Manhattan Island is approximately 13.11 miles long, though other estimates put it at 13.4 miles long. The 13.11-mile distance runs from The Henry Hudson Bridge in the north down to Battery Park in the south.

Manhattan is only 2.3 miles wide, notes NYC The Official Guide. The borough is not very big, considering that the population was approximately 1.6 million people in 2013, according to the Department of City Planning for the City of New York. That is equal to about 66,666 people per square mile. The borough is divided into avenues, mostly running north and south, and streets that mainly run east and west.
