I am trying to create a standard Excel chart size so that I can copy the
charts into Powerpoint. I have tried to put each chart on its own chart
sheet. However, it seems that the size of the chart varies depending on
which computer is used. Is there a way to create a custom sized chart sheet?
Is there another way to create a standard sized graph in Excel that can be
copied into Powerpoint? I would prefer to use chart sheets since they seem
support linked Excel charts better.

Any suggestions would be appreciated.
