Pixel Density

Pixel Density

The measurement of number of pixels present in a confined area is called as Pixel Density. Usually measured within an inch and hence termed as PPI (Pixels Per Inch). When the PPI increases, the screen has a better sharpness of image.

When a display has a PPI of more than 300, they are hard for human eyes to distinguish individual pixels. Hence it will look more crisp and clear. Resolution is completely different from Pixel density.

With more number of pixels in a small area, the display looks more crispier. Images can be with more details and sharper. Pixel density alone can stand to represent the sharpness of an image. With whatever size of display screen, PPI always represents the number of pixels in same area. So it is easier to know how sharp the screen could produce the image.
