Erroneous ImageSize?

I'm Showing a couple of different GraphicsArrays of plots and trying to
magnify their size, on screen and especially on printout, using

   Show[GraphicsArray[{---}], ImageSize->{432,180}]

Increasing the numerical parameters in the ImageSize option definitely
increases the size of the figures; but 432 points -- which should be 6
inches, right? -- only gives me a *5 inch* wide plot, both on the
screen and on the paper.

That is, on screen, with Ruler and Show Page Breaks turned ON, if I
click on one of the figures the bounding box for the plot is only 5
inches wide, according to the Ruler.  

And on the paper the actual printed figures are also smaller than 5"
wide by about the amount of margin between the bounding box and the
actual plots.

Using just ImageSize->432 gives me a square bounding box, 5" both ways;
but since the GraphicsArrays have an overall aspect ratio more like
1/3, the 180 vertical should give plenty of margin around them, top and

I don't knowingly have any magnifications or demagnifications turned on,
for the screen display or in the Page Setup or Print dialog boxes; they
all say 100%.  All the Magnification parameters in the Option Inspector
for the Notebook are set to 1.
