Puerto Rico has a total area of approximately 3,424 square miles (8,868 to 9,104 square kilometers), making it the third largest island in the United States and the 82nd largest island in the world. The island is roughly rectangular, measuring about 100 miles long by 35 miles wide (160 km by 56 km).
Puerto Rico is an archipelago consisting of the main island and 143 smaller islands, islets, and cays. It is the smallest and most eastern of the Greater Antilles in the Caribbean. In terms of comparison, Puerto Rico is about three times the size of Rhode Island in the U.S. The main island's maximum length is about 110 miles (180 km) from east to west, and the maximum width is about 40 miles (64 km) from north to south.
Thus, Puerto Rico is a relatively small island by global standards but significant in size compared to some U.S. states.
