Display True file size using ls -l command in CentOS

I am trying to figure out the actual size of files and directories on a CentOS Linux 5 server and when I do a ls -l I see for example at the Directory of /Data 4096 but once in side the directory and I do a ls -l I see larger file sizes. How do I get the actual file size of a Directory to show up?
Thank you,

Use "du -sx /Data" .

The 4096 you are seeing is the size necessary to store the meta-data about files (including the file names contained in that directory), not the size of everything in the directory.

You want to know the size of the directory and it's content, so try
du -h dirname
which will show you the files, the size of the files (in "human" readable form) and the size of the directory.
du -sh dirname
will show you on the total size of the directory and
man du
will tell you about the du utility (and suggest See Also.

Hope this helps some.
