These Terms & Conditions apply to your use of audiobookspeedcalculator.org (the “site”). By using the site you agree to them. If you do not agree, please do not use the site.
The site provides free tools and information for audiobook listeners, including the Audiobook Speed Calculator, the Libby Speed Calculator, the audiobook speed chart, an audiobook length list and listening guides. The site is free to use and does not require an account.
Calculator results are estimates for planning purposes. Actual listening time can differ because of how each app applies playback speed, chapter breaks, pauses and rounding.
Always check the details shown in your own audiobook app or library account.
You agree not to:
The site’s text, calculators, charts, design and images belong to Audiobook Speed Calculator or its licensors and are protected by copyright. You may link to any page and quote short passages with a link back to the source. Any other reuse needs our written permission.
Audible, Libby, OverDrive, Spotify, Apple Books, Hoopla, Scribd and other product names mentioned on the site are trademarks of their respective owners. We use them only to describe compatibility and features. The site is independent and is not affiliated with, endorsed by or sponsored by any of these companies.

The site and all tools are provided “as is” and “as available”, without warranties of any kind, express or implied, including accuracy, fitness for a particular purpose and uninterrupted availability. We may change, suspend or remove any part of the site at any time.
To the fullest extent permitted by law, Audiobook Speed Calculator is not liable for any indirect, incidental or consequential loss, or for any loss arising from reliance on calculator results or site content, such as a library loan expiring before you finish a book. Nothing in these terms limits liability that cannot be limited under applicable law.
We may update these Terms & Conditions from time to time. The new version will be posted on this page with an updated “Last updated” date. Continuing to use the site after a change means you accept the updated terms.
If any part of these terms is found to be unenforceable, the rest of the terms remain in full effect.
