Maybe
  set size canvas ...

Question: "fig" can be metric or inches, how it will be rescaling?

You mean to issue this message if "set size != 1,1" when parsing commands
"set term ..." or "set out ..."?

There is yet another need for "size > 1": 3D splot drawings are sometimes
too small (only "set lmargin" works) and a bit larger plot is more optimal
for screen terminals.
