Image DPI & Print Size Calculator
Convert image pixels into physical print dimensions and vice versa. Calculate DPI from known pixel and print sizes. Compare quality at standard DPI benchmarks (150, 200, 300, 600).

Ask things like: "What subnet mask should I use for 100 hosts?", "How do I calculate the broadcast address?", "What's the difference between /24 and /25?", or "Is 10.0.0.1 a public or private IP?".

Understanding DPI, PPI & Print Quality
DPI (Dots Per Inch) refers to the number of ink dots a printer places within a linear inch on paper. Higher DPI generally means finer detail in printed output.
PPI (Pixels Per Inch) describes the density of pixels in a digital image. When preparing images for print, PPI and DPI are often used interchangeably, though they technically measure different things.
Key Formula: Print Size (inches) = Pixel Dimension ÷ DPI
Frequently Asked Questions
DPI (Dots Per Inch) refers to the physical dots of ink a printer can place per inch. PPI (Pixels Per Inch) refers to the pixel density in a digital image. When preparing images for print, they're often used interchangeably since your image's PPI becomes the printer's target DPI.
