Mark the end where the paper meets and measure the distance with a ruler (mm).
Use the below chart to determine your ring size.

Tips & Tricks

Measure your fingers at the end of the day when they’re at their largest.
Cold weather can shrink your fingers up to half a size, so make sure they’re warm.
Lastly, alcohol and salt can make your fingers swell, so refrain from measuring them after cocktails and appetizers.
