The spread of COVID-19 coronavirus has made life uncertain in many ways. But one thing is for sure, we’ve never been more aware of how much loo roll we have in the house.

As cities around the world have gone into lockdown to prevent the spread, people have turned to panic-buying. Top of their shopping list: toilet rolls.

Supermarket shelves have been emptied. Corner shops have been pillaged. Frantic WhatsApps have been sent the minute bog roll has been spotted out in the wild. But you can chill (seriously –please stop with the hoarding), because a clever new tool is here to reveal just how long you’ve got until you’re in risky pooping territory.

Based on these two toilet facts – an average healthy human produces around 400 grams of poop every day and uses one toilet paper roll every 12 days – the Poop Tool works out how long the rolls you’ve got will last your household.

Have 12 rolls in your bathroom cupboard? That’s enough for a two-person household to cope with 58 kg of poop, meaning it’s 72 whole days until you’re in the shit. That’s plenty of time for the shops to restock.
