๐ Paper Folding Thickness Calculator
Enter a sheet of paper's thickness and a number of folds to calculate how thick it would become after being folded in half that many times. Because thickness doubles with every fold, it grows exponentially โ even a thin sheet reaches astonishing thickness after just a few dozen folds. Also shows the theoretical number of folds needed to reach the Moon or exceed Mt. Fuji's height.
How to use
- Enter the starting thickness of the paper (in mm).
- Enter the number of folds โ the resulting thickness is calculated automatically.
- See the theoretical number of folds needed to reach the Moon or Mt. Fuji's height.
FAQ
Why does folding paper get so thick so fast?
Because the thickness doubles with each fold โ exponential growth. A sheet just 0.1mm thick would theoretically exceed the distance to the Moon after only 42 folds.
Can I actually fold a sheet of paper that many times?
In practice, no โ the paper's area is halved with every fold, so a normal sheet of paper can usually only be folded about 7-8 times before there's no room left to fold. This calculator shows the theoretical thickness only.
Where do the Moon distance and Mt. Fuji height figures come from?
This uses the commonly cited average Earth-Moon distance of about 384,400 km and Mt. Fuji's height of about 3,776 m.
