The Dimensions of City Blocks

Tumblr_n4vk2vtTjD1s3dn7vo1_1280

From Seth Kadish's VizualStatistix:

A block is by no means a standard unit of measurement.

Depending on the urban plan, blocks can be square or oblong, and can vary significantly in side length.

For this plot, I measured the median length of downtown blocks in six cities that have regular grid layouts — that is, the dimensions of their city blocks are consistent.

I've included blocks per mile along the outer axes, and the ratio of short to long dimension for each city.

For this value, one represents a perfect square while smaller values indicate more oblong blocks.

Excellent work! Are these dimensions inclusive of street widths? Of sidewalks? Thanks.

Denver short side = 350 ft and 15 blocks/mile. 15 x 350 is 5250 ft, 30 ft short of a mile which means the 14 streets between the 15 blocks are each 2 ft wide.
