How Big Is 100 Acres of Land? (With Helpful Visual Comparisons)


Not too long ago, we talked about the size of 10 acres of land, and then before that, one acre of land. Maybe you’ve come into quite a great deal more significant land than even 10 acres, say 100 acres? You’re excited about the possibilities, but first, you need to know how much land you have. So how big is 100 acres of land?

Since one acre is approximately 43,560 square feet, that makes 100 acres 4,356,000 square feet. In other words, the amount of land you own is tremendous!

Sometimes when you get into too many commas in a number, it gets really hard to visualize what it means in the real world. Fret not, as in today’s post, we’ll share plenty of really cool examples of how much 100 acres of land is and what it can be used for. Make sure you keep reading! 

Why 4,356,000 Square Feet? 

Does 4,356,000 square feet for 100 acres seem like an arbitrary number to you? That’s fair, but to understand why 100 acres is as many square feet as it is, you have to look at what one acre measures in square feet.

That’s 43,560 square feet. Yes, that number seems a bit arbitrary too, so let’s explain where it comes from a little, shall we? An acre is the area you get when you take a chain and a furlong, which is 66 feet by 660 feet respectively. 

A chain is indeed a unit of measurement, at least in this application. It’s always 66 feet or 22 yards. You can divide chains into rods, of which one chain is 4 rods, with a rod being a measurement of meters. You can also divide chains into links, which is 66/100th of a United States survey foot.

Of course, we’re talking about acres here, so we’re not delving any further into rods or links than that. Getting back to chains, chains constitute furlongs, with 10 chains making one furlong. What’s a furlong, then? To explain it as we did in that post about 10 acres, a furlong is 1/8th of a mile or 660 feet. Other equivalencies include 40 rods (okay, so there’s rods one more time) or 220 yards.

To calculate an acre, you need to multiply the furlong by the chain. If you super-sized your multiplication, you’d reach 4,356,000 square feet for 100 acres. 

Visualizing 100 Acres of Land: 7 Awesome Examples

If you’re still having a hard time fathoming what owning 100 acres of land would be like, then take a look at this video. It’s from a realty YouTube channel for a UK property, but it shows how wonderfully expansive 100 acres truly is.

Here are some cool examples of things that are equivalent of 100 acres so you can see just how much land we’re talking here! (Hint: it’s a lot.)

About on Par with the Mall of America

The Mall of America in Bloomington, Minneapolis is considered the biggest mall in the United States. Open since 1992, the mall attracts visitors from all over due to its huge size. Just how big is the Mall of America? Well, 5.6 million square miles of course. If you own 100 acres of land, that’s 4.4 million square miles, so you’re close to having enough space to replicate one of the largest landmarks in the US.

60 Acres Less Than the Public Parts of Disneyland

ANAHEIM, CALIFORNIA – September 20th 2015 – The Disneyland Castle at night celebrating the 60th anniversary.

Disneyland in Anaheim, California has been a worldwide attraction since opening its doors in 1955. Although it’s outsized by Disney World in Orlando, Florida, Disneyland’s public parts (aka, those you can use) are 160 acres in all. 

That’s enough space to fit Tomorrowland, Fantasyland, Frontierland, Adventureland, and Main Street, U.S.A with room to spare. With 100 acres of land for you, you have only 60 acres less than all those public parts of Disneyland! 

Twice the Size of Grand Central Station

Grand Central Station in Midtown Manhattan is a train station, yes, be the terminal also includes dining, shopping, and loads of cultural relevance. A landmark favored globally, Grand Central Station is only 48 acres. You have a little more than twice the amount of space than a whole Grand Central Station with your 100 acres of land.

Almost Eight Times Larger Than Windsor Castle

Grounds and garden of Windsor Castle near London, England, Europe

The breathtaking Windsor Castle in Berkshire, UK resides on gorgeous countryside. Dating back nearly 1,000 years, the castle is an architectural wonder that’s also renowned for housing lineages of the British royal family, including the current Queen. 

Windsor Castle has 1,000 rooms, most of which are allowed to be visited by the public. Even still, with all that space, the castle is only 13 acres, smaller than even nearby Buckingham Palace, which is 19 acres.

You’d have more than 80 acres of space compared to Windsor Castle, where the Queen splits her time! 

65 Times the Size of the White House

White House

We don’t have royalty in the US, but we do have our President of the United States. This esteemed political official lives in the White House, which is a stately building in Washington, DC. Have you ever wondered how big the White House is? 

Although the White House itself sits on 18 acres of land, the house itself is 1.50 acres. That’s enough room for six stories with 35 bathrooms, three kitchens, 16 guest and family rooms, and 132 other rooms. 

You’d have 65 times the space of the White House with 100 acres of land! 

800 Times That of an NBA-Approved Basketball Court

Do you feel like shooting some b-ball? You’d have more than enough room on 100 acres of land. The NBA mandates that a basketball court is 16.764 meters in width by 29.56565 meters in length. If you calculate those meters into acres, you get 0.12247474750 acres. 

Your 100 acres of land, by comparison, is 816.48484540 the acres of one basketball court that NBA teams play on.

1,000 Times Bigger Than an IMAX Screen

When you go to the theaters to see a movie, do you prefer the experience on an IMAX screen? Who doesn’t, right? Those screens are so sizable that it seems foolish to watch a film on anything smaller.

Yet it turns out that an IMAX screen really isn’t all that big, well, at least when comparing it to 100 acres of land. An IMAX screen is 52 feet by 72 feet, which is 0.08752 acres. With 100 acres, you have approximately 1,143 times the space. 

How Long Does It Take to Walk Across 100 Acres?

Surely, since 100 acres is so very vast, you could get some great exercise walking around your expanse of land, right? Absolutely! To get the perimeter of one of your acres, we need to look at the square acreage per side. That’s 208.7 feet for each side, giving you an overall perimeter of 835 feet for the acres. 

That’s only 16 percent of one mile, so it’s not super-duper far. Assuming you walk at the normal average walking pace of 3 miles per hour, you can walk a mile in 20 minutes. 

What Can You Do with 100 Acres of Land? 

As the proud owner of 100 acres of land, you’re still scratching your head wondering what to do with all that space. Allow us to present a couple of suggestions! 

Make Your Own Amusement Park

Six Flags AstroWorld in Houston, Texas is 75 acres, California’s Great America is 100 acres, and Disney World’s Magic Kingdom is only 107 acres. You can see what we’re getting at here. With 100 acres of land to your name, you can easily build an amusement park that’s very spacious.

This wouldn’t have to be a private park either, but one that’s open to the public for thousands and thousands of families to make timeless memories. 

Start a Housing Community

In our post about how big 10 acres is, we mentioned that a spacious home is one that’s 2,400 square feet. With only 10 acres of land, you’d be able to accommodate 180 homes. By adding up your acreage to 100 acres in all, you could now build your own community of 180,000 homes. 

Build a Mall

Remember, you have just about as much space available as Minnesota’s Mall of America, the biggest of its kind in the US. Most malls are only 400,000 square feet, so you could build a few malls of normal size or one super-mega-mall.

Final Thoughts

If you’ve somehow been fortunate enough to receive 100 acres of land, you’re going to have so much land that you won’t know what to do with it all. Your land outpaces such monumental buildings as Windsor Castle, Grand Central Station, and the White House. You have nearly as much land as that used to build the Mall of America or Disney World’s Main Street U.S.A. No matter how you decide to use the land, you’re at no shortage of options!
