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 inches): 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 (pixels per row × pixels per column): How many details can you see in one still image?
- Pixel density (pixels per inch): How close do you have to go to see individual pixels?
