If you type “free on screen ruler” into Google, you get at least 10 useful results back. If only it was like that back in late 2004 when I actually needed one! But it wasn’t, so I had to spend a weekend writing my own, using an early version of Sharp Develop which liked to freeze, crash, and explode a lot. Fun times.
But despite all the difficulties, I managed to finish it. And only 4 short years later it’s finally available to anyone desperate enough to be actually willing to use it, for free.
It’s called yaRuler (yet another ruler – yes, very original, I know) and it looks like this:
