is the "Goldilocks" resolution for the average user. On a laptop screen (14-15 inches) or a mobile device, the difference between 720p and 1080p is often negligible to the naked eye. A typical 720p dual audio movie (x264 codec) weighs between 800 MB to 1.5 GB. This makes it easy to download over mobile data, store on a pen drive, or stream without buffering. For the functional viewer who prioritizes story and audio clarity over extreme detail, 720p is superior.
