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.

XS Egg Plug≈2.9″ usable · widest shaft point 4.1″
Small Egg Plug≈3.5″ usable · widest shaft point 4.8″

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.

	XS Egg Plug	Small Egg Plug
Total length	3.5″	4.2″
Widest girth	4.1″	4.8″
Firmness options	soft–medium	soft–medium
Knot	no	no

Which one should you get?

Every line generated from the spec deltas above.

Stepping up from the XS to the Small adds 0.7″ of girth: 4.1″ around becomes 4.8″.
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 Small is the longer of the two: about 2.9″ of usable length becomes 3.5″. 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 XS, or a different sculpt that lands in the gap.
