Women’s ring size guide
A gender label cannot predict an individual ring size. Measure the intended finger and hand, then consider the setting, band width and whether the ring can be resized.
Your size is US 6 (UK L½, EU 52).
Measurement check Exact table match
Measurement check Standard chart conversion; final fit still depends on band width and knuckle shape. Confirm with a printable or physical sizer before ordering an expensive ring.

Why this size?
Your input maps to US 6 — UK L½, EU 52, JP 12, Ø 16.51 mm.
Calculated dimensions are rounded chart values, not a measured accuracy guarantee. Ruler placement, print scale, screen calibration and the finger can change the result. Confirm with a physical sizer before ordering.

Measure the intended finger
- Measure the exact finger and hand where the ring will be worn.
- Repeat the measurement at a normal room temperature.
- Check the knuckle as well as the finger base.
- Convert the measured diameter or circumference, not a guessed demographic size.
Plan the purchase and fit
For a surprise, borrow a ring worn on the same finger and choose a design that can be resized. Stacks and wide bands can feel different from a single narrow ring, so confirm with a similar-width sample before buying an expensive or non-resizable style.

How can I size a surprise engagement ring?
Measure a known-fitting ring from the same finger and hand, choose a resizable setting, and confirm with a jeweler when possible.
