A quarter section, often shortened to quarter, is an area of one-fourth of a square mile, or 160 acres (0.65 km2). It was a common size of a tract under Homestead Acts in the United States and the Dominion Land Survey in Canada.
How many acres in a section? An acre measures 43,560 square feet which is roughly 208.71 feet on a side. A section (one square mile) measures 27,878,400 square feet. Divide 27,878,400 by 43,560 and that equals 640 acres in a section. A half (1/2) section is 320 acres.
