The King Ranch in South Texas spans approximately 825,000 acres (1,289 sq mi). The state of Rhode Island covers about 1,544,750 acres (2,414 sq mi).
Rhode Island is nearly twice the size of King Ranch. The ranch covers roughly 53% of Rhode Island's land area. While King Ranch is one of the world's largest ranches—larger than some U.S. states (e.g., Delaware at 1,254,000 acres)—it does not surpass the Ocean State.
