And where can I find their intended dimensions?

As near as I can tell, a "regular" banana plug fits a 0.15 inch jack.

What might be a "miniature" banana plug fits a 0.12 inch jack.

What might be a "subminiature" banana plug fits an 0.10 inch jack.
Such as on the Triplett 310 multimeter.

And there are apparently "oversize" banana plugs that fit an 0.25 inch hole.

Can anyone verify the proper names and exact sizes?

I have a few in inventory and would have to resort to measuring them,
but that probably wouldn't help you very much.(?)

I can tell you this: For dual plugs, there are definitely different
hole spacings.
The "familiar" Pamona-type dual plug has about 1" space post-to-post,
but there's another size that's about 150% that spacing. I suspect
this could be for a higher current banana plug (as they so seem to be
"beefier"), but I can't swear to it.

ITT-Pamona (or some spelling like that), might be a good place to
Google for the datasheets, and hence size info. I think Tyco also
makes them these days.., and probably a hundred Chinese outfits whose
names I can't pronounce, let alone spell.

EF Johnson also used to make these back in the 80's.
Not sure if they still do, but might also be worth Googleing.

You are full of it.
The (standard) Pomona banana pair spacing is 0.75 inches, *NOT* one inch!!
This 3/4 spacing is seen on many DVMs and curve tracers (includes scope plugins).

Use DigiKey, and get the data*** for the Pomona 1269; *NO* dimensions are one inch!
