What is DPI?
DPI = dots per inch. For print: 300 DPI is standard. For web: 72–96 DPI is sufficient—screens display in pixels.
DPI for Print
Print shops typically require 300 DPI for high-quality output. Images at 72 DPI will look blurry when printed.
DPI for Web
For web, DPI doesn't matter—pixel dimensions do. A 1920×1080 image works well for a banner.
