According to the United States Census Bureau, it has a total area of 73.76 M² (191.04 km²).

In the summer of 1889, M.A. Low, an official from Rock Island, visited the local railway station, under construction, and learned about his name. At the time, it was called Skeleton. Not loving the original name, he changed the station name to Enid, a character from the Idilli of the king of Alfred Tennyson. However, a more imaginative story of how the city owes its name is popular. According to that story, in the days following the race to the earth, some enterprising settlers decided to mount a chuckwagon and cook for their pioneer comrades, hanging a sign that said "DINS." Some others, freer settlers, turned that sign backwards to read, which, of course, came up with the word "ENID."

During the opening of the Cherokee Outlet in the land race of 1893, Enid was the site of a land registry office that is now held in his Humphrey Heritage Village, part of the Cherokee Strip Regional Heritage Center. Enid, the railway station, (now North Enid, Oklahoma) was the original site of the city approved by the government. It was planned by geometric W. D. Twichell, then Amarillo, Texas.

The Enid-Pond Creek Railroad War broke out when the Interior Department moved the government site five kilometers south of the station before the land run, which was then called South Enid. During the race, because of the Rock Island's refusal to stop, people jumped out of the train to claim their credit on the government-approved site. In the afternoon of the race, the population of Enid was estimated to be 12,000 inhabitants out of 80 acres (320,000 m²) of the town plan of Enid. Enid's original plan in 1893 was 6 blocks long for 11 blocks: the town square on the north-west end, the West Hill School (Jefferson) to the south-west, the Government Springs Park in the center-south and the East Hill School (Garfield) in the northeast corner. A year later, the population was estimated at 4,410, rising to 10,087 in 1907, the year Oklahoma became a state.

The city's history was captured in Cherokee Strip: To This writer of an Oklahoma Boyhood from the author who won the Pulitzer Marquis James Prize, who tells his childhood to Enid.

Enid lived a "golden period" after the discovery of oil in the region in the 1910s and until World War II. Enid's economy grew as a result of the demand for oil, wheat, and railway industries, and its population increased steadily during the early 20th century, coinciding with a period of substantial architectural development and land expansion. The center of Enid had the construction of several buildings including Broadway Tower, Garfield County Court and Enid Masonic Temple. In conjunction with the oil boom, oil tankers like T. T Eason, H. H. Champlin and Charles E. Knox built houses in the area. The creation of residential areas during this period includes Kenwood, Waverley, Weatherly, East Hill, Kinser Heights, Buena Vista and McKinley. Union Equity, Continental, Pillsbury, General Mills, and other wheat companies operated windmills and silos in the area, creating what is now the Enid Terminal Grain Elevators Historic District, and Enid earned the titles of "Wheat Capital of Oklahoma Grain Capital of Oklahoma), "Oklahoma's wheat queen city. Queen Wheat City of Oklahoma and Wheat Capital of the United States.
