How wide is Texas? How long is California? The table below gives the width and length of every US state in miles and kilometers. Width is the greatest east-west distance between a state's westernmost and easternmost points, and length is the greatest north-south distance between its southernmost and northernmost points, both measured as straight-line (great circle) distances computed from official US Census Bureau boundary files. Click any column heading to sort, and scroll down for a measurement map of each state. Note that other published figures sometimes use different definitions, such as the longest diagonal, so numbers can differ slightly between sources.
Every US State by Width and Length
Width is east-west, length is north-south. Distances include islands, which is why Hawaii and states with offshore islands measure larger than their main landmass alone.
| # | State | Width (mi) | Width (km) | Length (mi) | Length (km) |

Measurement Maps for Every State
One map per state showing its east-west width and north-south length. The District of Columbia (12 miles wide, 14 miles long) is not a state, so it has no map.
Data Sources and Notes
Dimensions were computed from the US Census Bureau cartographic boundary files (2024 edition). For each state, width is the great circle distance between its westernmost and easternmost boundary points and length is the great circle distance between its southernmost and northernmost boundary points, including islands. Because the boundary files are generalized for mapping, distances are accurate to within a few miles. This page is for general reference and educational purposes.
