What Tallyard provides
Tallyard publishes free online calculators and editorial guides related to home improvement, construction, and DIY projects. These tools provide material estimates and informational content for planning purposes.
Not professional advice
Tallyard calculators produce estimates, not engineering specifications, construction documents, or professional advice. Results depend on your inputs and on assumptions that may not match your specific project conditions. For structural work, electrical wiring, plumbing, permitting, or anything where safety is at stake, consult a licensed professional. Tallyard is not a substitute for a contractor, engineer, architect, or building inspector.
Accuracy and limitations
We make every reasonable effort to ensure calculators produce accurate estimates based on current manufacturer specifications and industry standards. However, material costs, coverage rates, and building code requirements vary by region and change over time. Always verify quantities against your actual material specifications before purchasing. Always verify code requirements with your local building authority before beginning work.
Limitation of liability
Tallyard is provided “as is” without warranty of any kind, express or implied. Tallyard, its founder, and its contributors are not liable for material shortages, overages, project cost overruns, structural failures, or any other outcomes resulting from use of calculator results or guide recommendations. Use at your own risk and judgment.
Intellectual property
Content on this site, including calculator code, guide text, visual design, and illustrations, is the property of Tallyard. You may share links to any page. You may not reproduce substantial portions of guide content without permission. Calculator formulas themselves (the math) are not proprietary; our specific implementations and explanations are.
External links
Tallyard may link to external sites (manufacturer pages, government resources, code references) for sourcing purposes. We do not control and are not responsible for the content, availability, or privacy practices of external sites.
Changes to terms
We may update these terms. Material changes will be reflected in the “last updated” date above. Continued use of the site after changes constitutes acceptance of updated terms.
