Method 2: The String or Paper Trick

If you don't have a ring, you can measure your finger directly:

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 string or paper against a ruler (in millimeters).
4. Subtract the outer thickness to get the internal diameter, or use our circumference guide.

3 Tips for the Most Accurate Results

• Measure Multiple Times: Your finger size can fluctuate throughout the day. Measure 3-4 times for consistency.
• Check Your Knuckle: If your knuckle is significantly larger than the base of your finger, measure both and choose a size in between.
• Consider Band Width: Wider bands feel tighter than thin ones. If you're buying a wide ring, consider going up half a size.
