Quick Facts

  • An acre is a unit of area measurement that is equal to 43,560 square feet.
  • it is is the equivalent of 4,840 square yards or 208.71 feet by 208.71 feet.
  • It is equal to 1/640 of a square mile.


When it comes to understanding the size of land, an acre is a common unit of measurement. 

What is an Acre

An acre is a unit of land measurement that specifically refers to an area of land.

It is commonly used in the United States as well as in many other countries, such as the United Kingdom.

The term “acre” originates from the Middle English word “aker,” which derives from the Old English “æcer.”

This root word stem signifies a unit of land primarily used in agricultural contexts.

Acre as a Standard Measurement

The acre is widely used as a unit of land measurement, particularly in real estate and agricultural sectors.

It helps in determining the size of a parcel of land and provides a standardized approach for assessing land value, whether for commercial or residential purposes. It serves as a fundamental unit mentioned in property deeds, land surveys, and legal documents.

Historical Significance

The acre has a rich historical background that dates back to medieval times. It originated from the concept of what land a yoke of oxen could plow in a day.

This practical measure was shaped by the capabilities of farming equipment during that era.

As English settlers expanded their settlements and agricultural activities in the New World, the acre’s concept was embraced and carried forward.

While the international acre is the most commonly used form, it is worth mentioning that there are some regional variations.

For instance, the US Survey Acre measures slightly larger than the international acre, totaling 43,560.174 square feet.

However, these variations are relatively minor and do not significantly impact the general understanding and application of the acre as a unit of measurement.

We will also help you understand the actual size of an acre by providing simple conversions from square feet. 

To help you visualize it better, we’ll compare an acre to common objects and even sports fields. 

And, we will discuss variations of an acre [including commercial and builders’ acres], and how they impact the value of land.

Whether you’re a landowner, a real estate agent, or just curious about land measurements, this will provide practical examples and knowledge on what can fit in an acre and how it translates into other land measurements.

Historical Origins of

The acre measurement has a rich history that dates back centuries. 

The English Settler Connection

The concept of the acre can be traced back to medieval England. During this period, land was often measured and divided for agricultural purposes.

English settlers brought this measurement system to various parts of the world, including the United States and the United Kingdom, where it still remains a standard unit of land measurement.

The Root Word Stem

The word “acre” has its roots in Old English and Middle English, derived from the root word “æcer,” meaning “cultivated land” or “field.” Originally, it referred to the amount of land a yoke of oxen could plow in a day, which varied in size depending on the strength and ability of the oxen.

The Statute of Land Measures Act

In 1215, the Magna Carta established the importance of clear land measurement standards.

However, it wasn’t until the Statute of Land Measures Act was passed in 1601 during the reign of Queen Elizabeth I that the acre became an official unit of measurement. This act standardized the acre as 4,840 square yards or 43,560 square feet.

The Acre in the United States

When the United States was being colonized, English measurement systems were brought over by the early settlers.

The acre played a vital role in property ownership and land distribution during the westward expansion.

It became a fundamental unit for measuring land area, allowing the establishment of property lines and the division of land into parcels.

The International Acre

While the standard acre is widely used, it’s worth noting that there are slight variations in the acre measurement depending on the country or region.

The International Acre, adopted in 1959, is defined as 4,046.85642 square meters, which is equivalent to 4,840 square yards or 43,560 square feet.

This standardization ensures consistency in global land measurement practices.

Understanding the Size of an Acre

An acre, a unit of measurement commonly used in land and real estate, encompasses approximately 43,560 square feet or 4,840 square yards.

The size of a NBA basketball court is 94 ft long by 50 ft wide, for a total of 4,700 sq. ft. 

You can fit just over 9 basketball courts inside an acre.

However, the actual acreage may vary depending on its shape, it would likely be about 208.71 feet wide. 

A Major League Baseball field is, on average, about 109,000 square feet. So you can’t fit this inside an acre

Knowing the size of an acre is valuable for various purposes, such as buying or selling land, planning landscaping projects, or determining property boundaries. 

From Acres to Square Feet: 

Visualizing just how big an acre is can be beneficial when you’re involved in real estate transactions, planning landscaping projects, or determining property boundaries. 

Check out these examples:

  • In 5 acres there would be 5 * 43,560 = 217,800 square feet.
  • 4 acres is equal to 174,240 ft.
  • 3 acres is equal to 130,680 ft.
  • An acre contains 6,272,640 square inches.
  • One acre is approximately 0.0015625 square mile

Keep in mind that acreage can vary in shape and dimensions, so it’s always recommended to consult with a surveyor or use online tools for accurate measurements.


Comparisons with Common Objects

An acre, which is approximately 4047 square meters, can be visualized by comparing it to various common objects. 

It’s also helpful to think of an acre as approximately the size of a city block in some urban areas. 

Additionally, an acre is about the same size as 16 tennis courts or roughly 75% of a soccer field.

Commercial and Builders Acreage 

An acre is a unit of measurement used to quantify land area. 

In commercial real estate, commercial acres are often used and typically measure 36,000 square feet or slightly less than one standard acre.

On the other hand, in construction, builders’ acres are commonly used and measure 40,000 square feet, which is also slightly less than one standard acre.

