How to Measure Ring Size at Home with Measuring Tape

Determining the correct ring size is crucial for a comfortable and secure fit. Whether you’re buying a ring for yourself or a loved one, knowing how to accurately measure finger size at home can save you the hassle of incorrect purchases. Here’s a step-by-step guide on how to measure ring size with a measuring tape:

Materials You’ll Need:

  • Measuring tape (preferably a flexible one for accuracy)
  • Ruler or measuring stick (optional)


  1. Measure the circumference of the finger: Wrap the measuring tape snugly around the base of your finger where you plan to wear the ring. Ensure the tape is not too tight or too loose. Take the measurement in millimeters.

  2. Convert circumference to diameter: To obtain the diameter of the finger, divide the circumference by π (pi), which is approximately 3.14. For instance, if your finger circumference is 56mm, the diameter would be 56 ÷ 3.14 = 17.84mm.

  3. Compare diameter to ring size chart: Refer to a ring size chart like the one provided below to determine the corresponding ring size based on the diameter measurement.

  • The average ring size for men ranges from 9 to 11.
  • Ring sizes can vary slightly depending on the ring style and width.
  • It’s important to keep in mind that the circumference of the finger may fluctuate due to factors such as weight gain, pregnancy, or temperature changes.
  • If you’re unsure about the ring size, it’s best to consult with a jeweler for professional guidance.
