Frequently asked questions
What does the Lot Size to Square Feet Calculator compute?
It turns a lot's dimensions into its total area. You enter length and width in feet, and it returns square feet plus the acreage.
What is the formula behind it?
Lot size in square feet equals length times width. Acres equal that result divided by 43,560.
Can you give a worked example?
A 50 by 100 foot lot is 5,000 square feet, which is about 0.11 acres.
What if the lot is not rectangular?
For odd shapes, divide the lot into rectangles and triangles on paper, calculate each piece, and add them. A surveyor's plan gives the most reliable total.
