If you don't have Synaptic Package Manager install it by typing the following commands in the terminal:
sudo apt-get install synaptic
(But first make sure you have allowed the Universe repository. Here's a link for the how-to: How do I enable the “Universe” repository?)
Next, start Synaptic Package Manager (reload the repos if necessary) and click on the Status tab, then click Installed,

From Settings menu, select Preferences,

Click Column and Fonts tab, scroll to find Installed Size and mark it, then click OK,

Now the Size column should appear in the Synaptic window. Click on Size to select sort column by size and toggle for ascending/descending order of arrangement.

You can then select the packages you want to remove and apply the action from this application itself.
