Editor to share with you what 300dpi means, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to understand it!

300dpi means that there are 300 pixel units in an inch of area. DPI refers to pixels per inch, that is, scanning accuracy. Currently, the default is to calculate the number of pixels in an inch area; the lower the DPI, the lower the definition of the scan.

300dpi means that there are 300 pixel units in an inch of area.

DPI (Dots Per Inch, dots per inch) is a unit of measurement used in dot matrix digital images, which refers to the number of points that can be sampled, displayed, or output per inch in length. At present, the default is the unit that calculates the number of pixels in an inch of area.

DPI is a unit of measurement of the resolution of devices such as printers, mice, and so on. It is one of the main parameters to measure the printing accuracy of the printer. generally speaking, the higher the DPI value, the higher the printing accuracy of the printer.

DPI refers to pixels per inch, that is, scanning accuracy. The lower the DPI, the lower the definition of the scan. Due to the influence of the network transmission speed, the images used on the web are all 72dpi, but this parameter cannot be used to develop photos. It must be 300dpi or higher 350dpi. For example, to develop a 4'6 inch photo, the scanning accuracy must be 300dpi, then the file size should be (4 '300) * (6' 300) = 1200 pixels * 1800 pixels.

Extended data:

DPI was originally a unit of measurement in printing, meaning the number of dots per inch that can be printed (Dot Per Inch). However, with the rapid development of digital input and output equipment, most people also express the resolution of digital images with DPI, but more rigorous people may notice that the dot (Dot) calculated when printing and the display pixels (Pixel) of computer monitors are not the same, so more professionals will use PPI (Pixel Per Inch) to express the resolution of digital images to distinguish between the two.

We usually refer to the printer resolution DPI, which refers to the maximum number of ink dots per inch that can be printed in the printer's highest resolution mode.
