Help! I have a 3 x 5 ft banner I'm making but I'm not sure about the photograph they want included. How do I know if the photograph will work? Need advice ASAP! From resolution to size of image...
The size of your photograph will be be different depending on the DPI you are printing at. DPI = dots per inch. So if you are printing at 300 DPI you will need:
300 dpi * 5 feet * 12 inches = 18,000px 300 dpi * 3 feet * 12 inches = 10,800px
However, this is WAY more than 14mp! I recommend printing at 72 DPI for large prints, it will still look fine and your image will actually fit.
72 dpi * 5 feet * 12 inches = 4,320px 72 dpi * 3 feet * 12 inches = 2,592px
This translates to about 14mp.
