Missouri County Area & Size Rankings

Understanding Missouri’s county areas

The land-area range runs from St. Louis city at 61.7 mi² to Texas County at 1,177.3 mi². The largest has 19.1 times the land area of the smallest and accounts for 1.7% of the combined county land in Missouri. Compare with every state’s largest county.

The median county-equivalent land area is 592 mi², below the national median of 604.5 mi². The median describes the middle of the county size distribution; it does not describe how people or development are distributed. A state with a few very large counties can have a much smaller median than its largest entry suggests.

Where water changes the picture

Camden County has the most assigned water area, at 52.7 mi². Stone County has the highest water share, with water making up 9.2% of its total area. Water area and water percentage answer different questions: the first measures an amount, while the second measures the mix of land and water.

Across all 115 entries, water accounts for 1.4% of the combined total area. This is calculated from the summed land and water measurements, rather than averaging county percentages, which would give each small and large county equal weight.

Where people live

An estimated 6,270,541 people lived in Missouri on July 1, 2025 (+1.9% since 2020), or 1.8% of the national total in this dataset. St. Louis County is the most populous county equivalent, with 990,911 residents — 15.8% of the state. The largest by land, Texas County, has 25,994.

Across the state there are 91 people per square mile of land. County densities range from 4,507 in St. Louis city to 7.2 in Worth County; the median county equivalent has 31. Switch the map above to density to see where the state’s population concentrates.

Compare the largest and smallest county equivalents in Missouri to see land, water, and total area on the same scale.

These calculations use the 2026 Census county records listed below. County-equivalent boundaries vary between states; area alone does not measure population, density, or usable land. See coverage and calculation rules.
