This is a old video. According to video Width x Height = Pixel Dimensions. But this does not come to me. What do you think?

Pixels, Image Size and Resolution

Time around 2.35

    The top line is the size in memory, in megabytes (not megapixels). Where it says pixel dimensions in your old screenshot, it now says image size to clarify the distinction.

     

    Each pixel is 8 or 16 bits (one or two bytes) x three or four channels. If you multiply that with the pixel dimensions, you get the number at the top.

     

    Also keep in mind that one kilobyte is not 1000, but 1024 bytes.

      @MahaB82A do you want an easy way to calculate/report the megapixel value?
