From east to west, Hawaii is the widest U.S. state, measuring 1,500 miles from the island of Niihau to the island of Hawaii. At only 6,423 sq. mi. of land area, though, it still can't mess with Texas: it would take approximately 40 Hawaiis to match the total size of the Lone Star State. California is about 24 times as large as Hawaii; even New York is about seven times as big. The Aloha State still beats Connecticut, Delaware and Rhode Island, however. So there.
