What the results are

Every figure produced here is an estimate based on the measurements and assumptions you supply. Real projects vary with the specific product, the installation method, the manufacturer instructions, site conditions, local regulations and the accuracy of your own measuring.

What the results are not

They are not engineering approval, not a code compliance check, and not a professional design. Structural, electrical, gas and load-bearing questions are outside the scope of this site and should go to a qualified professional.

Check before you buy

Confirm coverage, yield and dimensions against the actual product you intend to buy. Package coverage and bag yield differ between manufacturers, and a calculator can only be as accurate as the figures you give it.

Availability

The site is provided as it is, without a guarantee of uninterrupted availability. Calculators run in your browser, so they keep working even when optional third-party scripts fail or are blocked.

Liability

Purchasing decisions remain yours. Verify quantities against your own measurements and your supplier's specifications before ordering material.
