Reporting a number that looks wrong

Corrections are our top priority. To help us check quickly, please include:

• The calculator page you were using.
• The measurements and options you entered.
• The result you expected and where it comes from — for example a product label, a manufacturer's coverage chart or a store's price.

What we can't help with

We can't give project-specific engineering or code advice, quote local prices or recommend contractors. For structural questions such as deck framing, footings or load-bearing walls, contact your local building department or a licensed professional.

Other messages

Suggestions for new calculators, accessibility problems and general questions are welcome at the same address.
