So it seems waht is inconsisitent is the underlying xft (or freetype)
libraries.

Can you explain the "despite the comment"? The comment doesn't claim pango
uses double-width characters. (assuming you mean characters when you say
fonts, as only one font is involved).
The problem is that when you ask freetype for a width, you sometimes get
the width of a double-wide character as base width, and sometimes that of
a single-width character. This is why urxvt has to measure it.
It doesn't help that many gnome programs, xterm and some terminal apps use
their own hardcoded table of character widths instead of relying on the
user-configured locale, as urxvt (and again, others) do.
I don't think this makes for the difference, however. Most likely urxvt
uses the spacing, while gnome-terminal the glyph width (both of which have
advantages and disadvantages).

The letter spacing has nothing to do with font sizes. I would *expect*
gnome-terminal to use the equivalent of "size=", though, and wold be
surprised if it used it's own
In any case, your problem likely boils down to using a low-quality font that
is not suitable for charcell displays. Font quality plays a big role with
xft.
