About the what is my screen resolution?
Find out your screen resolution and everything else your browser reports about your display: available screen size, the current viewport, device pixel ratio, physical pixels, colour depth and orientation. It also shows your browser, operating system, time zone, language and accessibility preferences, which is handy for bug reports and responsive design testing. All values are read on your device.
How to use it
- Open the page — your screen resolution appears at the top.
- Resize the window or rotate your phone to watch the viewport update.
- Press Copy all to paste every value into a bug report or support ticket.
Questions
- Why is my screen resolution smaller than my monitor's specification?
- Browsers report size in CSS pixels. On high-density displays the device pixel ratio is above 1, so a 2560 × 1600 panel at a ratio of 2 reports 1280 × 800. The physical pixels row multiplies them back out.
- What is the difference between screen size and viewport?
- Screen size is the whole display. The viewport is the area inside the browser window that a web page can draw in, which excludes toolbars and changes when you resize the window.
- What is device pixel ratio?
- It is the number of physical pixels per CSS pixel. It is 1 on standard displays, 2 or 3 on most phones and Retina screens, and it also changes when you zoom the page.
- Why might the browser or OS shown be wrong?
- They are detected from the user agent, which browsers increasingly reduce or freeze for privacy. Treat those two rows as a best guess.
