directory size with ls -l

am I right in assuming that in unix a directory size is just information about that directory stored somewhere on the file system, and not a sum of its contents? This is because ls -l gives 1024 as my directory size, when the directory contains many gigs worth of stuff.

also, is

du -sk dir

the best way to see the total size of the stuff the directory contains?

ls -l on a directory gives the size of the directory file - the place where file metadata lives.

without resorting C code try:
du . | awk '{sum+=$1} END {printf("%12.0f\n", sum*512)}'

The . is the current working directory, this gives usage from there on down.
