Average Ring Size for Women & Men
The honest averages, by finger — and why height and weight cannot predict your size, no matter what a viral chart claims.
Last updated: November 2026
The averages
| Who | Average ring finger size (US) | Typical range | In mm (circumference) |
|---|---|---|---|
| Women | 6 – 7 | 5 – 8 | 51.9 – 54.4 mm |
| Men | 9 – 10 | 8 – 11 | 59.5 – 62.1 mm |
These ranges match the sizes jewellers sell most. Use them only as a fallback for a surprise — see measuring secretly for better options, and the women's and men's charts for full detail.
By finger
The ring finger is the reference finger. As a rough guide on the same hand: the middle finger is usually about one size larger than the ring finger, the index finger similar to the middle, the pinky about two sizes smaller, and the thumb several sizes larger and hard to size without measuring. Always measure the exact finger the ring is for.
Myth-busting: height, weight and shoe size
There is no reliable formula linking height, weight, BMI or shoe size to ring size. Finger size depends on bone structure, knuckle width and soft tissue — which vary independently. Any site that “calculates” your ring size from your weight is guessing. The only honest shortcuts are measuring (how to measure) or using the on-screen sizer with a ring you own.
