By using this Website, you represent and warrant that you are at least 13 years of age (or the minimum age required in your jurisdiction) or are accessing the Website under the supervision of a parent or legal guardian who agrees to be bound by these Terms.

When interacting with the Website, you agree not to:

3. Informational Purpose & Medical Disclaimer

Child growth trajectories and adult statures depend on complex biological and environmental factors including polygenic inheritance, nutritional history, endocrine system balance, and individual developmental tempos. Clinical algorithms such as the Khamis-Roche method and mid-parental formulas provide probabilistic mathematical models derived from sample reference cohorts—they are not clinical certainties or physiological guarantees.

Never disregard, delay, or substitute professional medical advice, consultation, or diagnosis from a qualified pediatrician, endocrinologist, or licensed healthcare provider based on information or calculations obtained from this Website.

4. Accuracy Disclaimers & Data Limitations

We strive to provide reliable algorithms, accurate unit conversions, and up-to-date demographic benchmarks based on credible sources (including the World Health Organization, CDC, and peer-reviewed pediatric literature). However:

• Celebrity and Entity Data: Statures of public figures and cultural entities in our comparison tool are collected from public records, official biographical listings, and media interviews. Known variations in reported heights can occur.
• Demographic Stature Data: Country-level average heights are drawn from epidemiological sample surveys (such as NCD-RisC and national health statistics) and represent population means, which naturally fluctuate across generations and demographic cohorts.
• No Guarantee of Uninterrupted Access: The Website and its features are provided on an "as is" and "as available" basis without warranties of any kind regarding continuous availability, mathematical infallibility, or uninterrupted functionality.

5. Intellectual Property Rights & Nominative Fair Use

All original software code, user interface components, SVG visualizer graphics, explanatory guides, and layout design on this website are protected by copyright, trademark, and other applicable intellectual property laws owned by or licensed to Online Height Calculator.

Names, likenesses, and statures of public figures, celebrities, athletes, historical personas, or cultural entities displayed in the comparison visualizer are referenced strictly under the doctrine of nominative fair use for identification, factual commentary, and proportional size comparison.
