About Moonlight Tools

Moonlight Tools is a small collection of free calculators for tile and flooring installation materials. Each calculator focuses on one product, explains the formula it uses, and shows a worked example so you can check the result yourself.

Where the data comes from

Coverage rates, bag sizes and thickness limits are taken from each manufacturer's published technical data sheet (TDS). Every product page names the document and the date we read it. Manufacturers update their products and documents, so always confirm against the label on the bag and the current TDS before you buy or install.

Independence

All calculations run locally in your browser. We do not ask you to sign up, and the numbers you type are not sent to our servers. See the privacy policy for details.
