Do the math. You probably know how to calculate the square footage of a simple room without any funny shapes. Just break out your measuring tapeâor a laser measureâto get its length and width. Multiply the width by the length and voila! You have the square footage. Say a room is 20 feet wide by 13 feet long, then 20 x 13 = 260 square feet. How to calculate square feet.
1 square foot = approximately 0.000022959 acres. 1 acre = 43,560 square feet. To calculate the area of a room in square feet, measure the length and width of the room in feet, then multiply these figures together to give an area in ftÂ².For example, a room measuring 12 ft x 15 ft would be described as having an area of 180 ftÂ² (12 x 15 = 180). 1 square yard (Sq Yd) = 9 ftÂ². 2  One yard is three feet, so a square yard can be imagined as a square with sides of three feet, or a square block comprising nine individual squares with sides one foot in length.
