This is one of those list where being consolidated with rural areas and suburbs pays off. For example, this list compares Jax (all +767 square miles) with urban inner suburbs like Camden, NJ (8.8 square miles) and Miami Gardens (20 square miles).
Some other spacious and/or consolidated cities are ahead of Jacksonville on that list - Memphis, Houston, Oklahoma City, Nashville, Indianapolis, Charlotte.
