Every buyable size on the shelf, ranked by the maker’s published circumference at its widest point, with owner-verified rows flagged. The top twenty are listed here, and every figure is the one shown on that size’s product page.

Girth at this end of the shelf is somewhere people arrive slowly, over years and in quarter-inch steps, and plenty of people never head this way at all. If any of these are new territory for you, the sizing-up page has the route.

Every entry below is genuinely purchasable today: in stock or poured to order, direct from the maker. Girth here is circumference, the tape-measure-around figure, which runs a little over three times the diameter.
