About LayoutWise

LayoutWise makes free planning tools for home projects. Our goal is simple: help you buy the right amount of material the first time, and see how the finished job will look before you start.

What makes our tools different

• Visual plans. You see a to-scale layout with every cut, not just a number.
• Transparent math. Each tool explains its formula, assumptions and where the coverage figures come from.
• Tested. Every formula is checked against worked examples before it goes live.
• Private. Calculations run in your browser. We don't ask you to sign up.

How we source our numbers

Coverage rates for setting materials come from published manufacturer charts, and installation guidance follows industry standards such as ANSI A108. Where products vary, we use the conservative end of the range so you don't run short. Product labels and your installer's advice always take priority over general estimates.

Found a mistake?

Accuracy matters to us. If a result looks wrong, please tell us and we'll check it.
