Effective date: October 23, 2026
These Terms of Use apply when you access Stone Calculator at stonecalculator.vip. By using the site, you agree to use it in accordance with these terms and applicable law. “Stone Calculator” identifies this website and its published calculator and reference content; it does not identify a supplier, contractor, professional practice, or separate legal entity.
Purpose and scope
Stone Calculator is an online calculator and reference resource for natural-stone and slab work. Only tools and guides that appear in the live calculator directory or Guides archive are available. Site descriptions do not make an unpublished tool available.
Estimates are not professional decisions
Calculator outputs are estimates produced from the inputs and method shown on the applicable page. They are provided for informational and planning use. They are not a quote, purchase order, measurement service, fabrication or installation plan, structural design, engineering opinion, safety determination, code-compliance finding, warranty, or professional sign-off.
Results depend on the accuracy and completeness of your measurements, selected units, product specifications, and other inputs. A mathematically valid result may still be unsuitable for a particular stone, product, layout, site condition, or work method. Verify consequential results against current manufacturer and supplier information, drawings, templates, and the qualified professional responsible for the work. Do not use a calculator result as the sole basis for a safety-critical or regulated decision.
Your use of calculators
You are responsible for selecting a tool that matches the question, entering appropriate project and product data, reviewing its assumptions and limits, and independently checking important results. Input ranges and validation messages describe the tool’s accepted data; they are not recommendations or proof that an input is correct for your project. Do not submit confidential customer or personal information in calculator fields or feedback.
Permitted and prohibited use
You may use the public pages for lawful informational and estimating purposes. Do not attempt unauthorized access, interfere with site availability or security, send abusive or excessive automated requests, introduce malicious code, or use the site to violate another person’s rights or applicable law. We may restrict requests that threaten the service or its users.
Content, sources, and external sites
Content and software are provided as part of this website. Access does not transfer ownership or grant permission to republish substantial material, remove notices, or represent the material as your own. Applicable legal exceptions remain unaffected. External links are provided for reference; they lead to independent sites and do not imply that Stone Calculator controls, verifies, or endorses every statement or product on them. Check the source itself for its current terms and specifications.
Availability and changes
Pages, tools, methods, and external links may change, become unavailable, or be corrected. We may revise these terms as the site develops. The effective date above identifies the current version. Continued use after an update means the revised terms apply to later use, to the extent permitted by applicable law.
Limits of these terms
The site is provided without a promise that every page will be uninterrupted, error-free, complete, or suitable for a specific project. Nothing in these terms removes a consumer right or other protection that cannot lawfully be excluded. If a term cannot be applied under applicable law, the remaining terms continue to the extent they can operate independently.
