What is PPI?

PPI (Pixels Per Inch) is a measure of pixel density that indicates how many pixels are displayed per inch of screen space. Higher PPI values result in sharper, more detailed images.

Formula: PPI = √(Width² + Height²) ÷ Diagonal Size

Common PPI Values:

• 72 PPI: Standard web resolution
• 96 PPI: Windows default
• 300 PPI: Print quality
• 400+ PPI: High-end displays

Example Calculations:

• 1920×1080, 24": ~92 PPI
• 2560×1440, 27": ~109 PPI
• 3840×2160, 32": ~138 PPI
