Terms of Use

Last updated: September 2026.

General guidance only — not engineering, not a quote

BuildCalcs provides general construction math and rule-of-thumb guidance, compiled from published resources and manufacturer figures as of September 2026. It is not engineering advice, not a specification, and not a price quote. Structural decisions, code compliance, and anything with a stamped drawing belong to a qualified engineer and your local building department; material orders and contracts belong to a written local quote. Verify every number before you build or buy.
