How to control the default plot size?

I am having an annoyance problem with Mathematica 3.0.1 for PowerPC
under MacOS 8.1:

When recomputing any kind of plot, such as ListPlot[],
ListDensityPlot[], etc, the plot size won't stay as set, instead often
reverting to 2 by 3 inches or so on the screen, at random. In some
cases, the size shrunk to 0.5 by 0.5 inches. There doesn't seem to be
any pattern to when a plot will stay the size it was set to (by
dragging the lower right corner), and when it will revert to the
default small size.

I assume that there is a Front End default one can set, and I have seen
it mentioned in the Holy Tome, but I have been unable to actually find
it. Any suggestions?

Lets look at the Options Plot has.

In[1]:=
First/@Options[Plot]

Out[1]=
{AspectRatio,Axes,AxesLabel,AxesOrigin,AxesStyle,Background,ColorOutput,Comp
iled,DefaultColor,Epilog,Frame,FrameLabel,FrameStyle,FrameTicks,GridLines,Im
ageSize,MaxBend,PlotDivision,PlotLabel,PlotPoints,PlotRange,PlotRegion,PlotS
tyle,Prolog,RotateLabel,Ticks,DefaultFont,DisplayFunction,FormatType,TextSty
le}

The option you want is ImageSize. Suppose you want Plot to make a
graphic with a width of 425 (I think the units are printer points) and
height determined by the specified aspect ratio. The line below will
make that the default.

In[14]:=
SetOptions[Plot,ImageSize->{425,Automatic} ];

Hi Joe,
did you try to set

Options[#,ImageSize->{450,450/GoldenRatio}]&/@{Graphics,ListPlot,Plot}

or something like that?
Cheers,
Peter

Joe,
Image size can be set from the Option Inspector either at Notebook or
Global level by using the option ImageSize
