How the land area calculator works

Rectangular land mode:
The calculator multiplies land length by land width to estimate area and perimeter.

Multiple parcels mode:
The calculator multiplies one parcel area by the number of same-size parcels.

Known area mode:
The calculator starts from your known land area and converts it into acres, hectares, square feet, square meters, and more.

Circular land mode:
The calculator uses diameter to estimate circular land area and boundary length.

Why use a land area calculator?

A land area calculator helps estimate lot size, field size, farm acreage, yard area, parcel area, property value, fencing length, and land measurement conversions.

It can help calculate square feet, acres, hectares, square yards, square meters, square miles, perimeter, fence length, land value, and estimated annual tax.

What your result means

Your result shows land area in square feet, acres, hectares, square yards, square meters, square miles, and square kilometers. It also estimates perimeter, fence length, land value, fence cost, and annual tax based on your inputs.

Land area formulas

Frequently asked questions

How do I calculate land area?

For a rectangular parcel, multiply the land length by the land width. Then convert the result into square feet, acres, hectares, or other units.

How many square feet are in an acre?

One acre equals 43,560 square feet.

How many acres are in a square mile?

One square mile equals 640 acres.

How do I estimate fence length for land?

Use the land perimeter, then subtract gate openings or access openings. For a rectangular parcel, perimeter equals 2 times length plus width.

Is this land area calculator exact?

No. It is an estimate. Actual property area can vary by survey boundaries, irregular shapes, easements, slopes, roads, water, exclusions, and recorded parcel measurements.
