Measuring your finger

How to measure my finger’s diameter?

1. Wherever you want the ring to be on your finger, wrap a strip of paper around it.
2. To discover your ideal fit, make sure the paper is stretched tightly around your finger. The tighter, the better.
3. Make a mark where the paper overlaps, then use a ruler to calculate the distance (in millimeters).
4. To get your ring size, use the table below.

Advice & Techniques

When your fingers are at their biggest, measure them at the end of the day.

Make sure your fingers are warm because the cold can cause them to shrink by up to half a size.

Last but not least, avoid measuring after eating appetizers and beverages because both alcohol and salt can cause swelling in your fingertips.
