Toilet paper is the most widely used item in households and even in public bathrooms. You might wonder why we are talking about this topic. Or is it that much important to know about the toilet paper roll circumference? So the answer is yes, it is important to know about it. And what are the various factors that need to be kept in mind while selecting a toilet paper roll? Also what factors do the toilet paper roll manufacturers consider while making it?

In this article, we will see the circumference of the toilet paper roll that is being used in your day-to-day life along with the factors to be considered while choosing a toilet paper roll for your home or workplace, etc.

So, as it is already clear that a toilet paper roll is circular and for a circular shape we find the circumference in place of the parameter. Now we need to know about the circumference.

Before that let us see the other dimensions of the toilet paper roll from the inside

### What is the length of the cardboard tube used inside the toilet paper roll?

The cardboard tube used inside the toilet roll should be 4 inches in length.

### What is the width of the toilet paper roll from inside?

The width can be determined by subtracting the total Width from the width of the cardboard tube. That will be approximately **12 inches – 4 inches = 8 inches**.

### What is the diameter and radius of the toilet paper roll?

To find the circumference it is highly important to know the diameter or radius of the toilet paper roll. The diameter is approximately 6 to 8 inches whereas the radius will be 3 to 4 inches.

## What is the circumference?

Circumference is a one-dimensional linear figure measurement of any shape. It is the total distance around the circle or any type of geometrical figure.

So basically the mathematical formula for measuring the circumference of any circular figure is **circumference = 2πr**. Where π is the constant with a constant value of **3.14 or 22/7**. And r is the radius of the circle.

Here is one more formula that can be used if the diameter of the circle is known instead of the radius. that is **circumference = πd** where d is the diameter and π is again the same.

Calculations calculations calculations!

**Circumference = 2πr = 2 × 3.14 × 3.5 = 22 approx. inches**

**Or,**

**Circumference = πd = 3.14 × 7 = 22 approx inches**

### Why is it important to calculate the circumference of the toilet paper roll?

Circumference affects how much toilet paper is being dispensed from the roll at once. So that you can use it efficiently to reduce wastage.

### What is the total length of the toilet paper roll?

The total length of the toilet paper roll can be measured by adding all the layers of the toilet paper. For that, we need to know the total turns of the paper wrapped around the cardboard roll.

### Total Length of the roll = no. Of turns × length of one turn

But the no. Of turns may vary depending on the type and brand of the toilet paper. The average turns can be 100 to 200 let us take as 100 turns per roll then the total length will be

**100 × 37.68 inches = 3768 inches**

**or 314 feet.**

## What are the various factors on which the circumference of the toilet paper roll depends?

Dimensions, thickness, no. Of plies, texture, and size of the toilet paper. These are the factors that are considered by anyone before buying a toilet paper roll and also by the manufacturers before making them. Let us see how they affect the circumference of the toilet paper roll.

### Dimensions of the roll

dimensions such as length, width, and depth of the toilet paper roll are crucial factors because they are the factors that decide the overall structure of it. The height is usually between 16 to 18 inches. Whereas the Width is 14 to 16 inches and lastly the depth is always taken as 12 inches from the front to the back of the roll.

### Thickness

Thickness of the numbers or turns that are wrapped around the cardboard roll. The more the turns, the more the thickness will be and the more paper you will get. Thickness varies according to the brand and type of toilet paper. There are various types and sizes of rolls available in the market such as normal, medium, or jumbo-size rolls.

### No. Of plies

The number of plies is nothing but the layers of paper that are wrapped on the roll. More the layers of toilet paper stronger it will be and hence will be much more durable as compared to the ones having less numbers of plys. In the market there are various varieties are toilet paper rolls available such as single-ply, double-ply, triple or quadruple-ply, etc. Their price and durability vary accordingly.

### Texture

In the case of texture also you can get various varieties. The texture of the toilet paper determines how soft or rough it feels like in touch. And the texture of the toilet paper depends on the material of the paper. Recycled material is always hard and rough in texture as compared to the Virgin one. Also, paper from a hardwood tree will make rough paper whereas from the soft wood will make soft paper.

### Size

Various sizes are available such as small, medium, and jumbo sizes. Small and medium ones are convenient for household purposes and for places where there is less consumption needed but if you are seeing it for public places such as public restrooms, malls, offices, etc then go for jumbo size without hesitation.

### How Does the Size of a Toilet Paper Roll Affect its Performance?

The size of the toilet paper roll has a great impact on its performance. It is one of the most important factors to be considered for the overall design of your bathroom. The number of sheets or the turns decides how often you need to refill it when it gets finished. So it depends on the user if you need an efficient roll or not.

You might also want toilet paper to be a bit long enough to protect both of your hands and also itself from dropping and hanging to the floor.

### What is the average thickness of the toilet paper roll?
