Size on disk is often different. The filesystem is broken down into small portions that I'll refer to as "chunks" to make it easy. The smallest level of chunk cannot be shared among different files. So if a file would only need 3.5 chunks it will be allocated 4 since 3 is not enough to hold it. Yes, the other .5 gets wasted, but gets counted in with the "size on disk" measurement.
