Measuring Ring Size: All Methods at a Glance

Measuring Ring Size: How to Do It Right

Measuring ring size is one of the most common jewelry pitfalls. Too tight = hurts. Too loose = falls off. With these methods, you can measure precisely – whether for yourself or secretly for a surprise.

Method 1: Measuring Tape or String Method

1. Place a thin strip of paper or string around your ring finger
2. Mark where it overlaps
3. Measure the length in millimeters
4. Circumference ÷ 3.14 = Diameter in mm
5. Convert to EU size (table below)

Method 2: Measuring an Existing Ring

Place a well-fitting ring (ring finger!) on white paper, measure the inner diameter with a ruler. Then look it up in the size chart.

EU Size Chart (Inner Diameter)

• 14.8 mm = Size 46
• 15.3 mm = Size 48
• 15.7 mm = Size 49
• 16.2 mm = Size 51
• 16.5 mm = Size 52
• 17.2 mm = Size 54
• 17.8 mm = Size 56
• 18.2 mm = Size 57
• 18.8 mm = Size 59
• 19.4 mm = Size 61

Important Notes When Measuring

• Always measure in the evening – fingers are up to one size smaller in the morning
• Dominant hand often has larger fingers
• Wide rings (6+ mm) fit more snugly – choose half a size larger
• If in doubt: buy larger and have it resized (easier than enlarging)
