One on top of the other

Both outlines on one axis, at the same scale. Sizes come from the makers’ published girths; where a usable cut-out exists, the profile itself is traced from it. Where they overlap they’re the same; the gap is the difference.

Side by side at the same scale

Drawn to scale: sizes from published girths, and the profile traced from the cut-out where we have one. Point positions along the shaft are approximate.

How the numbers compare

Differences of about ¼ inch or more are highlighted. Blanks mean the maker doesn’t publish that point.

Which one should you get?

Every line generated from the spec deltas above.

Stepping up from the Small to the Medium adds 2.7″ of girth: 7.1″ around becomes 9.8″.
That’s over an inch in one step. Owners who’ve worked up sizes generally suggest half an inch to an inch of girth at a time, so this is a jump rather than a nudge — the one to be careful with if the Small already sits near your limit.
The Medium is the longer of the two: 5.9″ of usable length becomes 7.5″.
Between the two? There’s no rung between them in the sizes we track for this sculpt — so it’s the Small, or a different sculpt that lands in the gap.
