I couldn't find the software thread, so I've put this in here.
I've been looking for a screen ruler that shows the measurements on the screen as accurate.
I've tried a few, and every one of them fails the test when I place my own ruler against the screen ruler. For instance - a measurement of 5 centimeters on the screen ruler shows as approx 4 cms on my real ruler.
