When Seth Wheeler filed his toilet paper patent application on June 8, 1891, the accompanying drawing showed the paper hanging over the front of the roll. That image has fueled a debate that still resurfaces today: should toilet paper be placed 'over' or 'under'?
U.S. Patent No. 465,588, identified in the patent record as US465588A, was granted to Wheeler on December 22, 1891. It is often cited as proof that the 'over' position is correct. But, the patent concerned improvements to rolled paper that made individual sheets easier to separate, not hygiene standards. Its design included prepared separation points, including incisions and edges that were serrated or weakened, to help users tear off sheets. The illustration reflects how Wheeler depicted his invention, not a universal rule for bathrooms or a medical recommendation.
The Patent’s Real Message
Wheeler’s patent drawing clearly shows the paper passing over the top of the roll and hanging at the front, making the end easy to find and grasp. The technical description focuses on the mechanics: lateral incisions and serrations help users locate the edge, while close joins connect the sheets. The patent covers the construction and separation of rolled sheets; its illustration documents a configuration, not a hygiene standard. Using the patent as a historical reference is accurate, but treating it as a medical guideline is a stretch.
Why 'Over' Might Be More Convenient
Supporters of the 'over' method point to practical benefits. The end of the roll is visible and easier to grab, often keeping it away from the wall. Christian Moro, associate professor of biomedical sciences at Bond University, notes that this can reduce accidental contact with the wall, a minor but real hygiene consideration. For people with limited mobility or dexterity, the 'over' position can make daily life easier. It also lets users see how much paper remains. But, the impact depends on the type of holder and the space between the roll and the wall. In some Spanish homes, bidet showers or other hygiene solutions are used alongside toilet paper, but none of these factors makes 'over' the only correct choice.
The Case for 'Under'
Advocates for the 'under' position argue that it lets users pull the paper with one hand while touching less of the exposed roll. Primrose Freestone, a clinical microbiology specialist at the University of Leicester, has highlighted this point. Others counter that searching for the end behind the roll can bring fingers or paper closer to the wall, potentially increasing contact with contaminated surfaces. No experimental studies directly compare the two methods. Research does show that bathroom surfaces can harbor microbes, but there is no evidence that one orientation is safer than the other. In homes with young children or pets, the 'under' method can make it harder for them to unroll the paper, an advantage for some families.
Handwashing Matters Most
Modern hygiene guidelines, including those updated by the World Health Organization in 2025, emphasize handwashing after using the toilet as the basic to preventing the spread of germs. The Spanish Ministry of Health also stresses that proper hand hygiene reduces the risk of transmission. Neither organization specifies how toilet paper should be hung. A recent study in Scientific Reports visualized how toilet flushes can send aerosols up to 1.5 meters in seconds, but did not examine toilet paper orientation. The advice is to keep the holder clean and prevent the paper from touching surfaces. Above all, wash your hands thoroughly.
Some viral household tips, such as using orange peels in the toilet, have also circulated online, but experts agree that nothing replaces proper cleaning. The 'over' method may be more accessible, while 'under' can be practical for families with children or pets. The choice comes down to personal preference and bathroom setup.
Debates over household habits are nothing new. In discussions about laundry hacks, including the viral aluminum foil trick covered in this earlier report, experts often remind us that convenience and hygiene are not always the same thing. The most impressive factor remains what happens after you reach for the roll: washing your hands.
