How to use the What's My Screen Resolution

  1. Open the page — your details appear immediately.
  2. Resize the window to watch the viewport change.
  3. Copy everything for a support ticket if needed.

What does this tool do?

Web pages see “CSS pixels”, which are usually fewer than the screen's physical pixels. On a phone with a device pixel ratio of 3, a 390 px wide viewport is 1,170 physical pixels across.

Why use it?

  • Report display details to support teams.
  • Test responsive designs.
  • Check high-DPI (retina) displays.

Common viewport widths

Phones: about 360–430 px. Tablets: 768–1,024 px. Laptops: 1,280–1,536 px. Desktop monitors: 1,920 px and up.
