How To Measure Ring Size With String, Paper & Ruler

To measure ring size at home, follow these simple steps. If you need someone else's ring size, you can ask them directly or get help from friends and family for a surprise. You can also measure their existing rings using our ring size chart.

Steps to Measure Your Ring Size:

  1. Wrap a piece of string or paper around the base of your finger.
  2. Mark the point where the ends meet with a pen.
  3. Measure the length of the string or paper with a ruler (in mm).
  4. Divide the length by 3.14 (Pi) to find the ring diameter.
  5. Match the diameter to a ring size chart to find your size.

Tips to Measure Your Ring Size

When measuring your ring size, keep the following tips in mind:

  • Avoid measuring your fingers when they are cold, as they tend to be smaller.
  • Avoid measuring your fingers on very hot summer days, as they may be swollen.
  • If you have large knuckles, it's recommended to choose a slightly larger size to ensure a comfortable fit.
  • Measure your fingers at the end of the day, as they are likely to be the largest at that time.
  • Note that the ring size may vary between each hand, so measure the specific finger on which you plan to wear the ring.
  • For rings with stones, it is important to measure the size as accurately as possible to ensure the ring fits properly and doesn't spin around.

Advice for Buying a Ring as a Gift

Buying a ring as a gift can be a challenge when you are unsure of the correct ring size. Here are some suggestions:

    • Ask your partner, friends, or family of the person if they know the ring size.
    • Borrow one of the person's rings (on the correct finger) and measure it using the methods described above.
    • Consider choosing a ring that is adjustable in size to accommodate variations.
