DPI (Dots Per Inch) measures the resolution density of an image when printed. A higher DPI means more detail and sharpness in print. Standard print quality is 300 DPI, while web images typically use 72-96 DPI since screens measure resolution in pixels, not dots.
DPI is a print-centric measurement that describes how many ink dots fit in one linear inch. At 300 DPI — the standard for professional printing — a 3000x2000 pixel image prints at 10x6.67 inches. At 72 DPI, the same image would print at 41.7x27.8 inches but with much less detail visible up close.
For screens, DPI (often called PPI — Pixels Per Inch) describes pixel density. A standard monitor runs at about 96 PPI, while Retina/HiDPI displays reach 200-400+ PPI. When preparing images for the web, the pixel dimensions matter more than the DPI metadata. A 1200px wide image looks the same in a browser whether its metadata says 72 DPI or 300 DPI.
Where DPI matters critically is print production. Sending a 72 DPI image to a printer results in blurry, pixelated output. Professional print workflows require 300 DPI at the final print size. For large-format printing (banners, billboards), 150 DPI is often sufficient because viewers stand further away.
