I usually have ring size 52 and so far also fit each ring in the size optimal. Here I have ordered 53 biggest and the ring is relatively narrow. Although still fits and goes smoothly over your finger, but you get undressed him only by means of water or a small twinge. Here, then, might not necessarily rely on the size, but rather measure it and order by that criteria.
Still, I'm all around satisfactory the ring shines beautifully and the "O-ring" seems to sit quite reassuring and firm.
