Terms of Service

Plywood Calculator (the "Company") provides free online plywood calculators — a main sheet-count calculator (room dimensions, 4×8 ft and metric sheet sizes, thickness, material presets including softwood/hardwood plywood, MDF, and OSB, kerf and waste handling, along-length vs along-width comparison, and cost estimates) plus weight, fastener spacing, multi-room, edge banding, and cut optimization tools — on plywood-calculator.com (the "Website") for DIYers, contractors, cabinetmakers, woodworkers, students, and shop teachers. By accessing or using the Website in any way — running a calculation, reading a guide, or citing a result — you agree to comply with these Terms of Service. If you object to any term or condition here, or to any guideline posted on the Website, your sole and exclusive remedy is to immediately discontinue use of the Website.

We may revise, modify, or replace these Terms of Service at any time at our sole discretion. Changes take effect immediately upon posting to this page, and the latest version is always linked from the Website footer. Because the Website is free and requires no account, posting is deemed sufficient notice. You should review these Terms periodically — particularly before relying on calculator output for a real purchase order or a cut list.

All output from the Website — sheet counts with waste allowance, along-length vs along-width layout comparisons, kerf loss, cost estimates, panel weights, fastener counts and spacing, edge banding and seam tape lengths, and cut layouts with waste percentages — is provided for informational, planning, and educational purposes only. It is not a cut list, not an engineering drawing, not a manufacturer's certified specification, not a building-code compliance document, and not professional advice of any kind.

The Website does not replace a licensed contractor, a structural engineer, an architect, or the local building code and the authority having jurisdiction. Panel thickness and span ratings, actual sheet tolerances, framing conditions, wall openings, fastener schedules, and safe sheet handling are project-specific and must be evaluated for every build by qualified professionals. Nothing on this Website creates a professional relationship of any kind.

You agree not to post, transmit, or use the Website in any way that:

• Violates any applicable federal, state, provincial, or local law, including building codes where the project will be built
• Attempts to scrape, crawl, mirror, or bulk-download calculator results, sheet data tables, or guide content
• Reverse-engineers, decompiles, or extracts the calculation engines — sheet coverage, kerf loss, density × volume weight, fastener spacing, and cut optimization — for reuse in another product
• Misrepresents calculator output as a certified cut sheet, a professionally engineered panel layout, or a code-compliant fastener schedule
• Infringes any patent, trademark, trade secret, copyright, or other proprietary right of any party
• Uses forged headers, rotating proxies, or false identifiers to disguise the origin of requests to the Website
• Disrupts, overloads, or interferes with the normal operation of the Website or its infrastructure

Unless you receive explicit written permission from the Company, you may not copy, reproduce, resell, or exploit any part of the Website for commercial purposes. Quoting a short result with attribution and a link in a forum post, lesson, or project plan is welcomed; systematic republication is not.

The Website's software, calculation engines, original text, page designs, logos, and graphics are owned by the Company and protected by copyright and other intellectual-property laws.

Panel manufacturer names, APA standards, the IRC, sheet dimensions, thickness and density values, and technical documents referenced on the Website belong to their respective publishers. The Website independently implements publicly documented calculation methods — sheet coverage with waste and kerf loss, density × volume for panel weight, and fastener spacing per IRC Table R602.3(1) and similar published standards — and refers to those publications for identification and educational purposes only. This Website is not affiliated with, endorsed by, or sponsored by APA, the ICC, any panel manufacturer, or any standards body, and calculator output is not a substitute for the manufacturer's certified product data sheet, the current editions of the referenced standards, or the judgment of your contractor or engineer. Where precise product data matters, consult the manufacturer's published data and the authority having jurisdiction.

Our Privacy Policy explains how the Company collects, uses, and discloses information, and is incorporated into these Terms by reference. In short: the inputs you enter — room dimensions, sheet size, thickness, material, kerf width, waste factor — are processed locally in your browser and are not transmitted to or stored on our servers. Use of the Website constitutes acceptance of the Privacy Policy as well as these Terms.

The Website contains references to panel sizes, thicknesses, densities, span ratings, fastener schedules, brands, and third-party resources. These references are provided to help you find authoritative sources and are not intended to imply sponsorship, endorsement, or affiliation, or that any trade name, trademark, or logo may be used by you.

Calculator output may be affected by input accuracy, thickness and density variance between manufacturers, actual vs. nominal sheet dimensions, kerf width depending on your saw blade, walls out of square, door and window openings, framing obstructions, and reusable offcuts that the tool does not model. If you believe a formula, sheet data value, or guide statement is incorrect, contact us with the page URL, your inputs, and the result you expected — we investigate every report and update content to the extent the authoritative sources allow.

The Website is funded by third-party advertising, including Google AdSense. Ads are clearly distinguished from calculator output and editorial content. We do not control, endorse, or warrant advertised products or services, and any dealings between you and an advertiser are solely between you and that advertiser. Advertising cookies and your opt-out choices are described in the Privacy Policy.

The Company may set limitations on your use of the Website, and may modify, suspend, or discontinue the Website — or any part of it — at any time, with or without notice, at its sole discretion.

THE WEBSITE AND ALL CALCULATORS, SHEET DATA TABLES, REFERENCE VALUES, AND GUIDES ARE PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF ACCURACY, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT. YOUR USE IS ENTIRELY AT YOUR OWN RISK.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT SHALL THE COMPANY BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, OR CONSEQUENTIAL DAMAGES ARISING FROM YOUR USE OF (OR INABILITY TO USE) THE WEBSITE — INCLUDING DAMAGES FROM WRONG SHEET COUNTS, MIS-SPECIFIED THICKNESS, EDGE BANDING SHORTAGES, FASTENER SCHEDULE ERRORS, COST OVERRUNS, WEIGHT/HANDLING INJURIES, BUILDING CODE VIOLATIONS, EXCESS MATERIAL WASTE, PERSONAL INJURY, LOST PROFITS, OR ERRORS IN KERF LOSS, PANEL DENSITY, OR LAYOUT COMPARISONS. SOME JURISDICTIONS DO NOT ALLOW CERTAIN WARRANTY EXCLUSIONS OR LIABILITY LIMITATIONS, SO SOME OF THE ABOVE MAY NOT APPLY TO YOU.

These Terms of Service shall be governed by the laws of the United States, without regard to conflict-of-laws provisions. You and the Company agree to submit to the personal and exclusive jurisdiction of the courts located within the United States for any dispute arising from these Terms or your use of the Website.

If any provision of these Terms is held invalid or unenforceable by a court of competent jurisdiction, that holding shall not affect the validity or enforceability of the remaining provisions, which continue in full force. The Company's failure to enforce any right or provision shall not constitute a waiver of that right or provision, or of any further rights. These Terms, together with the Privacy Policy and the Disclaimer, constitute the entire agreement between you and the Company regarding the Website and supersede any prior agreements.

If you have questions about these Terms of Service, or need to report a violation of them, reach us via the contact page. We read every message and respond to legitimate inquiries.
