Frequently asked questions
How many rolls does the average family use per year?
The average American household (2.5 people) uses about 250-350 rolls per year.
How long should a 24-pack last?
Divide annual roll count by 24. If you need 330 rolls/year, a 24-pack lasts about 26 days.
Are double rolls worth it?
Compare price per sheet, not price per roll. A double roll (400 sheets at $1.80) is 0.45¢/sheet vs single (200 sheets at $0.95) also 0.475¢/sheet.
Why did toilet paper sell out during COVID?
Panic buying + supply chain designed for commercial use, not residential use, created temporary shortages.
