What is the width of the exclusive economic zone in International Law?

Article 57 of the United Nations Convention on the Law of the Sea, 1982 provides that the exclusive economic zone shall not extend beyond "200 nautical miles" from the baselines from which the breadth of the territorial sea is measured. Twelve nautical miles is the limit of the territorial sea (Article 3) and 24 nautical miles the limit of the contiguous zone (Article 33); 100 nautical miles is not the limit of any zone under the Convention.
