The number of members in a State Legislative Assembly varies depending on the population and geographical size of the state, subject to minimum and maximum limits set by the Constitution (generally between 60 and 500, though some smaller states have fewer than 60 MLAs). The number of seats in the Legislative Assemblies of the given states are: Arunachal Pradesh (60), Himachal Pradesh (68), Manipur (60), and Meghalaya (60). Thus, Himachal Pradesh has the highest number of members among these four states.
