What Do I Need to Find My Ring Size?

Want to know how ring sizes are measured at home? All you need is a pen, scissors, a ruler, and either a flexible measuring tape, string or paper. The final piece of the puzzle is our ring size chart, which you can use once you’ve measured your finger. Don’t worry, it’s easy!

Pro Tip: String can stretch, so try not to pull them too taut. If you do, your measured ring finger size may be larger than your finger actually is, and any rings you purchase may be too big.


How to Measure Ring Sizes at Home

To find your size, first wrap the measuring tape (or string) around the base of the finger on which you plan to wear your ring. You want the string or tape to be snug, but not tight. Ideally the measuring tape should be cloth — if you are struggling to wrap a measuring tape around your finger, just switch to a string to ensure your measurement is accurate.

Use a pen to mark the tape where it overlaps or cut the small piece of string with scissors. Then, simply measure the string in millimeters, or note how many millimeters it took to wrap the measuring tape around your finger.


Finger measuring tips

If you are between sizes, order a larger size. We recommend measuring your finger three to four different times because the size actually fluctuates depending on temperature: It can be smaller the colder you are and more swollen if you're overheated. If you know your knuckle is on the larger side, you should order half a size bigger than what your finger alone indicates, otherwise you won't be able slide a ring into the right place.

Finally, compare your millimeter reading to our ring size chart to find your perfect Plenty ring size.
