Frequently Asked Questions
What is the difference between PPI and DPI?
PPI (Pixels Per Inch) measures pixel density on screens, while DPI (Dots Per Inch) measures dot density in print. PPI is for displays; DPI is for printers.
What are the benefits of a high PPI?
Higher PPI means denser pixels and a sharper image. Displays above 300 PPI are generally considered 'retina' quality, where individual pixels are indistinguishable to the naked eye.
What DPI should I use for printing?
Standard documents need 150-300 DPI, high-quality photo prints require 300+ DPI, and large banners can use 72-150 DPI since they are viewed from a distance.
