Terms of Service

These terms cover using vehicleinterior.com: the six calculators, the blog, the learn section, and the museum. Using the site means you agree to them.

What VehicleInterior Is

VehicleInterior is an independent, ad-supported reference site about car interior design and upholstery — fabric and trim, seat foam and comfort, carpet, window tint, and interior customization. It is not a trim shop, installer, or materials retailer, not affiliated with any brand or manufacturer, and not a professional automotive service. The Upholstery Fabric Calculator, Carpet Area Calculator, Seat Foam Calculator, Window Tint VLT Calculator, Cargo Volume Calculator, and Material Cost Estimator are free, browser-based tools built on standard formulas and the numbers you enter.

Using the Tools

No account, sign-up, or payment is required to use any calculator. Inputs you type into a tool are processed in your browser to produce an estimate; see the Privacy Policyfor what does and doesn’t leave your device. Results are general guidance based on standard formulas and rules of thumb, not a validated specification for your specific vehicle, materials, or local regulations.

Not Professional or Legal Advice

Nothing on VehicleInterior is professional automotive, installation, or legal advice. Material quantities depend on your actual panels, cutting layout, and waste; comfort and durability depend on the specific foam and trim; and window-tint legality depends on local law, which varies by country and by state and changes over time. For anything binding — a tint that must be road-legal, a modification that affects safety — confirm with a qualified installer, the product manufacturer, or your local authority before you rely on a calculator result. The full reasoning is in the Disclaimer.

Acceptable Use

When using the site, you agree not to:

• Automate requests against the tools at a volume that degrades the site for other visitors
• Scrape, republish, or resell the site’s content or tool logic wholesale
• Attempt to bypass, disrupt, or probe the site’s security
• Submit deliberately false information through the contact or subscribe forms
• Use the site for any unlawful purpose

Content & Ownership

VehicleInterior’s own text, calculator design, and site design belong to VehicleInterior. The museum and learn sections draw their entries, images, and facts from Wikipedia and Wikimedia Commons, used under their respective public-domain and Creative Commons licenses — that content belongs to its original contributors, not to VehicleInterior.

Ads & Affiliate Links

The site carries Google AdSense advertising and, on some tool and article pages, Amazon affiliate links. Both are disclosed in full in the Affiliate Disclosure. Ads and product links are served by third parties and are not endorsements by VehicleInterior.

No Warranty

The site, its tools, and its content are provided “as is,” without warranties of any kind, express or implied, including accuracy, fitness for a particular purpose, or uninterrupted availability. We try to keep the calculators correct and the guides current, but we don’t guarantee either.

Limitation of Liability

To the extent permitted by law, VehicleInterior isn’t liable for damages arising from your use of, or inability to use, the site or its tools, including decisions made based on a calculator result or an article.

Changes to These Terms

These Terms may be updated from time to time; the date above reflects the most recent revision. Continuing to use the site after a change means you accept the updated Terms.

Governing Law

These Terms are governed by the laws of the United States, without regard to conflict-of-laws principles.
