Knowing your ring size can be the difference between a ring that’s just right and a ring that slips and slides around your finger. If you don’t already know your number, we’ll teach you how get your ring measurements for the perfect fit.

In general, getting a good ring measurement is an easy process. Still, there are a few pitfalls to be aware of that can throw off your fit. These factors can impact your ring measurement:

It’s perfectly normal for fingers expand in the heat and shrink in cold. Measuring during colder, normal, and hotter temperatures can tell you how much allowance you need for a comfortable fit.

Taking a ring measurement fresh off your workout may not be the best plan. Exercising raises your body temperature, so you will get a larger measurement and end up with a loose-fitting ring.

Measure both the base of your finger and your knuckle. Why? This helps account for your ring being able to get over your knuckle and fit snug on your finger.

Already have a ring that fits perfectly, but don’t know the size? No problem! You can use tools, like our paper test, to find your measurement. Follow the directions on our printable Ring Sizer tool and easily match your ring with its size.

Rather start fresh with a new measurement? All you need is a piece of string, a marker and a ruler. First, wrap the string securely around your ring wearing finger and mark where the string overlaps. Line up the taut, but not stretched, marked string with a ruler for your measurement.

If you don’t have string at home, you can do the exact same method but with paper. All you need to do is cut a long strip of paper, wrap it around your finger, mark the overlapping sections, and measure. You can also try out printable paper test that tells you your size right on the paper you use to measure.
