How to Measure Your Finger to Find the Ring Size

What You Will Need:

  • A piece of string or thin tape

  • A ruler

  • A pen

  • A ring size chart

Step by Step Guide

Step 1: Prepare the String

Take a piece of string (or thin tape) about 10 cm long.

Step 2: Wrap Around Your Finger

Wrap the string around the finger where you want to wear the ring. Do not tighten too much! It should be comfortable, just like a ring would be.

Step 3: Mark the Meeting Point

Use a pen to mark the exact point where the string overlaps.

Step 4: Measure the Length

Stretch the string along a ruler and check how many millimeters (mm) it measures up to the marked point.

Step 5: Compare with the Ring Size Chart

Now, compare the number obtained with the ring size chart below:

Important Tips

  • Measure your finger at the end of the day when it is slightly swollen to ensure a comfortable fit.

  • If your measurement falls between two sizes, choose the larger one for a more comfortable fit.
