If you're on Linux, install screenruler from your distribution's 
repositories (eg using sudo apt install screenruler)

On Windows, a similar utility is at 
https://sourceforge.net/projects/screenruler/

I'm sure there is an equivalent for Macs too (screensruler is written in 
Ruby, so it might work).

It sounds like you're doing all the right things. I'm sorry it's so tedious.
