Land area: Haskell County and the closest-sized states
Haskell County577.5 mi²
Rhode Island1,033.9 mi²

Another way to picture it: the same land area would fill a square about 24 miles (38.7 km) on each side. Real county shapes are rarely square, so this is a scale reference rather than a width or driving distance.

State figures are the sums of each state’s county-equivalent land measurements in the same Census release, so states and counties are compared on the same basis. Published state totals can differ slightly because of rounding. Compare all states · Counties bigger than entire states.
