What it does mean, of course, is that for any given hardware and mix

The code itself may be bigger but, looking at the sizes of
applications in /bin on both a 32bit and 64bit system, and the
libraries in /lib abd /lib64, I wouldn't say the sizes are anything
more than about 10% bigger.
Use the "size" command, not the file size.
As for the data, why would it be "substantially" larger on a 64bit
system? Pointers are going to be bigger on the 64bit system, as are
variables of type "long", since these are 64bit, but those of type
"int", and smaller, still occupy the same sizes in both the 32bit and
It's "substantial" because every pointer and every int is twice as big
in a 64-bit programming model compared to a 32-bit one.
