How Big is an Acre? 5 Tips for Estimating Land Size 

How big is an acre of land? Follow along as we discuss how big an acre is and how to estimate land size accurately. 

Buying a home is one of the most significant purchases you will ever make, so you must understand all the terminology and measurements as you look for your dream home. One of the measurements you'll come across is the land size measured in acres, which is separate from the house size measured in square feet. 

So, how big is an acre? Is it a lot of space to upkeep and maintain? How expensive is an acre? How can you estimate the size of your land? These are all questions that we will answer. So, keep reading; this guide will help you understand land measurements and tell you everything you need about acreage. 

What is an Acre?

An acre is the preferred unit of measurement for land in the United States, equalling 43,560 square feet. Numbers are just numbers, so how can you visualize an acre? You can think of an acre as about 90% of a football field, 16 tennis courts, or nine basketball courts. An Acre can be measured in any shape, from rectangles to circles or even hexagons. The most common form for an acre is one furlong by one chain or 660 feet by 66 feet.

According to Encyclopedia Britannica, the size of an acre was initially derived from the amount of land that could be plowed in a day with a yoke of oxen pulling a wooden plow. It is said that the root word stems from the Latin word ager, which means field.

Today, determining the size of an acre based on oxen pulling a wooden ploy would be inaccurate and could vary drastically. Think of it this way, a farmer with a large team and the best oxen in town could plow a field a lot faster than a single farmer with smaller, tired, or weak oxen. 

It was in the 13th century that we better understood how to calculate an acre. Edward I of England defined an acre as four rods wide by 40 rods long, with one rod being 16.5 feet. 

(4 rods X 16.5 feet) X (40 rods X 16.5 feet) = 66 feet X 660 Feet = 43,560 square feet

This measurement is still used today and is used across nearly two dozen countries and territories. The Weights and Measures Acts were enacted in England to standardize the length of an acre, so when English settlers came to America, they used the acre as their unit of measurement. 

Acre is square feet 43,560 square feet
Acre in square yards 4,840 square yards
Acre in square meters 4,056.86 square meters
Acre in square hectares 0.405 square hectares
Acre in square miles 0.00156 square miles 
Acre in square kilometers 0.00404 square kilometers

How to Measure Your Lot Size 

When buying a home, you want to understand how much land you're getting clearly, and you can always trust listing sites, or you may inherit land without information. If you want to estimate your land size independently, here are a few easy tips. 

1. Manually Measure 

Manually measuring your lot size is the most time-consuming. You can walk around the property line with a measuring tape or wheel. When using a measuring wheel, you will roll out and multiply both directions. You can also use google maps to track your movement as you walk the lot's perimeter, leaving you with accurate dimensions.

Let's say you have a parcel of land that measures 500 feet in length and 650 feet in width:

Length = 500 feet; Width = 650 feet 

Area of Land = Length X Width 

= 500 X 650 

= 325,000 square feet 

= 325,000/43560 acres 

= 7.46 acres 

2. Locate the Deed 

Often, the deed or documents that come with the house will include pictures of the land or details that you can use to determine your lot size. To get your lot size, you can input the information into a calculator, including length and width. The deed will contain details such as the description of the property and the measurement of each of the lot's boundaries. 

3. Property Plat Map 

If you have recently purchased or inherited property, you will have received a plat map at the closing. The plat map will include the lot layout, the boundary dimensions, and the tax parcel identification number. 

4. Survey 

Hiring a professional surveyor will give you an accurate description of your lot size. However, it may be the most expensive option.

5. Pacing 

Pacing may be the least accurate way to estimate your lot size. Pacing includes walking the length and width of your size, using one of your steps as the measurement. After evaluating the number of steps, a quick math calculation will give you an estimate of your lot size. 

3. Documents That May Contain the Lot Size or Help you Determine 

  • Property Deed
  • Property Plat Map 
  • Subdivision Plat Map 
  • Boundary Survey Plan 
  • Existing Conditions Plan 
  • Tax Map 
  • Local GIS
  • Professional Survey Services 
  • Pacing 
  • Measuring Wheel 

How to Calculate Square Feet To Acres?

This calculation is easy and simple. As said before, there are 43,560 square feet in one acre so you would multiply your figure by 43,560. Here are a few examples: 

  • 1 acre = 43,560 square feet 
  • 2 acres = 87,120 square feet
  • 3 acres = 130,680 square feet
  • 4 acres = 174,240 square feet
  • 5 acres = 217,800 square feet 

and so forth. You can also easily calculate the acreage of your land by giving the square feet. You will take your land square feet and divide it by 43,560. For example, if you have a piece of land that is 550,000 square feet, you will divide it by 43,560, which equals 12/6 acres. 

How Much Does an Acre of Land Cost? 

Those wondering how big an acre is are often also wondering how much an acre costs. According to the USDA, the average cost of an acre in the United States in 2022 was $3,800. However, land in bigger states and popular metro areas will be more expensive.

Residential land can either be or less. In undeveloped areas, the cost of an acre will be cheaper than land in developed areas where roads, housing, and others are easily accessible. The average price of an acre in North Carolina is $4,600.

The states with the highest price per acre are: 

  • New Jersey 
  • Rhode Island
  • Connecticut
  • Massachusetts
  • Maryland
  • Delaware
  • New York 
  • California
  • Pennsylvania

The states with the lowest price per acre are: 

  • New Mexico 
  • Montana: average $2,283 per acre
  • Wyoming: average $1,558 per acre
  • North Dakota: average $2,936 per acre
  • Nebraska: average 2,936 per acre
  • Kansas: average $4,220 per acre
  • Nevada: average $2,116 per acre
  • Arizona: average $4,328 per acre
  • Idaho: average $3,435 per acre

What Affects the Cost of an Acre of Land? 

Many things can drive the cost of an acre up or down. The price can be affected by location, use, zoning, scarcity, and size. Location is a significant factor as an acre of land in the midwest will likely cost you way less than an acre in California or where the cost of living is higher. How close the land is to flood zones and other hazards will also drive the cost of an acre down. 

Infrastructure can also affect the cost of an acre. Land already developed with electric connections, sewer hookups, and paved roads will likely be more expensive than raw, undeveloped acreage. 

Another common price factor is the topography of a plot of land. Land that is level ground with good drainage will be more expensive than the latter. Homebuyers will also pay more for land that has a good view. 

Lastly, the economic activity in your area can significantly affect the cost. You will pay more for land in areas with intense economic activity and more opportunities. 

Benefits of Acreage 

Privacy 

The more acreage you have, the more privacy you will receive. There will be more space between you and your neighbors, you won't hear the people next door, and you won't have to worry about neighbors seeing into your windows, as they are too far away. 

Building Opportunities 

You can use it to your advantage when you have an abundance of acreage. You can build onto your current home, a detached mother-in-law suite, a guesthouse for visitors, and more because you have the space to do so.

Space for Outdoor Activities 

People often buy homes with more acreage to build up their outdoor space. There is more space to play and explore and more space to add a pool, build a deck, or add sports courts.

Commercial vs. Residential Acre 

A commercial acre is an area that remains in a commercial real estate development project after improvements have been made, including by not limited to such improvements as curbs, sidewalks, and gutters.

A commercial real estate development could be a store, office building, warehouse, or factory. Commercial acreage is 82.6% of the standard, meaning 36,00 square feet, 4,000 square yards, or 3342.8 square meters.
