How do I measure the size of an area?
Solution 1
There are two packages in the repositories:
-
sudo apt-get install screenruler
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.
Solution 3
Well if you are going to use it for web design or web development then I would use the Web Developer extension within the FireFox Web browser. It also has tons of other useful tools which can be very helpful in your designs or development. It works great for CSS designs.
Take a look at it here https://addons.mozilla.org/en-US/firefox/addon/60/ . I also think they have it for Chrome. This will provide you with a great on screen ruler for all your design projects.

emf over 13 yearsI will comment something I just found: Screenruler is good, but does not show a number of pixels by default, just a hardly-visible tiny hashmarks. you have to right click and set "track mouse" to do this.

matthieu almost 5 yearsSadly, none of these applications let us measure things that are not either horizontal or vertical... I would love a tool that lets you click two points anywhere on the screen, and that tells you the distance between. Has anyone seen something like that ?
