Use of the site

GirthCalculator.com provides free calculators for parcel shipping and body measurement contexts. You may use the site without registration. By using it, you agree to these terms.

No warranty

The calculators and reference information are provided "as is" without warranty of any kind. While we make reasonable efforts to keep carrier limits and body measurement formulas accurate, you are responsible for verifying any value against authoritative sources before relying on it for shipping decisions or health decisions.

Not medical advice

Body fat estimates, waist-to-hip ratios, and proportional targets are educational tools, not medical advice. Consult a qualified healthcare provider before making decisions about your health based on any value calculated on this site.

Not shipping advice

Carrier size limits change. Always verify against the carrier's current rate guide before shipping high-value items. We are not liable for surcharges, returns, or losses arising from outdated limit data.

Site content, design, and code are © GirthCalculator.com 2026. You may quote brief excerpts with attribution. You may not republish the calculators themselves or substantial portions of the content without written permission.

To the maximum extent permitted by law, GirthCalculator.com and its operators are not liable for any indirect, incidental, or consequential damages arising from use of the site.
