Actually, you're supposed to use "Size" rather than "Size on disk". The on disk number shows you how many bytes the file uses, rounded up to the full cluster size, which depends on your filesystem.

A file that's 32770 bytes will show as 65536 bytes on disk with a 32KB cluster size, but only 33280 bytes on disk with a 512 byte cluster size.

If you are using NTFS compression or sparse files, then the "on disk" number will show you the size of the compressed/sparse file, complicating matters further.
