You have only changed the pixel height of the font, without changing
the height in points, or the width of the font. This makes Emacs try
to accomodate your request as far as it can, so even though the
closest matching font is wider, it uses the width you specified (80 in
tenths of points) in frame width calculations. If you replace the
other size specifiers with wildcards, the frame width changes as
expected:

(set-frame-font
 "-outline-Lucida Console-normal-r-normal-normal-18-*-96-96-c-*-iso8859-1")
