However, as reference points for US cities, the standard square blocks of Portland, Houston, and Sacramento are 264 by 264 feet (80 m × 80 m), 330 by 330 feet (100 m × 100 m), and 410 by 410 feet (120 m × 120 m) respectively (to the street center line). Oblong blocks range considerably in width and length. The standard block in Manhattan is about 264 by 900 feet (80 m × 274 m); and in some U.S. cities standard blocks are as wide as 660 feet (200 m).

I’ll admit it’s a bad unit of measurement given that Baltimore has weirdly shaped and non-standardized blocks. Looking at my Lime history, my rides seem to fall in the 0.5-2.5 mile range (0.8-4 km)

It's different in every city, but in Baltimore they're probably in between the size of Portland, OR city blocks and New York City, NY city blocks https://www.youtube.com/watch?v=lisZBL3_aW8
