Terms & Conditions

1. About Online Ruler

Online Ruler provides digital on-screen measuring instruments that allow users to utilize their device displays as physical rulers to measure, compare, or estimate object dimensions across various metric and imperial units:

• Centimeters (cm)
• Millimeters (mm)
• Inches (in)
• Screen Pixels (px)

Website features, user interfaces, available units, and functionalities may be modified, updated, or temporarily suspended at any time without prior notice.

2. Permitted Use

You are permitted to use Online Ruler for personal, educational, engineering reference, web design, crafting, and general everyday measuring purposes in full compliance with applicable laws.

You expressly agree not to:

• Use the website for any unlawful, fraudulent, or harmful purposes
• Attempt to compromise, disrupt, reverse engineer, or degrade server infrastructure or client software
• Gain unauthorized access to non-public endpoints, servers, or networks connected to the service
• Deploy bots, spiders, scrapers, or automated tools that impose an unreasonable load on the service
• Reproduce, duplicate, resell, or distribute website assets in violation of applicable copyright protections
• Utilize the website to deceive, misrepresent measurements commercially, or infringe upon the rights of others

3. Measurement Accuracy & Limitations

Online Ruler calculates scale markings using device screen dimensions, hardware resolution, reported pixel density, and custom calibration factors. Measurement results may be influenced by:

• Physical hardware screen size and display aspect ratio
• Operating system display scaling (DPI scaling, Retina multipliers)
• Web browser zoom levels (which must remain at 100% for physical scale parity)
• Selected calibration method and reference object fidelity
• Physical positioning, angle, and parallax of the item placed against the screen

To achieve accurate 1:1 real-world physical correspondence, users must perform manual calibration using a standardized physical card (such as a standard bank card or ID card). Online Ruler does not warrant that on-screen measurements will achieve the absolute precision of lab-certified micrometers, calipers, or official survey instruments.

4. Screen Calibration Responsibility

Users are solely responsible for ensuring calibration is performed accurately. When using a credit card, bank card, or driver's license (standard ISO/IEC 7810 ID-1 specification measuring 85.60 mm in width), ensure the physical card is aligned precisely with the calibration guide slider. Automatic hardware presets serve as helpful initial estimates but may vary across individual display panels.

5Service Availability & Modifications

While we strive to ensure continuous 24/7 global availability, we do not guarantee uninterrupted, bug-free, or error-free site operation. The service may encounter intermittent downtime due to:

• Scheduled maintenance and infrastructure upgrades
• Network routing issues, DNS propagation delays, or cloud outages
• Unannounced upstream browser engine updates modifying CSS pixel rendering
• Circumstances and force majeure events beyond our reasonable control

6Intellectual Property Rights

All website components, source code, interactive ruler components, styling, typography, graphics, icons, logos, and written documentation are the proprietary intellectual property of Online Ruler or used under valid license. You may not copy, extract, replicate, recompile, or commercially exploit any software algorithms or assets without explicit prior written authorization.

7External Content & Third-Party Links

Online Ruler may provide hyperlinks to third-party web portals or documentation. We do not control and accept no responsibility for the editorial content, accuracy, safety, or policies of external websites. Following external links is conducted solely at your own discretion and risk.

9Limitation of Liability

To the fullest extent permitted by applicable law, Online Ruler, its developers, and affiliates shall not be liable for any direct, indirect, incidental, punitive, or consequential damages resulting from:

• Use of or inability to use the online measuring software
• Reliance on measurements for structural, commercial, medical, or architectural tasks
• Errors stemming from improper calibration, screen distortion, or incorrect zoom ratios
• Service disruptions, unexpected downtime, or loss of cached preferences
• Any financial or material damages arising out of manufacturing or purchasing decisions based on digital ruler readings

Users must independently verify critical dimensions using certified physical measuring tools whenever millimeter precision is crucial for safety, commerce, construction, or technical manufacturing.

10Changes to These Terms

We reserve the right to revise or update these Terms & Conditions at our discretion. Updated terms take effect immediately upon being posted on this URL. Your continued use of the website following changes constitutes binding acceptance of the updated terms.
