Informational purposes only

The calculators and content on Blueprint Calc are provided for general informational and planning purposes only. They are not a substitute for advice from a licensed contractor, engineer, architect, building official, or other qualified professional. Always verify calculations, building codes, and safety requirements for your specific project and jurisdiction before buying materials, pouring concrete, framing a deck, or making any construction decision.

No warranty

The Site and the calculations it produces are provided "as is" and "as available," without any warranty of any kind, express or implied. We make no guarantee that the calculations are accurate, complete, up to date, or suited to any particular purpose. Industry constants (paint coverage, bag yields, joist spans, waste factors) reflect typical US residential practice as of the "Last updated" date; your materials, suppliers, and local code may differ.

To the maximum extent permitted by law, Blueprint Calc and its operators are not liable for any damages, losses, or expenses — including but not limited to over-purchased material, under-purchased material, structural failures, code violations, or personal injury — arising from your use of the Site or reliance on its output. Your use of the Site is at your own risk.

The Site contains affiliate links to Home Depot, Lowe's, Amazon, and other retail and lead-generation partners. When you buy through these links we may earn a commission, at no additional cost to you. See the affiliate disclosure for details.

All original content, code, calculator logic, and site design is copyright Blueprint Calc, all rights reserved. You may share links to specific calculators and quote short passages with attribution. You may not scrape the site, mirror it, or republish substantial content without written permission.

Changes to these terms

We may update these terms from time to time. Material changes will be reflected in the "Last updated" date above. Continued use of the Site after changes constitutes acceptance of the revised terms.
