Introduction
Rings are commonly sized in diameter, but they can also be sized in circumference. The two measurements are not equivalent. In order to determine your ring size in circumference, you will need to measure the inside diameter of a ring you already own and compare it to a ring size chart. To measure the inside diameter of your ring, use a ruler to measure the distance across the inside of the ring from one edge to the other. Once you have your measurement, consult a ring size chart to find your corresponding ring size in circumference.
The most common way to measure rings is by diameter, which is the distance across the inside of the ring. To measure your ring size in diameter, use a ruler to measure the distance from one edge of the inside of the ring to the other. Once you have your measurement, consult a ring size chart to find your corresponding ring size in diameter.
Ring sizes generally range from 3 cm to 9 cm in circumference, or 45 mm to 60 mm in diameter. The most common sizes are 7 cm and 8 cm in circumference, or 50 mm and 54 mm in diameter.
If you don’t have a ruler handy, you can also use a piece of string or ribbon. Wrap it around the inside of your finger and mark where it overlaps with a pen or pencil. Measure the length of the string with a ruler and consult a ring size chart to find your corresponding ring size.
How to Measure Your Ring Size
To measure your ring size, you will need a soft measuring tape and a pen. Wrap the measuring tape around the base of your finger. Make sure the tape is snug, but not too tight. Once you have wrapped the tape around your finger, write down the measurement. This measurement is your ring size.
Use a ring sizer
To find your ring size, use a flexible tape measure or a strip of paper and wrap it around the base of your finger. Keep the tape snug, but not too tight — you should be able to slip it off and on with only a little resistance. Once you have your measurement, refer to the ring size chart below to find your corresponding ring size.
If you don’t have a flexible tape measure or a strip of paper handy, you can also use a string. Wrap the string around your finger and mark the spot where it overlaps to form a complete circle. Then, use a ruler to measure the length of the section of string between the mark and the end. Once you have your measurement (in centimeters), refer to the chart below to find your corresponding ring size.

Measure your ring with a ruler
One of the most common ways to measure your ring size is by using a ruler. You can measure your finger in either centimeters or inches, but we recommend using metric measurements for more accurate results.
To measure your ring size using a ruler:
-Wrap a strip of paper or string snugly around the base of your finger.
-Mark the point where the two ends of the paper or string meet with a pen or pencil.
-Use a ruler to measure the distance from the beginning of the paper or string to the mark you made.
-Compare your measurement with our ring size chart to find your ring size
How to Convert Your Ring Size to Centimeters
To figure out your ring size in centimeters, you will need to know the diameter of your finger in millimeters. You can convert millimeters to centimeters by dividing the millimeter measurement by 10. Once you have the diameter of your finger in centimeters, you can use the chart below to determine your ring size.
Use an online ring size converter
There are a few different ways that you can convert your ring size from centimeters to inches or vice versa. You can use an online ring size converter, like this one from Blue Nile. Alternatively, you can use a ruler to measure the inside diameter of a ring that fits you well and compare it to a ring size chart.
If you don’t have a ruler or a way to measure the inside diameter of a ring, you can also wrap a string or strip of paper around your finger and mark where it overlaps. Then, use a ruler to measure the length of the string or strip of paper and compare it to a ring size chart.
Use a ring size chart
First, find a ring size chart like this one. You can also use a ring size conversion chart like this one. Place the chart on a flat surface and line the inside edge of the ring up with the correct circumference measurement in millimeters or inches. If you are using a U.S.-based ring size chart, you should line up the inside edge of the ring with the appropriate size in inches. If you are using a European or international ring size chart, you should line up the inside edge of the ring with the appropriate size in millimeters.
Conclusion
To recap, there are a few things to keep in mind when you’re trying to figure out what ring size is 7 cm. First, make sure you measure your finger correctly. Second, remember that ring sizes can vary slightly from country to country and from brand to brand, so it’s always best to try on a few different sizes before you buy. Lastly, if you’re still not sure what size to get, err on the side of caution and go for the larger size. It’s always easier to make a ring smaller than it is to make it larger.
