The Owner's point here is that our friend Free Ruler can be moved around the page.
Quite different from having fixed rulers, top and side.

Clever little Nisus Man!!

Oh dear! you are so stupid, the little Nisus man said, - why don't you just move my friend Free Ruler around to the buttom stroke of the underline characters and then look at the measurements to see how much is left down to the buttom margen? - ...Well, the owner said, - can I be certain that these measurings are correctly? - Indeed you can, said the little Nisus man. You know what - My friend Free Ruler is so smart that he can make himself align to the size and percentual setup of even a big, big monitor - or a small one, if you could use that.

And if you didn't know, I'm also dynamic on a monitor, so the larger monitor, the larger page you will get, and my friend Free Ruler also grows with me, so we grow together.
