How many city blocks are in one mile? – Each city has a different ratio of city blocks to miles. Because there is no standard length for a city block in the United States, the length of blocks varies across the country.
To calculate the number of blocks in a mile, it is necessary to know the average size of a city block. Urban planners recommend that pedestrian-friendly blocks range in length from 300 to 600 feet. A mile is 5,280 feet in length. Using the median of 450 feet from the recommended range of 300 to 600 feet, a mile would consist of 11.73 blocks.
However, block lengths vary considerably. In New York, the average length of a city block is approximately 750 feet, whereas in Philadelphia and Portland, Oregon, the average length is 400 to 500 feet and 200 feet, respectively.
In New York, a mile can be reached in approximately seven blocks. However, not all city blocks are square, so walking direction must be considered. If the block in question has a width comparable to that of a rectangular block, the calculation must be adjusted accordingly.
