Resolution: Detail Level of an Image
Resolution describes the amount of detail in an image, usually expressed as pixel dimensions and the effective PPI at a given size.
Resolution is not a single number. A file can be 4000 x 3000 px, and its effective resolution changes depending on how large you place or print it. Higher resolution helps with print clarity, but it increases file size and can slow workflows.
Example
A 2400 x 3000 px image printed at 8 x 10 inches results in 300 PPI. Printed at 16 x 20 inches it drops to 150 PPI and looks softer up close.
Frequently Asked Questions
Image size is the physical output size. Resolution connects pixel dimensions to that size, determining how sharp it appears.
No. Modern web uses pixel dimensions, not a fixed DPI. The “72 DPI” idea is legacy metadata from older systems.
Use vector whenever possible. If you must use raster, use very high pixel dimensions and avoid scaling up.
Common causes are low pixel dimensions, scaling up in layout, aggressive compression, or exporting at the wrong size.
Consider viewing distance. Billboards can be lower PPI up close because they are viewed from far away. Ask the printer for a target PPI.
