Terms of Use

Last updated: July 2026

Acceptance of these terms

By using Sizeaholic.com, you agree to these terms, our Privacy Policy, and our Disclaimer. If you don't agree, please don't use the site. We'll miss you, but that's how terms work.

Use of the site

Sizeaholic's calculators are free for personal and educational use through this website. You agree not to: use automated tools to scrape, copy, or republish our content or calculators (embedding through the snippets we provide is welcome, see below); attempt to disrupt or overload the site; or misrepresent Sizeaholic results as guaranteed professional or medical advice. All results are informational estimates, as described in our Disclaimer.

Free embedding license

You may embed any Sizeaholic calculator on your own website, free of charge, using the embed code we provide on each calculator page or on our embedding page. The license is simple: use the snippet as provided, keep the attribution link intact, and do not present the calculator as your own work or place it on pages that would misrepresent what it does. We may update how embeds work or discontinue them; the snippet always serves the current version. Embedded calculators keep the same privacy design as this site: nothing a visitor types is stored or transmitted.

Intellectual property

The Sizeaholic name, site design, calculator implementations, and written content are the property of the Calcaholic project. The underlying math is, of course, math. Nobody owns that, and our pages happily show it to you.

No warranty; limitation of liability

The site and its calculators are provided "as is" without warranties of any kind. As detailed in our Disclaimer, results are educational estimates drawn from population research, not medical advice. To the maximum extent permitted by law, Sizeaholic.com shall not be liable for any damages arising from use of the site or its calculators, including decisions made based on calculator results.

Third-party links

Pages may link to third-party sites, including the published research we cite and Amazon search results (as an Amazon Associate we earn from qualifying purchases). Those sites have their own terms and policies, which we don't control.

Changes to these terms

We may update these terms from time to time. The "last updated" date above reflects the current version, and continued use of the site after changes means you accept them.
