Disclaimer of Warranties
The calculations and estimates provided by Drywall Calculator are for informational and planning purposes only. This service is provided "as is" and "as available" without warranties of any kind, either express or implied.
Specifically, we do not warrant that:
- Calculator results will be accurate, complete, or suitable for your specific project
- The service will meet your particular requirements
- The service will be uninterrupted, timely, secure, or error-free
- Results obtained from using the service will be reliable
This calculator does not provide professional, engineering, or contractor advice. Calculator results should not be used as a substitute for consultation with qualified professionals. For construction projects, fire-rated assemblies, structural modifications, or commercial work, always consult with licensed contractors and verify compliance with local building codes.
Limitation of Liability
To the fullest extent permitted by applicable law, Drywall Calculator and its operators shall not be liable for any indirect, incidental, special, consequential, or punitive damages resulting from:
- Your use of or inability to use the service
- Any decisions made or actions taken based on calculator results
- Material shortages, excess materials, or cost overruns on your project
- Errors or omissions in calculator outputs
- Any third-party content or conduct
You expressly understand and agree that you use this service at your sole risk. The calculator provides estimates only; actual material requirements depend on factors including room complexity, installer skill, material waste, and local conditions that cannot be predicted by any calculator.
Accuracy
We strive to provide accurate calculations based on established formulas and industry-standard coverage rates. Our methodology is documented on the About page. However, we do not guarantee the accuracy of any results.
Factors that may cause actual requirements to differ from estimates include:
- Room shapes and architectural features not captured by simple measurements
- Varying waste rates based on installer experience
- Material variations between manufacturers
- Regional differences in pricing and product availability
- Changes in material costs over time
Always verify calculations independently and purchase materials with appropriate contingency for your project's complexity.

Intellectual Property
The website design, user interface, graphics, logos, and original content are protected by copyright and other intellectual property rights. The underlying calculator code and article text are proprietary.
However, we acknowledge that mathematical formulas and general construction principles are not proprietary. The formulas used for calculating area, material quantities, and coverage rates are based on publicly available industry standards and are not claimed as exclusive intellectual property.
External Links
Our website and articles contain links to third-party websites, products, or services. These include industry standards organizations (such as the Gypsum Association, ASTM International, and ICC), government agencies (OSHA, EPA, FEMA, BLS), drywall manufacturers (USG, National Gypsum, CertainTeed, Georgia-Pacific), major retailers (Home Depot, Lowe's), and other authoritative sources.

Modifications to Service and Terms
We reserve the right to modify, suspend, or discontinue any aspect of the service at any time without notice. We may also update these Terms of Service periodically. Changes become effective upon posting to this page.
We will update the "Last Updated" date when changes are made. Your continued use of the service after changes are posted constitutes acceptance of the revised terms.
Termination
We reserve the right to restrict or terminate access to the service for any user who violates these terms or engages in conduct that we determine, in our sole discretion, to be harmful to the service or other users.
Since no account is required, "termination" would typically involve blocking access from specific IP addresses or networks engaged in abusive behavior.
Severability
If any provision of these Terms of Service is found to be unenforceable or invalid by a court of competent jurisdiction, that provision shall be limited or eliminated to the minimum extent necessary, and the remaining provisions shall remain in full force and effect.
