Calculate effective DPI
Effective DPI tells you how many image pixels fit into each printed inch. Enter pixel width and planned print width to calculate DPI and get a quick quality hint. It is useful for checking photos, posters, design exports and artwork before sending files to print.
Resolution reality check
DPI is only one part of print quality, but it is a fast way to spot images that may be too small for the intended print size.
Frequently asked questions
What does DPI mean?
DPI means dots per inch, and in this calculator it represents effective pixels per printed inch.
Is lower DPI always bad?
Not always. Large prints viewed from a distance can use lower DPI.
Does this calculate both width and height?
This compact version uses width. Check height separately if the image is tightly constrained.
