2. Image size calculation
Description of units
PPI = Pixels per inch
DPI = Dots per inch
PPC = Pixels per centimeter
1 inch = 2.54 cm
1 cm = 0.39 inches
300 DPI = 118.11 ppc (rounded up to 120 ppc)
Pixels: 120 ppc = Size (100%) in cm at 120 ppc (300 DPI) Pixels: 300 ppi = Size (100%) in inches at 300 ppi (300 DPI)
Example 1
The image has a width of 4800 pixels. What is the maximum size at which this image can be printed?
1. 4800 : 120 ppc = 40 cm at 300 DPI
2. 4800 : 300 ppi = 16 inches at 300 DPI
Example 2
You want to print a full-page image on A4 paper (21 x 29.7 cm / 8.27 x 11.42 inches). What should the image size be?
1. 21 cm x 120 ppc = 2520 pixels
2. 29.7 cm x 120 ppc = 3564 pixels
1. 8.27 inches x 300 ppi = 2481 pixels
2. 11.42 inches x 300 ppi = 3426 pixels
