How long is Long Island, N.Y. (from New York Harbor to Montauk point)?

Long Island is an island located just off the northeast coast of the United States and a region within the U.S. state of New York. Stretching east-northeast from New York Harbor into the Atlantic Ocean, the island comprises four counties: Kings and Queens (these form the New York City boroughs of Brooklyn and Queens, respectively) to the west; then Nassau and Suffolk to the east. However, many people in the New York metropolitan area (even those living in Queens and Brooklyn) colloquially use the term "Long Island" (or "The Island") exclusively to refer to the Nassau-Suffolk county area collectively, which is mainly suburban in character.North of the island is Long Island Sound, across from which lie the states of Connecticut and a small part of Rhode Island.

Both the longest and the largest island in the contiguous United States, Long Island extends 118 miles (190 km) eastward from New York Harbor to Montauk Point, with a maximum north-to-south distance of 23 miles (37 km) between Long Island Sound and the Atlantic coast. With a land area of 1,401 square miles (3,629 km2), Long Island is the 11th-largest island in the United States and the 148th-largest island in the world — larger than the 1,214 square miles (3,140 km2) of the smallest state, Rhode Island.
