Printing requires higher resolution than screen display. At 300 DPI (dots per inch), a 4×6 inch print needs 1200×1800 pixels. This tool helps you resize to the exact pixel dimensions for any print size.
Images that look great on screen may print blurry if they do not have enough pixels. 300 DPI is the standard for sharp photo prints.
