Well here is a randomly picked example:

-rwxr-xr-x 1 root root 85536 Jan 30 2007 /data/.chroot/debian-pure64/bin/ls
rceng02:~# ls -l /bin/ls
-rwxr-xr-x 1 root root 77352 Jan 30 2007 /bin/ls
So /bin/ls appears to be 10% larger.
On my Fedora 7 systems, /bin/ls is 5% larger on 32-bit than 64-bit:
[mfk8@dhc015066 ~]$ ls -l /bin/ls ; file /bin/ls
-rwxr-xr-x 1 root root 99468 2007-06-13 10:06 /bin/ls
/bin/ls: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV),
dynamically linked (uses shared libs), for GNU/Linux 2.6.9, stripped
[mfk8@dhc015066 ~]$
[mfk8@wayga ~]$ ls -l /bin/ls ; file /bin/ls
-rwxr-xr-x 1 root root 95056 2007-06-13 10:31 /bin/ls

rceng02:~# ls -l /bin/gzip
-rwxr-xr-x 4 root root 52672 Sep 19 2006 /bin/gzip
rceng02:~# ls -l /data/.chroot/debian-pure64/bin/gzip
-rwxr-xr-x 4 root root 60216 Sep 19 2006
/data/.chroot/debian-pure64/bin/gzip
So /bin/gzip appears to be 14% larger. I seem to recall gzip also runs
quite a bit faster on 64bit.
gzip is about 5% larger on 64-bit (67120 bytes) than 32-bit (64116 bytes).
Go figure.
