Richard, what you're saying is of course mathematically correct. :-) But it's also TOTALLY useless - and only further serves to spread the confusion that screen/web images "really have" a DPI. If people think that your ruler-idea is relevant, then they will start to creat screen/web graphics with 92 and 98 and 88 and 101 DPI - ALL OF WHICH IS SENSELESS AND A COMPLETE WASTE OF TIME.<HR></BLOCKQUOTE>

I'd just like to qualify that a bit. Totally useless is a bit extreme.

If someone wants to print out something so it's the same size on screen as on paper, then the procedure I described is useful.

This method is also one of the things that helped me understand the relationship between 'resolution', what I see on my screen and what I see on paper after I've printed my images.

Of course, as has been mentioned several times in this thread, anything to do with image resolution is useless in the context of images for the web.
