Ring Size Guide (International Conversion & How-to)
Getting the right size is essential. Below are three easy measuring methods plus a handy US size chart (diameter & circumference) to help you find your perfect fit.
1) Three Measuring Methods
-
Paper/String Method (most common)
-
Wrap a thin strip around your finger and mark the overlap; 2) Measure the length with a ruler (circumference); 3) Match the value to the chart below.
Tip: Measure during your usual wear time (fingers are slightly larger in the evening).
-
Existing Ring Method
Measure the inner diameter of a ring that fits well (mm) and refer to the chart.
-
Printable Sizer (optional)
Use a printed ring sizer to compare or test by holes.
2) US Size Chart (Common 5–13)

Note: Circumference ≈ Diameter × π (3.1416). Values are commonly used references.
3) Picking the Best Fit
-
Prominent knuckle: choose a size that slides over the knuckle but doesn’t spin;
-
Wide bands: often half-size up feels better;
-
Temperature effect: fingers are tighter in summer, looser in winter—evening measurements are more realistic.
