DPI vs PPI
DPI (Dots Per Inch) refers to print resolution; PPI (Pixels Per Inch) refers to digital image resolution. For web and e-commerce, PPI is the relevant metric.
What is DPI vs PPI?
A common confusion in e-commerce is equating DPI with image quality. For websites and marketplaces, what matters is pixel dimensions (e.g., 2000×2000 pixels), not DPI. An image can be 72 DPI but 4000×4000px — it will look excellent online. DPI only matters when printing. Amazon and Shopify require minimum pixel dimensions, not DPI specifications.
E-Commerce Relevance
Understanding pixel dimensions vs. DPI prevents the common mistake of thinking '300 DPI' means high quality for web — pixel count is what matters.
