Understanding Florida’s county areas

The land-area range runs from Union County at 243.9 mi² to Collier County at 1,997 mi². The largest has 8.2 times the land area of the smallest and accounts for 3.7% of the combined county land in Florida.

The median county-equivalent land area is 696.5 mi², above 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

Monroe County has the most assigned water area, at 4,306.5 mi². It also has the highest water share, with water making up 81.4% 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 67 entries, water accounts for 24.9% 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.

Compare the largest and smallest county equivalents in Florida 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.

How to read this table. Land and water areas are Census statistical measurements in square miles. Adding county rows can differ slightly from separately published state totals because of rounding and geographic treatment.
