Disclaimer

These calculators give estimates, not quotes. Results assume the inputs and material figures shown, and real jobs vary with site conditions, product choice and local code. Confirm quantities with your supplier and check your local building code before you buy or build.

What the numbers assume

Results depend on the measurements you enter and on the material figures shown on each page. Real products vary by manufacturer, mix, moisture and grade, and real sites are rarely perfectly square or level.

What to check before you buy or build

• Measure twice and confirm dimensions on site.
• Ask your supplier to confirm quantities and coverage for the exact product you are buying.
• Check your local building code and permit requirements. Code limits shown on this site are for reference and may differ from the version your area has adopted.
• Use a licensed engineer or contractor for structural work, such as beams, footings, retaining walls and roof framing.
