How to Measure Your Ring Size Easily at Home

You can use a small piece of paper to easily measure your ring size at home.

Steps

Cut a small and long strip of paper, then wrap it around your finger.
Wrap it around the widest part of the finger joint that you want to measure.

Use a pen to mark the point where the two ends of the paper overlap.

Measure the length from mark to mark.
This length is the inner circumference of the ring.

Notes

✔️ When wrapping the paper, make sure it fits snugly, not too loose.
✔️ Finger size may change depending on the time of day or physical condition (for example, when fingers are swollen).
