    Pixel Density Calculator

    Calculate PPI/DPI for screens and prints

    Quick examples:
    Pixel Density
    92 PPI
    Low Density
    Aspect Ratio
    1.78:1
    Diagonal (px)
    2203
    Physical Width
    20.92"
    Physical Height
    11.77"

    💡 What This Means

    • There are 92 pixels per inch on this screen
    • Total resolution: 1920 × 1080 (2.07MP)
    • Consider a higher resolution screen for better clarity

    Understanding Pixel Density

    PPI vs DPI

    • PPI (Pixels Per Inch): Used for screens and digital displays
    • DPI (Dots Per Inch): Used for printers and print resolution
    • Both measure the density of pixels or dots in a given area
    • Higher PPI/DPI = sharper, more detailed images

    Common Screen Densities

    • ~90 PPI: Standard desktop monitors (24" 1080p)
    • ~110 PPI: 27" 1440p monitors
    • ~160 PPI: 27" 4K monitors
    • ~220 PPI: MacBook Pro Retina displays
    • ~460 PPI: iPhone/high-end smartphones

    Print Guidelines

    • 300 DPI: Professional printing standard
    • 150-200 DPI: Acceptable for most prints
    • 72 DPI: Web/screen standard (not for printing)
    • Consider viewing distance - larger prints can use lower DPI