This is done without deducting for roads, driveways, sidewalks,  or structures.

How a Lot Size Impacts the Value of Land

Lot size plays a key role in determining the value of land. As you know by know the commonly used unit of measurement for land area is an acre.

With everything else being equal, a larger parcel of land will fetch more money. 

However, there are variations of the standard acre measurement that impact the value of land differently.

Remember commercial acres, which are typically smaller than the standard acre, are used for commercial real estate purposes.

On the other hand, builders acres, which are larger than the standard acre, are used in the construction industry to calculate lot sizes for residential developments.

Many people will only buy houses in Houston that sit on a specific acreage due to its future value.

Knowing the difference in the size of commercial and builders acres can help you adjust for its size.

 Common Uses of an Acre

Whether you are a farmer, a real estate agent, or simply curious about land sizes, understanding the common uses of an acre can provide valuable insights. Here, we explore the different ways in which an acre is utilized.

 Agricultural Land:

One of the most common uses of an acre is for agricultural purposes.

Farmers rely on acres of land to cultivate crops, raise livestock, and sustain their livelihoods.

An acre of agricultural land can yield a diverse range of crops, including grains, fruits, vegetables, or even vineyards.

It provides ample space for farmers to implement various farming techniques and practices.

Residential Plots:

In the realm of real estate, an acre is often subdivided into smaller residential plots.

These plots can be used to build single-family homes, townhouses, or even apartment complexes. A typical residential plot may vary in size depending on zoning regulations and the density of construction allowed in a particular area.

Recreational Spaces:

An acre of land can serve as a recreational oasis. Parks, playgrounds, and athletic fields are often designed within acreage to provide communities with a space for leisure activities.

A football field, for example, occupies roughly 1.32 acres, demonstrating how even a fraction of an acre can be utilized for specific sports or recreational pursuits.

What Else Can You Fit in an Acre

An acre can accommodate approximately 16 single-family homes. In agriculture, it can support around 2,000 tomato plants or 1,000 apple trees.

  • About 150 cars, assuming each parking space is about 300 square feet.
  • A small vineyard with about 400 grapevines.
  • An outdoors shopping or business park.
  • A small to mid-sized apartment building.

How Many Houses can you fit in one

  • If we consider the median size of a U.S. family home is roughly 2,300 square feet including the yard, you would be able to fit about 18-19 homes onto an acre of land
  • In urban areas with smaller lots, multiple houses or townhomes may be accommodated.

In suburban or rural areas, one acre might be enough for a single-family home and yard.

For most people, if you have a home that sits on an acre, thats pretty large.

The Impact of Land Shape on Acre representation

The shape of the land has a significant impact on how an acre is visually represented. 

In agriculture, an acre serves as a unit of measurement for determining the size of land used for farming and other agricultural purposes.

For instance, a square-shaped piece of land would have sides that are approximately 208.71 feet long, whereas a rectangular plot may have longer sides and shorter ends.

How Acres Translate into Other Land Measurements

When compared to hectares, an acre is around 0.4047 hectares, and it’s roughly 0.0016 square miles in terms of area.

Converting Acreage into Plots

To convert acres into plots, you need to be familiar with the size of a plot in your specific location.

Keep in mind that plot sizes can vary depending on local regulations and norms. 

  • For example, if a typical plot size in your area is 1/8th of an acre, then one acre would be equivalent to eight plots.

How Long Would It Take to walk across

The time it takes to traverse an acre depends on the method of traversal.

  • Walking leisurely across an acre may take around 10-15 minutes, while driving in a straight line at a moderate speed could take approximately 20-30 seconds.

Keep in mind that these times are estimates and can vary based on terrain and other factors.

What is the perimeter of an acre

It really doesn’t have a perimeter. However, if you were to convert an acre into square feet (43,560 square feet) and then assume it’s a square shape, each side would be about 208.71 feet – resulting in a total perimeter of around 834.84 feet.

What is the area of an acre

The area of an acre is 43,560 square feet.

Who decided that an acre should be 43,560 square feet

An acre was defined during the British Imperial system in the 19th and 20th centuries.

Is There a Standard Size for an Acre Worldwide

While different countries may have their own traditional or regional units, an acre remains the standard worldwide.

When dealing with land measurements internationally, it’s important to consider local regulations and conversions.

How many sections are in a square mile

In U.S. land surveying under the Public Land Survey System (PLSS), a section is an area nominally one square mile, containing 640 acres, with 36 sections making up one survey township on a rectangular grid.

Therefore, there is 1 section in a square mile, according to Wikipedia.

Who owns the most acres in the world. 

The British family owns 6.6 billion of them. (source: [Yahoo News]

What country encompasses the smallest amount of acreage

That would be the Vatican City that covers only 109 acres

How many acres are in the United States

There are approximately 2.43 billion acres in the United States.

How Has the Definition has Changed Over Time

The definition of an acre has evolved over time, but it has remained relatively consistent.

Originally, it was the amount of land that could be plowed in one day by a yoke of oxen.

Final Thoughts

It’s important to understand the size of an acre when it comes to land measurements. 

Whether you’re a builder, farmer, or homeowner who wants a cash offer, knowing the dimensions and variations of an acre can greatly impact your decisions and investments.
