    Quick Facts

    • •300 DPI = standard print quality
    • •72 DPI = web/screen standard
    • •A 4×6" photo at 300 DPI = 1,200 × 1,800 px

    What Is DPI?

    DPI (Dots Per Inch) measures print resolution — the number of ink dots per inch. Higher DPI means sharper prints. Screen resolution uses PPI (Pixels Per Inch) which is conceptually similar. Standard print quality is 300 DPI, while web images are typically 72–96 DPI.

    How to Calculate Pixels from DPI

    Pixels = DPI × Physical Size (inches). For example, an 8.5×11" document at 300 DPI = 2,550 × 3,300 pixels. This calculation is essential for photographers, graphic designers, and anyone preparing images for print.
