Quoting the manual:

     When the package passed to ‘guix size’ is available in the store,
  ‘guix size’ queries the daemon to determine its dependencies, and
  measures its size in the store, similar to ‘du -ms --apparent-size’
  (*note (coreutils)du invocation::).

     When the given package is _not_ in the store, ‘guix size’ reports
  information based on the available substitutes (*note Substitutes::).
  This makes it possible it to profile disk usage of store items that are
  not even on disk, only available remotely.

Maybe the package in question was neither in your store, nor on the
substitute server?

HTH,
