I'm certainly no expert in the technicalities, but it would seem to me 
that "pixel size" only makes sense when talking about physical media - 
i.e. if you know the size of a camera sensor or a computer monitor and 
you know it's dimensions in pixels, then you can easily calculate the 
size of a pixel.
