PX to PPI Converter 

PPI (Pixels Per Inch) measures the pixel density of a digital image or display. Unlike DPI (Dots Per Inch), which is used for print, PPI describes the sharpness and clarity of images on screens.

For example:

  • 72 PPI – Standard web resolution.
  • 220 PPI – Retina-quality screens on modern devices.
  • 300 PPI+ – Ultra-high-definition displays.

Why Use a PX to PPI Converter?

Converting between pixels and PPI helps you understand the image quality and physical print size. This tool is useful for:

  • Checking if an image is high enough resolution for printing.
  • Comparing screen sharpness between devices.
  • Ensuring consistency between digital and print design workflows.
  • Saving time by automating pixel density calculations.

How to Use the Converter

  1. Enter your image pixel dimensions (width × height).
  2. Enter the physical size of the display or print (in inches).
  3. The calculator provides the PPI value instantly.

Formula:

PPI = Pixels ÷ Inches

Example:

  • Image width: 3000px
  • Display/print width: 10 inches
  • PPI = 300

Best Practices for PPI

  • Web graphics: 72 PPI is fine — screens map pixels directly.
  • High-quality prints: At least 300 PPI for professional output.
  • Retina/HiDPI displays: Aim for 200–400 PPI for crisp detail.
  • Large displays/posters: Can work with lower PPI (100–150) since viewed from farther away.

FAQs

What’s the difference between PPI and DPI?

  • PPI = pixel density on digital screens.
  • DPI = dot density in print.

How many pixels per inch is “Retina”?
Apple’s “Retina” usually refers to 220 PPI or higher, depending on screen size.

Does higher PPI mean better quality?
Yes — higher PPI means sharper images, but only up to the limit of human perception.

What PPI should I use for printing photos?
At least 300 PPI for professional-quality prints.Can I increase PPI without adding pixels?
No. PPI depends on both pixel count and physical size — resizing affects the value.
