Reporting an error
If a result looks wrong, please include:
- The page address (the Copy link button under each calculator copies it with your inputs).
- The result you got and the result you expected.
- Where your expected figure comes from, such as a bag label or a supplier’s spec sheet.
Confirmed errors are fixed, and the page’s “Updated” date changes when they are.
Suggesting a calculator
Tell us what you’re trying to work out and what you’d enter. Suggestions help decide what gets built next.
What we can’t help with
We can’t review plans, give engineering or legal advice or confirm that a project meets your local code. For those, contact a licensed
professional or your building department.
