Screen: width property
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The Screen.width read-only property returns the width of
the screen in CSS pixels.
Value
A number.
Examples
js
// Crude way to check that the screen is at least 1024x768
if (window.screen.width >= 1024 && window.screen.height >= 768) {
// Resolution is 1024x768 or above
}
Notes
Note that not all of the width given by this property may be available to the window
itself. When other widgets occupy space that cannot be used by the window
object, there is a difference in window.screen.width and
window.screen.availWidth. See also screen.height.
