Just so, what is the size of a 300 dpi image?
Since the resolution is 300 dpi, it means thateach inch is 300 pixels across. As the image is 8inches wide that means there are 2,400 pixels in width (8 x300). Likewise, as the image is 12 inches long, theimage is 3,600 pixels in length (12 x300).
Furthermore, is 300 dpi considered high resolution? All files must have a minimum resolution of300 dpi (dots per inch). Images with a resolutionless than 300 dpi will reproduce poorly on press (the imagewill look fuzzy and/or pixilated). Below are examples of a lowresolution (72 dpi) file and a high resolution(300 dpi) file.
