Why newspaper is so dangerous: These types of paper cause the most cuts

We've all been there: quickly turning a page in a book or leafing through files – and suddenly your finger is bleeding. Paper cuts are one of the most common everyday accidents. But which types of paper are particularly dangerous?
Scientific study reveals risk factors
Researchers at the Technical University of Denmark have conducted the first systematic study of which types of paper cause the most cuts. Their surprising finding: the physics behind paper cuts was previously completely unclear.
The research team used ballistic gelatin—known from weapons research—to test different types of paper. They systematically examined thickness, strength, and cutting angle.
Newspaper and printer paper: the most dangerous types of paper
The study in the journal “Physical Review E” clearly shows that newspaper and printer paper with a thickness of around 65 micrometers cause the deepest cuts. This average paper thickness proves to be particularly treacherous.
Why is newspaper so dangerous?
Newspaper combines three dangerous characteristics:
• Optimal thickness: approximately 65 micrometers—thick enough for stability, thin enough for sharp edges
• Firm structure: does not deform upon contact with skin
• Sharp edges: small surface area concentrates pressure
These types of paper are also dangerous
The researchers identified other risk candidates:
• Post-it notes: Surprisingly sharp edges
• Printed magazines: Similar properties to newspaper
• Office paper: Standard paper used in offices
Harmless types of paper: All-clear for thick and thin paper
Tissue paper proved to be relatively harmless—it warps on contact and is therefore difficult to cut. Photo paper is also harmless, as the thick edges have too large a surface area.
The perfect cutting angle makes all the difference
The angle is also crucial: paper must hit the skin at a slight angle in order to cut. If it hits straight on, nothing usually happens.
Practical test: the “paper machete”
The researchers even developed a “paper machete” – dot matrix printer paper on a scalpel. They successfully cut vegetable peels and meat with it. This shows that paper can be surprisingly sharp.
Conclusion: Be careful with newspapers and office paper
Newspaper and printer paper pose the highest risk of injury. Their average thickness of 65 micrometers makes them perfect “cutting tools.” Particular caution is advised when handling Post-its, magazines, and office paper.
Tip: Protect your fingertips when leafing through files or newspapers and make slow, controlled movements.
