Calculate lot size in square feet, acres, square yards, square meters, hectares, and square miles. Estimate frontage, depth, perimeter, buildable area, setbacks, lot coverage, land value, and property size for residential lots, parcels, building sites, yards, and land planning.
Frontage × depth:
The calculator multiplies lot frontage by lot depth to estimate lot size in square feet and acres.
Length × width:
Use this mode when you know the full length and width of a rectangular lot.
Irregular lot estimate:
Enter front width, rear width, left depth, and right depth to estimate lot size using average width and average depth.
Known lot area conversion:
Enter a known lot size to convert it into square feet, acres, square yards, square meters, and hectares.
A lot size calculator helps estimate property size, land value, buildable area, lot coverage, and common land area conversions.
It can be useful for home lots, vacant land, subdivision planning, real estate listings, building sites, yard planning, zoning checks, landscaping, and property comparisons.
Your result shows estimated lot size in square feet, acres, square yards, square meters, hectares, perimeter, buildable footprint area, setback-adjusted buildable area, maximum lot coverage, and estimated land value.
For a rectangular lot, multiply frontage by depth. For example, an 80 ft by 125 ft lot is 10,000 square feet.
Divide the lot size in square feet by 43,560 to convert square feet to acres.
Lot frontage is the width of a property along the road, street, or front property line.
No. Lot size is the full property area. Buildable area may be smaller because of setbacks, easements, zoning rules, lot coverage limits, slopes, wetlands, or utilities.
