if you are talking about the anion &cation of the same element , then anion will be larger. in anion ,number of electrons is greater than the number of protons .hence effective nuclear charge decreases & overall attraction of nucleus for electrons also decreases . hence size of anion increases.

It'll depend wholly on the cation/anions in question.

I think anions are smaller. because they have more no of electrons. hence, the attraction between the protons in nucleus and the electrons increses, getting them more closer, reducing the size of the cation.
