I suspect it's actually the sum of the sizes of all the files in the
package rather than the space that would be taken on the disk, since
that would depend on the filesystems in use. It should be easy enough to
verify by looking at a small package:
$ rpm -q --queryformat 'Size of installed %{NAME}-%{VERSION}-%{RELEASE}
package is %{SIZE}\n' fedora-release
Size of installed fedora-release-2-4 package is 272656
$ rpm -qlv fedora-release

$ rpm -qlv fedora-release | awk '{ size += $5 } END { print size }'
272670
The difference in size here (272656 vs. 272670) could be accounted for
by the 14 bytes used by the symlink /etc/redhat-release ->
fedora-release, which perhaps the RPM "SIZE" field doesn't include?
So if you wanted to calculate the actual space taken on disk, you'd need
to round up the size of each file in the package to the next multiple of
the block size for the filesystem that file would be installed on. This
could be made more complicated by the fact that some filesystems (e.g. I
think ReiserFS) may have variable block sizes to handle lots of small
files efficiently.
