Cl- (Chloride ion) is larger in size.
Why? Anions are bigger than the atoms from which they were formed because they have gained electron(s). In this case, it has gained one electron.
Cl- is larger than Na+ because Na+ is a cation. Cations are smaller than the atom from which they were formed because they have lost electron(s).

cl- is larger than cl because there is sideways repulsion between electrons on the same orbit and there is more repulsion with more electrons. Na+ is smaller than Cl- because the outer orbit is lost in ionization therefore its smaller
