How to Read the New York Map Without Getting Lost

The 1811 Manhattan grid

In 1811, when the city barely occupied the south of the island, three commissioners approved a plan for what were still hills, farms, and swamps to the north. The Commissioners' Plan laid out a grid of avenues running north-to-south and streets crossing it east-to-west. They also decided to number them instead of giving them names, a practical and unromantic choice that turned the island into a large Cartesian plane.

The avenues run from First to Twelfth, counting from east to west. The streets start at 1st Street and go north up to 155th Street in the area covered by the plan. Thus, 42nd Street is south of 57th, and Third Avenue is east of Seventh.

Most cross streets were laid out at 60 feet wide, about 18 meters. Some, like 14th, 23rd, 34th, 42nd, 57th, 72nd, or 125th, were given 100 feet, about 30 meters, and today they remain the major commercial and traffic corridors crossing the island. If you exit the subway at 34th, you are on a wide street full of shops, and that stems from a decision made over two centuries ago.

There is a detail that confuses visitors with a compass. The grid does not point to true north because it follows the elongated shape of the island and is rotated about 29 degrees to the east. New Yorkers still call the direction of the avenues "north," and that conventional north is what subway maps and directions use.

The Fifth Avenue rule, East versus West

Fifth Avenue splits Manhattan into two halves for addressing purposes. Everything to the east of it carries the word East and everything to the west carries West. That is why 10 East 42nd Street and 10 West 42nd Street exist at the same time, two buildings on the same street on opposite sides of Fifth.

The building number also tells you something. On cross streets, numbering starts at Fifth Avenue and increases as you move away from it, both eastward and westward. A small number, like 10, indicates you are close to Fifth, while a high number, like 500, sends you several avenues further.

With those two clues you can decode an address in seconds. Imagine a friend invites you to meet them at 350 West 50th Street. The word West tells you to go west of Fifth Avenue, the 50th places you on 50th Street, and the 350 indicates that you are not right next to Fifth Avenue, but rather several blocks away, toward Eighth or Ninth Avenue. You just need to walk.

Addresses on the avenues themselves work differently. There, the building number does not match the nearest street, and to figure it out New Yorkers use an arithmetic trick that involves dividing the number by 20 and adding a different value depending on the avenue and section. In practice, almost everyone just asks "what streets is it between?", and advertisements usually answer in advance with formulas like "Fifth Avenue at 34th Street".

Broadway and the southern exceptions

The grid has a famous rebel. Broadway is much older than the 1811 plan, because it follows a path that already existed since colonial times, and it cuts diagonally across the island, intersecting the avenues. Every time it crosses one of them, it leaves a triangular or bow-shaped plaza, which is how Times Square—where Broadway intersects Seventh Avenue—and Herald Square—where it intersects Sixth Avenue—were born.

The south of the island completely escaped the plan. Lower Manhattan, the Wall Street neighborhood, preserves the layout of narrow, curved streets left by the Dutch and later the English, with proper names like Pearl, Beaver, or Maiden Lane instead of numbers. There, the rule of numbers does not apply, and the map reads like the historic center of any Latin American colonial city.

Greenwich Village is the most baffling case. The neighborhood already had its own streets when the grid arrived, and its residents resisted the new layout erasing them. As a result, some numbered streets twist as they enter the Village, and West 4th Street ends up intersecting West 10th Street, a corner that theoretically should not exist.

As a general rule, the grid governs north of 14th Street, roughly speaking. Below that line, you would do well to carry a map and some patience.

Uptown, Downtown, and Midtown

In Manhattan, nobody says \"I'm going north\" or \"I'm going south.\" They say they are going uptown or downtown. Uptown means heading north toward higher street numbers, bound for Harlem. Downtown means heading south toward lower numbers, bound for Wall Street. The logic stems from the grid itself, because going from 20th Street to 80th Street is literally going \"up\" on the map.

Words also name areas of the island. Downtown designates the south, from the Village to the tip. Midtown is the central strip, roughly between 34th and 59th streets, where the office skyscrapers, Times Square, and Grand Central Station are located. Uptown refers to everything north of Central Park, although it already feels like uptown in the Upper East Side and Upper West Side.

This vocabulary matters most in the subway. Many Manhattan stations have separate entrances depending on the train's direction, with signs reading "Uptown" or "Downtown," and if you enter through the wrong one, you cannot always cross to the other platform without exiting and paying again. Before going down the stairs, compare your destination with the street where you are. If you are going from 14th to 42nd, the number goes up, so you look for the Uptown entrance.
