To calculate the exact size of the image, you must have knowledge of
ISO-9660 and mkisofs has this knowledge. So it looks logical to rely on
it rather than reinvent the wheel.
The image is by definition larger than the sum of the file size. You
have space lost for the filesystem meta-data and also because of the way
how data is stored (fixed-size blocks, ...).
