Toilet Paper Dimensions

You might think that all toilet rolls have the same measurements since they’re considered a standardized item that looks the same no matter where you buy it. However, the size of toilet rolls can actually vary between manufacturers and different types available. In this article, we’ll explore the common dimensions of toilet paper rolls and the factors that can influence these size measurements.

Common Dimensions and Factors Affecting Size

Toilet Paper Roll Dimensions

Toilet Roll Length

The standard length of the cardboard tube inside a toilet roll is approximately 3.7 inches, although this can vary depending on the brand. Some toilet rolls have a length closer to 4 inches, which is equivalent to around 10 to 12cm. As the toilet paper on a roll covers the same surface area as the inner cardboard tube, the full roll’s length will also fall within this range.

Toilet Roll Diameter

The diameter of the inner cardboard tube of a toilet roll is typically around 1.6 inches or 4cm. To measure the diameter, simply hold a ruler across the center of the tube from one side to the other. When the toilet roll is brand new and no toilet paper has been used, the diameter will be larger. The measurement can vary depending on the toilet paper’s quality and thickness.

Different types of toilet paper (single-ply, double-ply, or triple-ply) can affect the final diameter of a full roll. Higher-end brands often have a wider diameter because they contain more paper or offer a luxury quality. Cheaper brands usually have a smaller diameter due to thinner toilet paper. Some fully loaded toilet rolls can have a diameter of up to 5 inches.


The term “ply” refers to the number of layers of paper in each sheet of a toilet roll. Single-ply toilet rolls have a single layer, while double-ply rolls have two layers, and triple-ply rolls have three layers. The layers are bonded together using lamination. Generally, the more layers there are, the thicker and more comfortable the toilet paper will be.

The ply affects the number of single sheets on a roll, but it does not necessarily determine how long a roll will last. A standard single-ply roll typically contains around 1000 sheets, while a double-ply roll contains 500 sheets (each sheet being double-layered). Despite containing fewer individual sheets, double or triple ply rolls are just as economical as single-ply rolls.

For example, if someone usually uses 12 sheets at a time with a single-ply roll, they will only need to use 6 sheets at a time with a double-ply roll to achieve the same thickness. With triple-ply rolls, there are approximately 333 sheets on each roll, but since you only need a third of the number of sheets per toilet visit compared to single-ply, the roll will last the same amount of time.

How Long Does a Toilet Roll Last?

How Long Does a Toilet Roll Last?

The duration of a single toilet roll depends on several factors. Firstly, individual usage varies, with people using different amounts of toilet paper on each visit. Secondly, the number of people using the toilet in your household affects how quickly a roll is depleted.

On average, a person uses between 10 and 20 sheets of single-ply toilet paper on each toilet visit. The average person visits the toilet four to five times a day, resulting in up to 100 sheets being used daily.

If you live alone, a single toilet roll can last you around 10 days. This calculation is based on a roll with 1000 sheets divided by using 100 sheets per day. However, if you have more people sharing the same roll, it will obviously be used up more quickly.

In a two-person household, a single roll should last at least five days. However, in a household with five people, a single roll will only last for one day. When estimating the lifespan of a roll, consider the ages and genders of the users as well. Research suggests that females tend to use more sheets per visit than males and may use the paper for additional purposes like makeup dabbing.

Children also tend to use the toilet more frequently and use more sheets each time, accelerating the consumption rate. Other factors such as someone in the household having a cold or allergies and using toilet paper when coughing or sneezing can also affect usage.
