How Many Oreos to Cover the US? Have you ever wondered just how many Oreos it would take to blanket the entire United States? This fun (and slightly absurd) question combines math, geography, and snack food trivia into one delicious thought experiment. In this article, we’ll break down the calculations step by step to estimate how many Oreos would be needed to cover the U.S., along with some surprising comparisons along the way.

Step 1: Determining the Surface Area of the United States
The first step in answering this question is figuring out the total land area of the United States. According to the U.S. Geological Survey:
- Total U.S. land area: ~3.8 million square miles (~9.8 million square kilometers).
- Excluding water bodies: For simplicity, we’ll focus on land only.
Converting to Square Inches (For Oreo Measurements)
Since Oreos are small, it’s easier to work in square inches:
- 1 square mile = 4,014,489,600 square inches
- Total U.S. land area in square inches:3.8 million sq mi×4.014 billion sq in/sq mi≈1.525×1016 sq in3.8 million sq mi×4.014 billion sq in/sq mi≈1.525×1016 sq in
Step 2: Measuring an Oreo’s Coverage Area
A standard Oreo cookie has:
- Diameter: ~1.75 inches
- Area (single side, assuming circular coverage):πr2=π(0.875)2≈2.405 square inchesπr2=π(0.875)2≈2.405 square inches
Accounting for Gaps Between Oreos
If we assume perfect hexagonal packing (like a honeycomb), Oreos would cover about 90.69% of the surface. So, the effective coverage per Oreo is:2.405 sq in×0.9069≈2.18 sq in2.405 sq in×0.9069≈2.18 sq in
Step 3: Calculating the Total Number of Oreos Needed
Now, divide the U.S. land area by the effective Oreo coverage:1.525×1016 sq in2.18 sq in/Oreo≈7×1015 Oreos2.18 sq in/Oreo1.525×1016 sq in≈7×1015 Oreos
Final Estimate:
- ~7 quadrillion Oreos (7,000,000,000,000,000) to cover the U.S.
Putting This Number Into Perspective
1. How Long Would It Take to Produce That Many Oreos?
- Nabisco produces ~40 billion Oreos per year.
- To make 7 quadrillion Oreos:7×101540×109=175,000 years40×1097×1015=175,000 years(Yes, you’d need 175 millennia of continuous production!)
2. Stacking Oreos to the Moon
- 1 Oreo ≈ 0.3 inches thick.
- Distance to the Moon: ~238,855 miles (~1.26 billion feet).
- Stacking 7 quadrillion Oreos:7×1015×0.3 in≈33 million miles7×1015×0.3 in≈33 million miles(That’s enough to reach the Moon and back 70 times!)
3. Weight Comparison
- 1 Oreo ≈ 11.3 grams.
- Total weight of 7 quadrillion Oreos:7×1015×11.3 g≈79 trillion kg7×1015×11.3 g≈79 trillion kg(That’s heavier than all humans on Earth combined!)
Alternative Approach: Covering Just Roads or Cities
If covering the entire U.S. seems excessive, let’s look at smaller areas:
1. Covering All U.S. Roads
- Total U.S. road area: ~61,000 sq miles (~2.45 × 10¹⁴ sq in).
- Oreos needed: ~112 trillion.
2. Covering New York City
- NYC land area: ~302 sq miles (~1.21 × 10¹² sq in).
- Oreos needed: ~555 billion.
FAQs About Oreo Coverage
1. Would the Oreos stay in place?
- Unlikely! Wind, rain, and wildlife would scatter them quickly.
2. How much would 7 quadrillion Oreos cost?
- At ~$0.20 per Oreo, it would cost ~$1.4 quadrillion (more than global GDP!).
3. Could we actually make that many Oreos?
- No—global wheat and cocoa supplies couldn’t support it.
4. Has anyone tried covering a large area with Oreos?
- The largest Oreo “carpet” was 1,852 Oreos (Guinness World Record, 2021).
5. What if we used Double Stuf Oreos?
- Same coverage (same diameter), but twice the cream!
6. How long would it take to lay them all out?
- If 1 person laid 1 Oreo per second, it would take 220 million years!
Final Thoughts
While 7 quadrillion Oreos is an unimaginably large number, this fun calculation highlights just how vast the United States is—and how mind-bogglingly huge numbers can get when scaling up everyday objects.
Key Takeaways:
✔ 7 quadrillion Oreos would be needed to cover the U.S.
✔ Producing that many would take 175,000 years.
✔ The stack would reach the Moon 70 times over.
✔ It’s a fun math exercise—not a practical project!

Did You Know?
- The Oreo brand sells ~40 billion cookies annually—enough to cover 5 football fields.
- If you stacked all Oreos made in a year, they’d reach 1/5 of the way to the Moon.
