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.

Whoah! +1 screenruler! this is awesome! This is a very necessary tool for desktop-customization and obsessive UI tweakers, like ms gamerchick. ;D – emf Oct 08 '10 at 17:11

I 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. – emf Oct 08 '10 at 17:12
Glad to help out. :) I hope it helped the OP. – gamerchick02 Oct 08 '10 at 19:23
I installed screen ruler and for some reason it does not work. It is simply not visible, there is only the icon on the Unity launch bar. Does anyone know why? I have Ubuntu 12.04 – d.k Apr 28 '13 at 21:35

Both do not allow an arbitrary ruler angle. – Adobe Mar 10 '15 at 17:22
Both links are dead now. – Ruslan Nov 15 '18 at 09:47
Sadly, 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 ? – matthieu Sep 11 '19 at 15:11
Screenruler is a fantastic and fully-functional program, even now. – Ross Dec 25 '19 at 01:33
The second link is DOA. – WinEunuuchs2Unix Jun 08 '20 at 02:13

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.

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.
