What determines the physical size of a pasted bitmap?

[IanW]

When a bitmap on the clipboard is pasted to a (truly) blank powerpoint slide,
what determines the physical size of it, relative to the size of the slide?

I am often pasting a graphic of a fixed number of pixels wide and high, but
on different computers, the pasted graphic appears smaller or larger (~25%)
relative to the slide. Manually re-sizing it can lead to inconsistency
and/or is tedious.

The two PCs have the same, normal 96 dpi display settings, but different
screen resolutions. Both use PowerPoint 2002.

Thanks in advance for any help.

Have you tried setting the PCs to the same resolution to see if that eliminates
the problem?

Unfortunately the two computers (laptops) have very different native screen
resolutions (1400x1050 & 1024x640(?) ). Next time I have access to the latter
I'll try using an external monitor on each to enable a common screen
resolution.

Meanwhile, I did run one PC at both 1280x1024 and 1280x768, and the graphics
pasted to the same size on the PPT slide. So there is a difference between
the PCs...

I the issue is how the slide size (i.e the boundaries of the white "paper"
in the Normal view) defined? A dimension in inches, coupled with a DPI value?
Or just a set number of pixels horizontally and vertically?

This must be related to the "File>Page Setup>Slides sized for:" setting, but
the Help does not give much info on this setting, especially the on-screen
setting. My next step is to test that setting on both PCs......

Thank you Steve -- good answer, and lots for me to pursue!
