What this site is for
Wall Math turns room measurements into purchase quantities for interior paint, wallpaper and flooring. A calculation is useful only when its inputs, boundaries and unknowns stay visible, so every result shows the assumptions it used.
Who operates this site
Wall Math is an independent material-planning website operated by MinSoo Kim, based in South Korea, for readers in the United States. Contact: thoopring@gmail.com.
How the site is reviewed
The tools estimate purchase quantities from the measurements and product information you enter. I maintain the calculations and review the explanations and their sources before a page is published; software helps with research and drafting, but no claim goes live without that review. Coverage and allowance figures in examples are examples only; the label of the product you buy is the source of truth. The tools do not replace product instructions or an installer’s assessment.
