Ring Size Guide

Finding the perfect ring size is crucial for comfort and style. Use the guide below to determine your ring size at home. We recommend the following methods:

  • Method 1: Measure an Existing Ring (Diameter Method)

    Select a Ring that Fits the Desired Finger

    Choose a ring that fits comfortably on the finger you intend to wear the new ring on.

    Measure the Inside Diameter

    Use a ruler or a caliper to measure the inside diameter of the ring (from edge to edge across the center). Ensure the measurement is in millimetres (mm).

    Match the inside diameter to the corresponding South African and US ring sizes.

  • Method 2: Measure Your Finger (Circumference Method)

    Wrap a String or Paper Around Your Finger

    Take a thin strip of paper or a piece of string and wrap it around the base of your finger.

    Ensure it’s snug but not too tight.

    Mark the Spot

    Use a pen to mark where the paper or string overlaps.

    Measure the Length

    Unwrap the paper or string and measure its length in millimetres (mm) with a ruler.

Tips for Accurate Sizing

  • Measure your finger at the end of the day when it’s warm, as fingers can change size throughout the day.
  • If you’re unsure between two sizes, it’s usually safer to choose the larger size.
  • Remember, wider rings may feel tighter, so consider going a half size up for wide bands.
