There is only one correct way to place toilet paper. A patent ended the debate in 1891

We have been fighting all kinds of battles for centuries, and in some cases the response passed between disputes between each other. Among these debates there is one that never seems to disappear because both sides are equally clear about it. We are referring to toilet paper and correct way to hang it. If it takes us decades to achieve a significant advance of the roll, it makes sense that the controversy has endured.

The funny thing is that the answer was there from the beginning.

A “war” of a century and a half. The eternal dispute about how it should be hung toilet paper (with the sheet “above” or “below” the roll) has generated conflicting opinions, family debates and even heated discussions. Those who prefer the “over” method give practical and hygienic reasons: it is easier to locate the end of the paper, it reduces the risk of contact with the wall (and therefore with germs) and it is visually tidier.

However, on the other side, supporters of “under” appeal to a more discreet appearance and the fact that, for example, it makes it difficult for pets or children to stay at home. unroll the entire paper.

An illustrated invention. However, all this controversy seems to have found an official answer in an unexpected place: a document from more than 130 years ago. In 2015, writer Owen Williams rescued an image history of Google Patents file which showed the patent registered in 1891 by Seth Wheeler, none other than the inventor of perforated toilet paper.

In it, it is clearly illustrated how the paper should be hung: above the roll (image below). The patent, registered by the Albany Perforated Wrapping Paper Company, includes unambiguous diagrams in which the paper is unrolled from the front.

Wheeler’s reasons. The inventor not only patented the concept of perforated paper in 1871, but two decades later, he perfected the roll design, with the intention of minimizing waste and facilitating its use without the need for complicated roll holders.

Your goal it was efficiencynot to fuel endless debates: “My improved roll can be used on the simplest supports”, wrote in the text of the patent. In its original conception, the paper should fall towards the front to facilitate individual tearing of the perforated sheets, thus avoiding accidental unrolling or unnecessary waste.

Science to the rescue. There is more data that corroborates that the “pro-encima” are right. Science also supports this orientation for purely health reasons. According to explained doctor Christian Moroprofessor of health sciences at Bond University, hanging the paper with the sheet on top reduces the risk of users touching the back wall of the holder when reaching for the end of the roll, which can minimize that spread of bacteria.

More remembered that among the potential contagion agents That can be found in bathrooms include streptococcus, staphylococcus, E. coli and common cold viruses, all capable of being transmitted through contact with contaminated surfaces. Preventing hands from coming into unnecessary contact with the wall or roll holder is therefore a simple but effective measure to reduce the risk of infection in shared spaces.

An invention… to review? Beyond the debate about how it should be placed, in recent years others have appeared around the invention. The New York Times explained in a column that although its invention represented at the time a technical improvement over previous methods (which included, attention, leaves, seashells, sticks with sponges or even reusable ceramics), the persistence of its use reveals less a functional effectiveness than a cultural resistance to abandoning the familiar.

Here the Covid-19 pandemic appears, when toilet paper acquired an unusual prominence: not for its medical usefulness, but as a symbol of control in the face of chaos. The mass hysteria led to emptying shelves, ignoring that neither the supply was threatened nor was paper the most hygienic solution. And despite this, experts agree that it is far from being the cleanest or healthiest option.

The evidence. The Times explained that researchers in infectious diseases and colorectal health agree that the exclusive use of paper does not guarantee adequate cleaning and can, in fact, cause irritation and promote the transmission of diseases. Among the pathogenic agents that can survive in poorly eliminated fecal remains are those germs and bacteria that we mentioned before and that cause urinary infections.

Traces of it were even detected coronavirus at the time in human feces. According to Dr. H. Randolph Bailey, a colorectal surgeon in Houston, many anal ailments he sees in his office come from excessive cleaning or with inappropriate products, such as wet wipes with perfumes and irritating chemicals.

Water as a solution. Here a parallel debate opens, surely more bitter. The reason? The most hygienic method, according to many specialists, is rinsing with water, either using bidets or similar. In Japan, for example, smart toilets with warm water jets are the normwhile in the West adoption remains marginal. The reasons are not technical or economic (today there are compact and accessible solutions), but rather cultural.

The rejection of the bidet has historically been associated with prejudice of modesty, licentiousness or even ridiculous misunderstandings like the one that occurred during World War IIwhen American soldiers learned about bidets in French brothels, which made them “suspicious” objects. The anecdote of a North American tourist who he mistook it for a bathtub for babies illustrates the extent to which discomfort in the face of the unknown has slowed its adoption, even in France, where it was originally common.

Or wipes. In recent times, a “plan C” has emerged against the fundamentalists from the roll or water: wet wipes. The problem is that it has been accompanied by environmental consequences. Its accumulation in sewer networks, combined with grease and waste, has led to enormous blockages (known in the world Anglo as “fatbergs“) capable of collapsing urban sanitation systems.

From that perspective, instead of improving the situation, wipes have added a new problem to an existing one, fueled by an industry that promotes brands with names like “Dude Wipes” either “Queen V”, appealing to the adult market with promises of freshness and modernity.

The weight of history. Be that as it may, and beyond personal preferences, toilet paper remains king in the bathroom, and the existence of an official document that supports the “above” orientation should settle one of the most trivial but persistent arguments in the domestic sphere.

At least from the inventor’s perspective, hanging toilet paper overhead was not only logical, but also functional. And although the context has changed, I would say that there is something comforting in knowing that even small everyday dilemmas have a historical root that can be solved with a simple sheet of paper… patented in 1891.
