Size

Screen resolution and screen size are two different things. If you combine them, it's called "pixel density":

  • Screen size (cm × cm or the diagonal in inch): How big is the device? That is relevant to check if it fits in your hands in case of a smartphone or in your living room in case of a TV.
  • Resolution (pixel per row × pixel per colum): How many details can you see in one still image?
  • Pixel density (pixel per inch): How close do you have to go to see individual pixels?
