Terms of Service

Last updated: September 30, 2026

By using Real Online Ruler (the “Site”), you agree to these terms. If you don't agree, please don't use the Site.

The service

The Site provides a free on-screen ruler and related measuring tools. Use of the Site is free, requires no account, and is provided on an “as is” basis.

Accuracy

On-screen measurements depend on your display's calibration. The Site provides calibration tools, but we cannot guarantee that measurements match a physical ruler to any particular tolerance. Do not rely on the Site for measurements where an error could cause harm — medical, engineering, safety, or legal decisions. For critical work, always verify with a physical measuring instrument.

Acceptable use

You agree not to misuse the Site: don't attempt to disrupt it, don't scrape it aggressively, and don't present the Site or its output as your own product. The design, text, and code are the work of FK Digital Media.

Intellectual property

The Site's original content, design, and code are owned by FK Digital Media. You may use the measuring tools freely for personal and commercial measurement tasks; you may not copy the Site's design or text wholesale to create a competing service.

No warranties

The Site is provided without warranties of any kind, express or implied, including accuracy, reliability, or fitness for a particular purpose.

Limitation of liability

To the maximum extent permitted by law, FK Digital Media is not liable for any loss or damage arising from your use of — or inability to use — the Site, including decisions made on the basis of on-screen measurements.

Changes

These terms may be updated from time to time; continued use of the Site after changes are posted constitutes acceptance of the new terms.
