Tarleton is located 65 miles (100 km) southwest of Fort Worth, Texas in Stephenville, the county seat of Erath County. With a population of 16,000, Stephenville provides a combination of small-town security and proximity to Dallas/Fort Worth. Most university activities take place on Tarleton's centrally located, 173 acre (700,000 m²) main campus. A 600 acre (2.4 km²) university farm and the 1,200 acre (4.8 km²) Hunewell Ranch provide additional educational facilities. Recently, Tarleton also began offering programs at its new Granbury location, the Dora Lee Langdon Cultural and Educational Center.
