Calculate Display Density
Our PPI (Pixels Per Inch) Calculator helps you determine the pixel density of displays and images. This is crucial for:
- Screen resolution analysis
- Image quality assessment
- Display manufacturing
- Digital design
- Print preparation
How to Use Our PPI Calculator
- Enter the display/image width in pixels
- Enter the display/image height in pixels
- Input the diagonal screen size in inches
- Get the calculated PPI value
- View additional display metrics
The calculator provides:
- Pixels Per Inch (PPI)
- Total pixel count
- Aspect ratio
- Display area
- Pixel density category (e.g., Retina, HD, 4K)
The formula used is: PPI = √(width² + height²) ÷ diagonal size
Note: Higher PPI values generally indicate sharper images and clearer text. For reference, “Retina” displays typically have 220+ PPI, while 4K monitors often range from 140-200 PPI depending on size.
