Terms & Disclaimer
Disclaimer
Results are estimates. Verify measurements and local code before cutting.
FramersMath calculators are layout aids for general information. They are not engineering, architectural or code-compliance advice. Where a calculator references a code table (such as the deck joist spans), it reproduces a simplified prescriptive table and is not a structural design. They do not check structural adequacy, loads, fastening, or the requirements of your local building code, which may differ from the model codes (such as the IRC) mentioned on this Site.
Check all math and verify every result with a licensed engineer and your local building department before cutting or building. You are responsible for checking every measurement and for following your approved plans, the manufacturer's instructions and your local building department. Consult a licensed professional for structural work.
