The most frequently asked question about online ring shopping is: “I don’t know my ring size, how can I find out?” The good news is — you can accurately learn your size at home in just a few minutes without going to a jeweler. Here are three reliable methods and a practical size chart.

1. Method: Measuring from an Existing Ring (Most Reliable)

If you already have a ring that fits your finger perfectly, measure the inner diameter (from inner edge to inner edge) in millimeters using a ruler. Find your size in the chart below.

2. Method: Measuring Finger Circumference with String or Tape

Wrap a thin string or paper strip around the knuckle of the finger you will wear the ring on. Mark the point where the string meets and measure the length with a ruler — this is your finger circumference. In Turkey, the commonly used ring size can be roughly found using the formula “circumference (mm) − 40” (e.g., 54 mm circumference ≈ size 14).

3. Method: Measurement at a Jeweler

For the most accurate result, you can visit a jeweler and have them measure with a sizing ring. Once you know your size, you can use it for all your online purchases.

Ring Size Chart

Inner Diameter (mm) Finger Circumference (mm) Size (TR)
15,9 50 10
16,5 52 12
17,2 54 14
17,8 56 16
18,5 58 18
19,1 60 20

Note: Sizes may vary slightly from brand to brand; if you're unsure, choose the larger one.

Tips for Accurate Measurement

  • Fingers swell throughout the day — take the measurement in the evening. Measuring in cold weather can be misleading; measure when your hands are at normal temperature.
  • If your knuckles are wide, choose a size that can pass over the knuckle.
  • For wide band models, prefer half to one size larger.
  • Once you know your size, the fun part is next:
