Terms

Lumber Calc is free to use for planning and estimating. You may use the results to plan your own work and to share a link to the inputs you entered.

Results can be wrong. They are not a structural design, a code official’s ruling, or a product specification. You are responsible for checking them against the material in front of you and the code adopted where you build.

Do not present a result as an inspection, an engineering stamp, or an endorsement by a lumber retailer or decking brand. Lumber Calc is not affiliated with those companies. Google AdSense may show ads on these pages. Affiliate links, when present, may earn a commission at no extra cost to you.

The calculators and these terms can change as formulas, codes, and pages are corrected. The page you are reading is the current set of terms. Questions: hello@lumber-calc.com.
