Planning estimates
Quantities from InteriorCalcs are estimates to help you plan and shop. Actual needs vary with room shape, cutting skill, tile size variation and how a product is applied. Follow the manufacturer's instructions and your installer's advice; where they differ from a calculator, they take priority.
Liability
The calculators are provided free and as is. We test them carefully but cannot accept responsibility for over- or under-ordering, or for work done based on a result.
Using the content
Use the calculators for any personal or professional project. Please do not republish the pages or scrape the site in bulk.
