How to Calculate Acreage
Calculating land acreage is an essential step for property owners, real estate agents, landscapers, and farmers. An acre is a historical standard unit of land area commonly used throughout the United States and the United Kingdom.
Whether you are evaluating a rectangular parcel or a complex irregular rural tract, you can either enter length and width dimensions directly or outline your parcel boundary on the interactive map above.
The Acreage Formula
Area (sq ft) = Length (ft) × Width (ft)
Acres = Area (sq ft) / 43,560
Acres = Area (sq ft) / 43,560
If you have measurements in meters or yards, convert them to feet first (1 yard = 3 feet; 1 meter ≈ 3.28084 feet) or select the appropriate unit in the dropdown above to let our tool convert the values automatically.

Frequently Asked Questions
How many square feet are in one acre?▼
One acre is exactly equal to 43,560 square feet. For a square acre, each side is approximately 208.71 feet long.
How do I calculate acreage from length and width?▼
Multiply the length in feet by the width in feet to determine total square footage, then divide that number by 43,560. For example: 300 ft × 500 ft = 150,000 sq ft; 150,000 / 43,560 = 3.4435 acres.
Can I measure irregular land plots on the map?▼
Yes! Switch to the 'Measure on Map' tab above, locate your property, and click around the perimeter boundary to calculate acreage instantly in real time.
Are my property measurements uploaded to your server?▼
No. All geometry and dimension computations run entirely client-side in your web browser. Your coordinates and measurements are completely private.
