When checking file sizes there are two sizes "size" and "size on disk" please can someone explain what the difference is between these two. Thanks!

You will have to be a bit more specific that that?

Where are you checking these sizes?

A disk is divided in blocks (called Sectors i think)

Lets just says a Sector is 4 kb and your file is 6 kb. The file size is 6 kb but the space on disk will be 8 kb. This is because you can only have one file occupying a sector and if a file uses even one kb of a sector the next file must start in a new sector.

So theoretically the file is occupying 2 sectors (not one and a bit) and is said to occupy 8 kb on this disk instead of the 6 kb true size of the file.
