How do I measure the size of an area? [duplicate]
Solution 1:
There are two packages in the repositories:
-
Screen ruler
sudo apt-get install screenruler -
kruler
I haven't tried either of them, but they might be what you're looking for.
Solution 2:
Screen Ruler, which can be found in your Ubuntu Software Center is great. But there is also another excellent tool that is available from installing Screenlets from the software center. Just type "ruler" in the search box after installing screenlets.
