Largest US States by Land Area

Alaska is by far the largest US state by land area at over 570,000 square miles, more than twice the size of Texas. Texas, California, Montana, and New Mexico round out the top five. Land area shapes everything from infrastructure costs to species diversity to economic specialization (agriculture, mining, and forestry tend to dominate large rural states). The Census Gazetteer's official ALAND_SQMI figures exclude inland water; the largest states by total area would shift slightly if water surface were included.

Methodology

Rankings are based on American Community Survey (ACS) 5-Year estimates from the US Census Bureau. All 50 states and the District of Columbia are included. The ACS surveys approximately 3.5 million households annually and provides detailed demographic, social, economic, and housing data. 5-Year estimates offer the most reliable data for state-level comparisons by averaging responses over a 60-month period. Percentages may not sum to 100% due to rounding.
