How Long Does a Roll of Toilet Paper Last?

Toilet paper is something that people use almost every day. Having enough toilet paper available is easy enough, however, it’s a good idea to plan out how much toilet paper to get for a certain period of time. So, below is how long a roll of toilet paper lasts, so you know how much to get at once.

On average, 18 days for men and 23 days for women. An average roll of toilet paper contains 150 sheets/squares of toilet paper, and on average, a male uses 8.1 sheets when they defecate, and an average female uses 6.3 sheets. Also, on average, a person defecates once per day.

However, there is wide variation when exactly a person takes a poop. For example, it’s common for people to not poop for 3 days and then take multiple poops in a day. 

In this article, I will provide detailed info about how much toilet paper a person uses for a week, month, and year, as well as how much an average person spends on toilet paper in a year.

How Many Rolls of Toilet Paper Does an Average Person Use in a Month

Toilet paper is sold in single rolls, but it is often better to buy it in a pack. When using the bathroom, most people don’t give much thought  to exactly how much toilet paper is used. So, This is how many rolls of toilet paper an average person uses in a month.

On average, males use 1.4 rolls per month, and females use 1.25 rolls per month. A roll of toilet paper lasts one male 18 days, which is 60% of a month. Whereas a roll of toilet paper lasts a female 23 days or 75% of a month. 

However, there are also double rolls of toilet paper. These are thicker than regular toilet rolls. The number of sheets a double roll or a regular roll has is typically stated on the packaging. For example, it will say 150 sheets per roll or 350 sheets per roll.

Therefore, the numbers listed above are minimums based on the smallest-sized roll of toilet paper that is sold, which is also the regular size. If you get double rolls, then exactly how long it lasts can vary. And you’ll need to have your calculator handy.

The key number to keep in mind is the amount of sheets used per day, and the average number of poops per day a person takes on average. 

Based on the data from the University of Massachusetts, they found that, on average, a person takes 1 poop per day. It is also found in studies than men an women use on average:

  • For men: 8.1 sheets per poop
  • For women: 6.3 sheets per poop

Based on these numbers, here are some very helpful tables that show how many rolls a man or a woman uses per week, month, 3 months, 6 months, and per year. So, 

TimeframeNumber of rolls used/required (1 man)
1 week5% of a roll (roughly 1/3rd of a roll)
1 month1.4 rolls
3 months4.2 rolls
6 months8.4 rolls
1 year16.8 rolls
TimeframeNumber of rolls used/required (1 woman)
1 week1/3rd of a roll (31%)
1 month1 and ¼ rolls
3 monthsJust under 4 rolls
6 months8 rolls
1 year16 rolls

In a year, a male will use about 1 roll more than a woman. If you want to buy enough toilet paper for a whole year then you should get an 18-pack if you’re a male. Otherwise, get a few packs to make up 16.8 rolls. Whereas, if you’re a female, you should get 16 rolls. Doing so will cover you for all the poops you will do in a year. 

This can take a reasonable amount of space, and one year is a very long period of time. Therefore, a more reasonable amount of toilet paper to buy is 6 months’ worth. Which is 8 around 8 rolls. 

These are somewhat rough numbers. For example, women will tend to wipe each time they go pee. But, also most people are at a job during the day. Therefore, they will take about half their daily pees at work.
