. This guide will walk you through two simple methods to measure your ring size correctly. So, let's get started!

Method 1: Using a Paper Strip

STEP 1: Trim a slim paper strip. This method is ideal if you do not have a ring to measure with. The idea is to mimic the circumference of a ring using a strip of paper.


STEP 2: Circle the strip around your finger, ensuring a tight fit. Make sure it is snug but not too tight. You want to be able to get the "ring" over your knuckle.


STEP 3: Mark with a pen where the ends overlap. This will give you a clear line to measure against.


STEP 4: Measure the length from the end of the strip to the mark with a ruler. Be sure to measure in millimeters for the most accurate fit.

STEP 5: Refer to the table to match your measurement with the appropriate US ring size indicated in the right column. If you're between sizes, it's usually best to go up rather than down to ensure a comfortable fit.


EXAMPLE: Our measurement is 63 mm, which corresponds approximately to a US ring size of 10.5. This means if your strip of paper measured 63mm, you would order a size 10.5 ring.


Method 2: Measure an Existing Ring


An alternative method, if you have a ring that already fits you well, is to measure its inner diameter. Simply take a ring that fits you perfectly and measure its inner diameter on a ruler in millimeters. Check the corresponding size in the table below. This is a quick and easy way to find your ring size without having to do any calculations.


Remember, this guide is a tool to help you find your ring size. Everyone is different and these methods may not work for everyone. *Make sure you are measuring the finger you intend to wear the ring on. Fingers on your dominant hand tend to be larger than those on your non-dominant hand, so make sure you measure the right finger!

Hopefully, this guide has made finding your perfect ring size a little bit easier. Remember, it's not just about the style and the gem, but the perfect fit makes for the perfect ring!
