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.

S5 Blunt Plug≈4.1″ usable · widest shaft point 6.5″

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.

Total length	4.5″	5.0″
Widest girth	5.9″	6.5″
Narrowest girth	4.5″	5.2″

Which one should you get?

Every line generated from the spec deltas above.

Stepping up from the S4 to the S5 adds 0.6″ of girth: 5.9″ around becomes 6.5″.
That sits at the top of the half-inch-to-an-inch-per-step increment people usually recommend — a real step up, not a nudge.
The S5 is the longer of the two: about 3.7″ of usable length becomes 4.1″. Approximate — this maker publishes a total height rather than an insertable length.
Both sizes come in the same firmness options (soft–medium), so feel isn’t a variable here — only size is.
Between the two? There’s no rung between them in the sizes we track for this sculpt — so it’s the S4, or a different sculpt that lands in the gap.
