**The standard distance of one city block is typically 311 feet long.** The length varies based on the city and the specific street.

Engineers typically use the estimate that one city block is equal to 100,000 square feet. It is estimated that there are 16 or 17 city blocks in one mile. While these are standard estimates, the true number varies based on the city.

In New York City, for example, one block between the avenues is typically the size of three city blocks. Some can measure as long as 920 feet, while the average length is about 750 feet. The best way to measure the true length of a city block is to walk it and measure your pace.
