Ring Size Guide

Determining Your Ring Size

There are several ways to determine your ring size:

Use a ring sizer tool by simply slipping the tool onto your finger. It will then tell you the size of your finger.

Measure the circumference of your finger using a tape measure or a piece of string.

Several factors can affect your ring size, such as temperature, time of day, and even hydration levels. Fingers tend to be smaller in the morning and larger in the evening, so it is best to measure your finger size later in the day when your fingers are at their largest. Additionally, extreme temperatures can cause your fingers to expand or contract, affecting the accuracy of your measurement.

Ring Sizing Tips

The average ring size in the United States is 6, but this can vary considerably based on the person’s build. To ensure an optimal fit, there are a few things you should consider when choosing a ring size:

  • Use an existing ring that fits correctly on the finger that you want to measure.
  • Be sure to account for the width of bands or stacking rings.
  • Rings should fit comfortably and be snug enough to stay on but loose enough to fit over your knuckle.
  • Remember that engagement and wedding bands are traditionally worn on the left-hand ring finger, while fashion rings can be worn on any finger on either hand.
