Measure the length of the land in feet
Measure the width of the land in feet
Multiply length by width to get square feet
For irregular land shapes, divide the land into smaller simple shapes
Calculate the square feet of each shape separately
Add all the square feet values together
Use a survey plan or plot map for more accurate measurements
Convert other units to feet before calculating if needed
Square feet = length × width for rectangular land
Square feet = total area of all measured sections for irregular land
