About What Is My Screen Resolution

Informational only, not professional advice. Report an error.

Screen resolution questions come up when you crop screenshots, pick UI breakpoints, or check whether a display is running at the size you expect.

This tool reports CSS pixels from the screen APIs, an approximate physical pixel size using device pixel ratio, available area, and color depth. High-DPI laptops often show CSS sizes smaller than the marketing resolution on the box.

Pair with What Is My Device when you want phone versus desktop class alongside the pixel numbers.

Common use cases

  • Solve quick everyday math or timing tasks without installing an app.
  • Double-check unit conversions for recipes, travel, fitness, or homework.
  • Count days between dates for planning, deadlines, or simple schedules.
  • Generate random numbers or run a browser timer for games, meetings, or focus blocks.
  • Use What Is My Device when your next step needs a related calculation on the same page tab.

How to use What Is My Screen Resolution

  2. Paste or enter input. Add the text, numbers, or dates you want to transform.
  3. Review output. Check the result panel. Errors usually point to the line or field that needs fixing.

Common mistakes and fixes

  • Pasting API keys or secrets, tokens, or personal data into any browser tool.

    Fix: Use redacted samples in development. Client-side processing still leaves data in browser memory and history.

  • Mixing date-only and datetime fields when the UI expects calendar dates.

    Fix: Match the input style shown on the tool. Date-only mode counts calendar days, not clock times.

  • Picking the wrong unit category (weight versus volume, miles versus km).

    Fix: Confirm unit labels on the tool match the values you entered before you copy the result.

FAQ

Why do CSS pixels differ from my monitor box label?
Browsers report CSS pixels. Physical pixels multiply by device pixel ratio on Retina and other high-DPI screens.
Does window size affect the result?
Screen size comes from the display APIs, not the browser window size. Available area can exclude taskbars.
Is this a color calibrator?
No. Color depth is informational only. It does not calibrate or profile a display.
Is this screen resolution viewer free?
Yes. Unlimited use with no signup.
