The Science of Toilet Paper Orientation

The good people of Engineering Degree have tackled one of the most pressing issues of our time: should toilet paper hang over or under?

Check out the infographic below for a scientific approach to toilet paper orientation. For instance, did you know that how you prefer your toilet paper may determine your personality? And that I am among the 20% of people who have flipped a roll around when it was facing (what we believe to be) the wrong direction?

Frankly, all this data makes my head spin a little โ€” especially the formulas…physics was my worst subject at school โ€” and almost has me longing for three seashells instead. (Three points for anyone who can guess what movie I’m referencing!)


P.S. โ€” According to commenter Peter, toilet paper should always hang over for sanitary reasons.
