tool to get the size of each packages?

["Tam, Vincent" <vincent@aib.net>]

Dear all,

Is there any tool(s) to get a report of each package's used size in the 
Debian 2.2 system? I know that the new console-apt can show the 
package's packed size and install size, but I cannot find such function in 
the dpkg. Anyone kind to tell me where can I get this info?

Thanks!! Pls reply a copy to my e-mail if possible!
