Terms and calculator disclaimer.

Last updated: May 27, 2026

Acceptance of these terms

By using RightSizeTools, you agree to these Terms and Disclaimer. If you do not agree, do not use the site or rely on calculator results.

Purpose of the site

RightSizeTools provides free calculators intended to help with early planning, rough estimating, comparison, and buying decisions. The calculators are designed to be practical and user-friendly, but they are still estimates.

Estimates only

Calculator results are approximate and may be affected by assumptions, default values, rounding, measurement accuracy, product differences, installation conditions, local requirements, and information entered by the user.

Do not treat calculator results as guaranteed, exact, complete, code-approved, manufacturer-approved, engineering-approved, or safety-approved.

No professional advice

RightSizeTools does not provide engineering advice, architectural advice, electrical advice, HVAC design, plumbing advice, structural design, towing approval, vehicle safety approval, building-code advice, legal advice, medical advice, financial advice, or other professional services.

Where a project or purchase involves safety, code compliance, equipment ratings, structural loads, electrical systems, fuel-burning appliances, towing, water management, insulation requirements, or other higher-risk decisions, consult qualified professionals and official product documentation.

Verify before buying, building, towing, or installing

Before buying materials or equipment, starting work, towing a load, sizing equipment, or relying on a result, verify the final decision using actual product specifications, manufacturer instructions, equipment labels, vehicle ratings, manuals, local code requirements, and site-specific conditions.

Running short on material, undersizing equipment, overloading a vehicle or trailer, using incorrect electrical equipment, or ignoring code/manufacturer requirements can create cost, performance, inspection, or safety problems.

User responsibility

You are responsible for the information you enter, the assumptions you choose, and any decisions made from calculator results. RightSizeTools is not responsible for incorrect inputs, misunderstood units, unsuitable assumptions, product differences, field conditions, or changes in applicable requirements.

No warranties

The site and calculators are provided on an “as is” and “as available” basis. RightSizeTools makes no warranties or guarantees that the site will be error-free, uninterrupted, complete, accurate, current, secure, or suitable for a specific project or use.

Limitation of liability

To the fullest extent permitted by law, RightSizeTools and its owners/operators are not liable for losses, damages, incorrect purchases, failed inspections, unsafe use, project delays, wasted materials, equipment problems, code issues, business losses, or other outcomes arising from use of the site or reliance on calculator results.

Third-party links and references

The site may include links to third-party websites, product pages, manufacturers, public resources, advertisers, affiliate partners, or other references. Those links are provided for convenience only. RightSizeTools does not control and is not responsible for third-party content, products, services, policies, pricing, or availability.

Advertising, affiliate links, and sponsorships

RightSizeTools may include advertising, affiliate links, sponsored placements, or referral links in the future. If affiliate links are used, the site may earn a commission from qualifying purchases or actions at no additional cost to the visitor. Advertising or affiliate relationships do not change the need to verify product suitability independently.

Intellectual property

The site design, calculator pages, written content, and other materials on RightSizeTools are owned by or licensed to the site operator unless otherwise noted. You may use the calculators for personal or business planning, but you may not copy, republish, scrape, sell, or redistribute substantial portions of the site without permission.

Acceptable use

Do not misuse the site, attempt to interfere with its operation, use automated systems to overload it, bypass security measures, or use the site in a way that violates applicable law or harms other users, the site, or third-party services.

Changes to the site

Calculators, formulas, assumptions, pages, categories, features, and policies may be updated, corrected, removed, or discontinued at any time without notice.

Changes to these terms

These Terms and Disclaimer may be updated as the site changes. The updated date at the top of the page will reflect the latest revision.
