How Many Feet Is a Block?

The size of a city block can vary depending on the location and city planning. In Manhattan, New York, a standard block is approximately 264 feet (80 meters) in the north-south direction and 900 feet (274 meters) in the east-west direction.

In Chicago, a typical city block measures 660 feet (201 meters) by 330 feet (100 meters), with 16 east-west blocks or 8 north-south blocks equaling one mile.These measurements are not universal, as block sizes can differ significantly between cities and countries. Factors such as urban planning, geography, and historical development can all influence the size of a city block.

The standard block in Manhattan is about 264 by 900 feet. In Chicago, a typical city block is 660 by 330 feet, meaning that 16 east-west blocks or 8 north-south blocks measure one mile, which has been adopted by other US cities.

How Many Feet Is A City Block??

Whether you're walking, driving, or looking at a map, you'll encounter the term “block” used to measure distances in cities. But how long is a standard city block? Here is a detailed look at block lengths in major US cities.

What exactly is a city block?

A city block refers to the distance between street intersections in an urban grid system. Blocks are the fundamental units that make up neighborhood patterns. Knowing block lengths helps estimate travel times and distances on city maps.

Blocks are defined by the roads surrounding them. For example, the stretch of buildings between Main St and 2nd Ave along Route 66 would be considered a block. Urban blocks provide the shape and structure to city design.

How are city blocks measured?

City blocks are measured by their linear length on each side. For example, a block might be 330 feet long by 660 feet wide. The dimensions depend on the city's layout and planning.

Block length also represents the distance between intersecting roads. If one block is 330 feet, then the next intersection will be another 330 feet down. Standard block measurements help navigation.

What is the typical length of a city block?

There is no universal block length, but some common standards have emerged:

  • New York City blocks – 264 feet long
  • Chicago blocks – 330 feet long
  • Standard US blocks – 300-400 feet long

Many major cities base their blocks on 300-400 feet lengths. This equals about 1/10th of a mile. But New York's long rectangular blocks and Chicago's square blocks stand out.

How long are New York City blocks?

In most of Manhattan, blocks measure 264 feet in length and 900 feet wide. This pattern comes from the 1811 Commissioners' Plan which established New York's grid system.

The long rectangular shape of New York blocks allows more buildings per block. The 900-foot widths also create more north-southtraffic flow. Twenty blocks equal around one mile in Manhattan.

What are the dimensions of a Chicago city block?

Chicago standardized its blocks at 330 feet by 660 feet. The east-west axis faces the Chicago River, with buildings backing onto 330-foot alleys.

With 8 blocks north-south and 16 blocks east-west equaling a mile, Chicago's grid system creates consistent navigation. The city expanded using this block measurement model.

How long is a block in Los Angeles?

Los Angeles follows the typical US standard of around 330 feet per short side of the block. LA blocks measure 750 feet long by 330 feet across.

This shapes the more sprawling, interconnected neighborhoods of LA versus the rigid grids of Chicago or New York. But the 330 feet length persists as in many US cities.

Why are many US blocks around 330 feet?

There are a few reasons 330 feet emerged as a standard American block length:

  • At 1/10th of a mile, it creates readable grids with mile-long intersections.
  • The dimension fits with 36-foot wide road lanes to create logical networks.
  • A 330-foot walk takes 1-2 minutes for most people, a good block-to-block pace.
  • The size can accommodate various building footprints, parking, and fire access.

The 330 feet length simply works well for urban planning and navigation compared to much longer or shorter blocks.

How are block measurements used in navigation?

Block distances help citizens and city services estimate travel times. For example, walking 5 blocks should take 5-10 minutes. Police or fire vehicles can anticipate how long a 6-block response might take.

Blocks also indicate distance on maps and street signs as useful visual units. Just like using inches on a ruler, blocks geography provides a scaled reference.

How many feet are in a mile of city blocks?

With most US block patterns, 10 blocks equate to approximately 1 mile.

So one mile would contain 3,300 feet of blocks end-to-end.

At 5,280 feet per geographical mile, the 3,300 feet balances navigability with efficiency in city design. Mile-long major roads serve as handy mental benchmarks.

What are some ways to visualize how far a city block is?

Some ways to conceptualize a typical 300-400 foot long city block include:

  • About 1.5-2x the length of a soccer/football field
  • The height of a 30-40 story skyscraper
  • The entire facade of a large shopping mall building
  • 7-8 parked Hummers end to end
  • 12 typical American house lengths

Picture some familiar distance references – a football field, a massive tower, rows of houses. A block matches that scale.

How does block size impact urban life?

Block dimensions directly shape city neighborhoods and transportation. New York's long blocks allow prolific high-rises. Chicago's square blocks create corridor-like alleyways.

Small blocks make navigation easy but limit development plots. Large blocks can isolate neighborhoods but encourage retail continuity. Modern planners balance density, access, and character using block measurements.

What are some ways blocks get divided?

While main city blocks follow hundreds of feet patterns, they often get divided into smaller sections:

  • Half-blocks – Around 155 feet, splitting blocks in two
  • Quarter blocks – 80 feet, creating four block sections
  • Urban mini-blocks – 60 feet or less, improving walkability

Developers may also break blocks into uneven pieces as needed. But “block unit” terminology persists for urban divisions.

Do block lengths change as cities expand?

As cities grow outward, blocks may shift in scale but often retain proportional shapes. A 1700s town may have used 200 foot blocks which expanded to 330 feet in modern neighborhoods. Radial or angled streets also change block direction.

However, urban grids tend to maintain block logic. Suburbs fused onto old city grids may warp block dimensions. But the navigation aid of logical blocks continues in expanding metros.

How can I measure blocks in my city?

To measure your local blocks:

  • Walk the block with a fitness tracker to gauge the distance traveled.
  • Note the block's start and end points and use online map tools to calculate the length.
  • Refer to your city's planning maps and documentation for specified block dimensions.
  • Ask your local transportation or planning department for the official block measurement standards.
  • Count steps heel-to-toe and multiply by your stride length to estimate block distance.

Checking your city's conventions for blocks can make navigating and understanding maps much easier. Just remember the typical dimensions fall around 300-400 feet per side in US cities.

What are some key takeaways on block sizes?

  • Standard US blocks range from 300-400 feet on each side
  • New York blocks are uniquely long at 264 feet
  • Chicago's grid uses 330 by 660 blocks as a mile benchmark
  • Blocks provide useful navigation and planning tools for cities
  • Block measurements dictate neighborhood design and transportation
  • Divided blocks, half-blocks, mini-blocks, and more provide versatility

Whether you're in Manhattan, Los Angeles, Houston, or another metro, city blocks gauge distances for urban life. Learning your city's block conventions provides perspective and context to enhance your navigation abilities.
