How much toilet paper do you need to get through the coronavirus crisis?
A website created by student software developers Ben Sassoon and artist Sam Harris is helping people answer that question.
Howmuchtoiletpaper.com is a tool to calculate how long your stash of TP will last during quarantine.
The layout is simple. Users enter how many rolls of toilet paper they have and how many times they visit the loo.
If you scroll to the "Advanced Options" section, you can really get detailed, customizing the average number of wipes per trip, the number of sheets per wipe, sheets on the roll, and people in the house.
More than 2 million people have used the tool, the website says, and the average user has a whopping 500% more toilet paper than they need for quarantine.
The whole point of the tool is to reduce the toilet paper shortage around the world, which has begun as folks panic-buy rolls out of fear of the ongoing coronavirus pandemic.
"Not everyone is able to get to a store and stock up on toilet roll. Don't be selfish," the website says bluntly.
