If you are wondering what DPI is and you’ve heard the term before or maybe you have seen it, we can define this term for you in the world of printing. We will first discuss it with beginning explaining a high-quality image, which means the highest resolution and image dimensions. When it comes to source images, bigger is better, because you can go down in size, but not up, without losing quality. Here are the definitions below to explain further:
DPI: Means dot’s per inch. The number of dots in a printed inch. The more dot’s the higher the quality of the print, which allows for more sharpness and detail.
PPI: means pixels per inch. Most commonly used to describe the pixel density of a screen (i.e. a computer monitor, smartphone, etc.) but can also refer to the pixel density of an digital image.
Resolution: means the resolution that is the measure of pixels in the display, usually expressed in measurements of width x height.
Higher resolution means more detail. Higher DPI means higher resolution. Resolution is not the size of the image, but it’s often confused with it because those type of images are often bigger.
Print: 300dpi is standard, sometimes 150 is acceptable but never lower, you may go higher for some situations.
Web/Digital: DPI doesn’t equate to digital it’s a print measure. When talking digital, we’re concerned with the actual resolution. How that image prints is another matter.
A monitor set to 1024 x 768 and will show a 1024 pixel wide by 800-pixel tall image as a full-screen image. On a monitor that is 1920x 1080, the image will only take up part of the screen. In conclusion, the image will look much smaller on that screen even though the image is the same size because the screen has higher resolution.
