Four ways
to measure
N°03
At Home
Use a physical ring sizer
01●●●●●

Use a physical ring sizer

The most reliable method. Slip it on and choose the size that's snug at the base yet clears the knuckle with slight resistance.

Measure a ring you own
02●●●●●

Measure a ring you own

Measure the inside diameter in millimeters with digital calipers, then set the dial above — or match it to the size table.

Print your own ring sizer
03●●●●

Print your own ring sizer

Print our one-page sheet at 100%, then use the true-size circles or the cut-out strip. Grab it in the section just below.

Measure your finger with string
04●●○○○

Wrap with string

A last resort. Wrap non-stretch string twice around the base, mark where it meets, measure in mm and divide by two for circumference.
