Question

How can I get windowWidth, windowHeight, pageWidth, pageHeight, screenWidth, screenHeight,

Answer 1

To check height and width of your current loaded page of any website using "console" or after clicking "Inspect".

step 1: Click the right button of mouse and click on 'Inspect' and then click 'console'

step 2: Make sure that your browser screen should be not in 'maximize' mode. If the browser screen is in 'maximize' mode, you need to first click the maximize button (present either at right or left top corner) and un-maximize it.

step 3: Now, write the following after the greater than sign ('>') i.e.

       > window.innerWidth
            output : your present window width in px (say 749)

       > window.innerHeight
            output : your present window height in px (say 359)
