How to Calculate Land Area in Acres From Length and Width

Whether you are buying land, planning a farm, installing a fence, or designing a landscape, knowing the size of a plot in acres is useful. Acreage is commonly used for large properties, agricultural land, and development sites. If you know the length and width of a rectangular plot, you can quickly estimate its area in acres.

Use our Acreage Calculator to convert your land measurements into acres without doing the calculations manually.

What Is an Acre?

An acre is a unit of land area. One acre equals 43,560 square feet, or approximately 4,046.86 square meters. An acre does not have one fixed shape. For example, a 66 ft by 660 ft plot equals one acre, but many other length-and-width combinations can also equal one acre.

This makes acreage useful for measuring land of different shapes and sizes.

How to Calculate Acres From Length and Width

To calculate acreage, first find the total area of the plot. Multiply the length by the width. Then divide the result by 43,560 when both measurements are in feet.

$\text{Area in Acres} = \frac{\text{Length in Feet} \times \text{Width in Feet}}{43,560}$

For example, imagine a land plot that is 300 feet long and 200 feet wide.

• Length: 300 ft
• Width: 200 ft
• Total area: 60,000 sq ft

The plot is approximately 1.38 acres. Rather than converting the measurements yourself, enter them into the Acreage Calculator for an instant result.

When Is Acreage Calculation Useful?

Calculating acreage can help with many projects, including:

• Buying or selling property
• Planning farm fields and crop areas
• Estimating fencing materials
• Designing irrigation systems
• Calculating landscaping requirements
• Comparing land prices by acre
• Planning building or development projects

For irregular land, divide the property into smaller rectangles or simple shapes. Calculate the area of each section, then add the results to find the total acreage.

Measure Carefully for Better Results

For the most accurate estimate, use reliable measurements and keep both dimensions in the same unit. If you measure in meters, use a calculator that converts square meters to acres automatically. Property boundary surveys may be needed when legal accuracy is important.
