ls -s lists the amount of storage space used by the file's content (excluding space used for metadata). This can differ from the file size in two ways: In most cases, the file size is rounded up to a whole number of blocks. The size of a block is typically 512B to 4kB but it depends on the filesystem (and some filesystems don't have this concept). If the ...

Consider for example, if you open new file, seek 1G into it, and write something, the OS doesn't allocate 1G (plus the space for something) on disk, it allocates only the same for something -- this is called a "sparse file".
