In the graphics’ world, resolution can make or break your day. It’s very important to have images that are high resolution because it determines the quality of your picture. But what is resolution?
Resolution is how much detail one image holds. It’s measured by how many pixels there are per inch (ppi). The higher the ppi the better quality of the image.
For printing, it’s best to have images no less than 300ppi. Otherwise, there is a chance that your images will print pixelated and grainy.
