⚠️This fact has been debunked
The traditional myth claims paper cannot be folded more than 7 times (not 8). This was debunked in 2002 by high school student Britney Gallivan, who folded paper 12 times and derived the mathematical formulas explaining the actual limits. The myth persists because it's practically true for standard-sized paper in everyday conditions, but it's not an absolute physical law.
No matter its size or thickness, no piece of paper can be folded in half more than 8 times.
Can You Really Only Fold Paper 7 Times? Myth Busted
You've probably heard this one: no matter how big the paper or how many times you try, you can't fold a piece of paper in half more than seven or eight times. It's been repeated in classrooms, bars, and internet forums for decades. It's also completely false.
In 2002, a high school junior named Britney Gallivan got tired of hearing her teacher insist it was impossible. So she did what any determined teenager would do: she grabbed a massive roll of toilet paper and proved everyone wrong.
The 12-Fold Achievement
Gallivan didn't just break the supposed limit - she obliterated it. Using a single piece of toilet paper that stretched 4,000 feet long (three-quarters of a mile), she successfully folded it in half 12 times. She became the first person in recorded history to achieve 9, 10, 11, and 12 folds.
But here's what makes her achievement truly remarkable: she didn't just fold paper really well. She derived the mathematical formulas that explain exactly why the myth exists and what it actually takes to break it.
The Math Behind the Myth
Gallivan developed two equations - one for single-direction folding and another for alternating-direction folding. Her formulas proved that the limit isn't about some magical number of folds. It's about the relationship between paper thickness, length, and the exponential growth that happens with each fold.
Each time you fold paper in half, the thickness doubles. After seven folds, you're dealing with 128 layers. The problem isn't that eight folds are impossible - it's that you need an exponentially longer piece of paper to accommodate each additional fold.
Why the Myth Survives
Here's the thing: for normal-sized paper in everyday situations, the seven-fold limit is practically true. A standard piece of printer paper simply isn't long enough to achieve eight folds. When you factor in the physical limitations of human strength and the fact that paper tears under stress, seven folds becomes a real-world barrier.
The myth transformed from "physically impossible" to "impractical without special conditions." Try it yourself with an A4 sheet - you'll tap out around six or seven folds, not because of some cosmic law, but because you've run out of paper to work with.
Breaking Your Own Record
Want to beat the myth yourself? Your best bet is thin, long paper. Toilet paper works great because it's thin and you can unroll massive lengths. The key variables are:
- Paper thickness - thinner is better
- Paper length - you need exponentially more for each additional fold
- Folding direction - single-direction folding requires less length than alternating
- Paper strength - it needs to withstand the compression without tearing
Since Gallivan's achievement, others have pushed even further. The current Guinness World Record sits at 13 folds, proving once again that what seems impossible is often just... really hard.
