Perhaps size detection should be based on the angle subtended at the eye? That's what we are basing other stuff on. I think the linear size is much less relevant (and meaningless in some cases). To do it well, you probably need to know "how much is subtended by the display" . You probably should not need to know "what is the pixel count in that range" as the equipment designer should have made it that 'normal' sizes like 10pt text are, in fact, readable.
