How to Measure Your Ring Size with String, Paper, and a Ruler

If you are wondering how to measure your ring size at home, there are creative steps you can follow to find the right fit. When buying for someone else, the best way to find their size is to ask them directly. If you’re planning a surprise, ask friends and family for help. They can inquire without raising suspicion. You can also use our printable sizer to measure their existing rings and find their size.

There are also several ways at home to find your ring size or the size of a gift. These methods require a few simple tools, such as a piece of string, a ruler, a pen, and a piece of paper. The home measurement method may also involve a quick calculation to find the numerical size.

Measure Your Ring Size with These Steps:

1. Wrap string or paper around the base of your finger.
2. Mark the point where the ends meet with a pen.
3. Measure the string or paper with a ruler (in millimeters) and then divide by 3.14 (or Pi) to find the diameter of the ring.
4. Select the closest measurement from the ring size chart to find your size.

Additional Ring Size Tips

1. Measure the interior of another ring that fits you using a tape measure and our printable sizer.
2. The ring should fit comfortably: tight enough not to fall off, but loose enough to slide over your knuckle with relative ease.
3. When the finger has a larger knuckle than the base, measure both points and choose a size between the two.
4. Measure your ring size at the end of the day when your fingers are warm. Finger size changes throughout the day and with the weather, and your fingers are actually smaller early in the morning and in cold weather. Also, keep in mind that fingers on your dominant hand are usually larger.
5. Measure 3 to 4 times for greater accuracy.
