The amount of area that one acre covers depends on the shape of the parcel. The most common way to measure an acre is by square footage, which is 43,560 square feet in a full acre. A half-acre lot measures about 21,780 square feet, or half of a full acre.

If you have a rectangular piece of land, divide it into rectangles and then calculate how many rectangles fit into your lot. For example, if you have a lot that’s 50 feet wide by 100 feet long and you divide it into 10-foot-by-10-foot squares, you’ll get 100 squares total because there are 10 x 10 = 100 squares total. These squares represent your half-acre lot.

If your property isn’t rectangular or round but rather has an irregular shape or some other unusual configuration, you’ll need to calculate the area using different methods. For example, if your property is shaped like an X with two small sections attached at either end of the X and large sections in between them (like an upside down “V”), then you’ll need to figure out how many square feet make up each section separately before adding them together to get the total square footage for your entire lot.
