Tips to make sure you find the correct size.

  • Your fingers change size over the course of the day. Keep in mind if you're very warm, your fingers will be bigger and if you're cold they'll be smaller. Measuring when you're a bit warm will ensure that the ring will fit all the time.

  • Keep in mind, your dominant hand will almost always be slightly bigger. Make sure to measure each finger individually.

  • When using a string or paper to measure your finger, don't let it get loose but don't pull it tight. Doing either will skew the size of your ring.

  • For best results, measure 3 or 4 times and compare results. You want to make sure the sizing is accurate.
