Math Behind a toilet paper: Length, width and lasts

In this post, we describe the math behind toilet paper and why it matters for your bathroom. We also discuss the length, width, and last of different types of toilet paper.

If you have ever wondered how the size of the toilet paper roll is determined, then you are probably not alone. The answer to this question is surprisingly simple. When you buy a toilet paper roll, you have the option of choosing between two different sizes: “long” or “short.” The choice of which one you choose depends on the size of the toilet you have and how much toilet paper you need to use. You may have noticed that the length of the toilet paper roll you use is longer than the rolls used in other countries. Why? Well, in most countries, toilet paper rolls are typically made from a material called tissue paper. Tissue paper is made from wood pulp, which is a natural product that has been refined and processed. In contrast, the toilet paper rolls you use in the United States are made from a man-made product known as cellulose fiber. Cellulose fiber is a manufactured product that is made from tree pulp. It is a more refined and processed version of the wood pulp that is found in toilet paper rolls made in other countries.

If you’re like most people, you probably think that a roll of toilet paper is the same as any other roll of toilet paper. But, if you want to be sure that you have enough toilet paper on hand, you should know exactly how much a roll is.

The length of a roll of tissue is three-and-a-half inches or 0.3 feet.

The average width of a roll of toilet paper is approximately 10 to 12 centimeters, which is about three and an eight-inch wide.

At first, it was four inches long, then it went down to 2.7 inches, and now it’s back to 3.1 inches again, with a chance of decreasing once more.

Other factors that affect the overall width of the roll also affect other roll paper functions, like the length of the roll paper.

Some of the factors that go into determining the number of sheets per roll include; Number of rolls in a pack The service length of the tissue paper The type of pallet and logistic unit The number of packs per bundle The core diameter All these elements come into play during the manufacturing of the toilet roll which then gives off different measurements.

A number of factors contribute to the general weight of a tissue paper.

The base paper is the first thing you need to think about when it comes to making a paper that can withstand multiple folding cycles.

All different colored and textured tools will also have an additional amount of weight.

The number of plies in tissue is not related to the thickness of the sheet.

How is ply bonded? Lamination, where the embossed ingredients are simply glued, vs using a mechanical edge emboss, has different results.

Now let’s get into maths a bit deeper and calculate. A toilet paper roll consists of  1000 sheets for a single ply and 500 for two-ply approximately, and so on for further plies. The number is not 100% certain with companies using the plus or minus sizing.

A person will use about 8 to 20 sheets per toilet use to equivalent an average of  60 sheets per day if we consider three uses of toilet per day.

The total amount of sheets per roll, assuming single ply, (1000) and divide by daily use (60)

will show us that it will last for 16 days  which is equal to two weeks and 2 days

This formula assumes all other elements are constant, such as you go to the toilet three times a day, the same number of sheets per visit, and one-ply tissue paper.

What Will Determine the Duration of toilet paper?

How many rolls of toilet paper do you have in your bathroom? If you’re like most people, you probably don’t have an exact count. The truth is, toilet paper has a very simple formula: 3 x length x width. And since you’re not buying a roll of toilet paper every day, the amount you have on hand is a fairly good indicator of how long your toilet paper will last. To calculate how many rolls you should buy, simply multiply 4 x length x width and divide by 365. That’s it! However to be more accurate it depends on a number of factors explained as under.
