Find Screen Size

About Us

Welcome to Find Screen Size — the fastest, most private way to check your screen size, viewport dimensions, and display information online. Our mission is simple: provide accurate, real-time screen measurement data without tracking, ads, or unnecessary complexity.

What We Do

Find Screen Size is a browser-based tool that instantly detects your display specifications. When you visit our website, JavaScript reads your browser viewport dimensions, physical screen resolution, device pixel ratio (DPR), dots per inch (DPI), aspect ratio, color depth, orientation, and more. All measurements update in real time as you resize your browser.

Beyond basic measurements, we offer interactive rulers for measuring elements on screen, unit conversion between pixels, inches, centimeters, and millimeters, and responsive breakpoint detection for Tailwind CSS breakpoints.

Privacy First

We believe screen size data is personal and should stay on your device. That is why all measurements happen locally in your browser. We do not send, store, or track your screen resolution, viewport dimensions, or any display information. Google Analytics provides basic anonymized usage statistics so we can improve the tool, but your screen data never leaves your computer.

Who It Is For

Our tool is designed for:

  • Web Developers debugging responsive layouts and checking viewport dimensions across devices
  • UI/UX Designers verifying design specs match actual display measurements
  • Frontend Engineers testing CSS media queries and breakpoint behavior
  • General Users who want to know their screen size in pixels, inches, cm, or mm
  • QA Testers validating cross-browser and cross-device display characteristics

Our Commitment

Find Screen Size is and will always remain free. We do not display ads, require signups, or sell user data. We are committed to maintaining a tool that respects your privacy while providing accurate, useful display information.

If you have feedback, suggestions, or questions, we would love to hear from you. Please contact us with your thoughts.
