Terms & Conditions
Last updated: 24 July 2026
By using Online Free Ruler, you agree to these terms. Please read them carefully. If you do not agree, please do not use the tool.
Use of the Tool
Online Free Ruler is provided free of charge for personal and commercial measuring tasks. You may use it in any modern web browser. You agree not to misuse the service, attempt to disrupt it, or use it for any unlawful purpose.
Measurement Accuracy
The ruler is designed to be accurate after calibration, but on-screen measurements depend on your display and how carefully you calibrate. We provide the tool as is and do not guarantee that measurements are exact. For critical work, verify with a certified physical measuring instrument.
No Warranty
The service is provided without warranties of any kind, express or implied, including fitness for a particular purpose. We do not warrant that the tool will be uninterrupted, error-free, or available at all times.
Limitation of Liability
To the maximum extent permitted by law, Online Free Ruler and its creators are not liable for any direct, indirect, or consequential damages arising from your use of, or inability to use, the tool — including any losses resulting from inaccurate measurements.
Intellectual Property
The Online Free Ruler name, design, and code are the property of their respective owners. You may use the tool for measuring, but you may not copy, resell, or redistribute the site as your own.
Changes to These Terms
We may update these terms at any time. Continued use of the tool after changes means you accept the revised terms. Questions can be sent to support@onlinefreeruler.com.
