Acreage Calculator – Find the Size and Area of Your Land

Find Acres Using a Map or By Entering the Land Length and Width

The area of a complex shape of land can be found using a map by placing markers on the edges of the land to be measured, or for simple land areas enter the length and width of the property and select the unit of measurement.

Horse pastures often require a lot of land and acreage

What is an Acre

An acre is a measurement of area, and so it is calculated like other area measurements, which involves multiplying the length by the width in a standard unit. An acre is a unit of measurement used to signify the area of a parcel of land. Acreage is essential for real estate and land transactions, where the price of land is typically dependent on the size of the property, in acres.

How Big is an Acre

An acre is a piece of land that is 43,560 square feet, or roughly 208.7′ x 208.7′. To help visualize, that’s just a little bit smaller than a football field. An acre equates to .4047 hectares or 4,047 meters2. To find how big an acre is in other units of measure, check out our acreage unit conversion tool.

1 acre is equal to:

  • 6,272,640 inches2
  • 43,560 feet2
  • 4,840 yards2
  • 0.0015625 miles 2 (640 acres = 1 mile2)
  • 160 perches
  • 4 rods
An acre is an area that is equivalent to a 208.7' x 208.7' parcel of land

How to Find Acres

The calculator above can help find the size of your land in acres by simply entering the length and width values. Calculating the size of an acre can be done by calculating the square feet of land, then dividing by 43,560 to determine the size of the land in acres.

To find square footage, multiply the length of the area in feet by the width of the land in feet. Use our square footage to acres conversion tool to convert square feet to acres. If you know the size of the land in square meters, you can convert square meters to acres using our square meters to acres conversion tool.

Property is not commonly divided into perfect squares and finding the acreage of irregular shapes can be a little more challenging. If the land can be broken down into smaller geometric shapes, you can find the square footage of those smaller shapes separately and then add together. Use our interactive map to determine the actual square footage of significantly irregular shapes.
