I've never heard of that for -Q.  I though 80, which is what I get, was
standard, at least under X, and that's what the Emacs user manual says
(info "(emacs) Window Size X"): "The default frame width is 80
characters and the default height is between 35 and 40 lines, depending
on the OS and the window manager."  What graphical display system are
you using?
