You have to stop thinking in terms of any number of pixels equalling an
inch, either on Mac or PC systems. DPI is a PRINT value, not a monitor
value. I just did what you say below. I made an image 96 pixels wide (I'm on
a PC) and measured it with my ruler. The result? An image approximately 3/4
inch wide.

Why? Because my 17" monitor's RESOLUTION is set to 1600 x 1200 pixels. If I
was on a 15" monitor set to the same resolution, the 96 pixel image would be
even smaller. If I was on my 17" monitor, but set my resolution down to 1024
x 768, the image would be larger. (I'll do it to prove it right now.)

Result? An image 1-3/16" wide.

Having said that, it still may be true that Mac's display LESS pixels per
unit value than do PCs. (I don't have a way to test that.) Which may mean
that my 96-pixel image may appear larger on a Mac vs. a PC with both
computers using the same size monitor set at the same resolution.

  I am not kidding.  
  Make square image 72px width and height.
  View it on your Mac.
  Get a ruler and measure the square on the screen.
  If it has an inch  vertically and horizontally
  then the resolution of your screen is 72 dpi.
  DPI  means  dot per inch -  you can translate it
  to  pixels per inch.
  And BTW  Mac was probably the first WYSIWYG system
  which meant:  what (size) you see on the screen
  should be exactly the same (size and shape) on printout.

  Windows on PC is not (in this respect) WYSIWYG system.
