Understanding DPI vs PPI
DPI (dots per inch) and PPI (pixels per inch) are often used interchangeably but technically differ. DPI refers to printer dots, while PPI refers to screen pixels.
For practical purposes, they measure the same thing: resolution density. Common values: 72-96 PPI for screens (though modern displays are much higher), 300 DPI for quality printing, 150-200 DPI for large-format printing.
Higher values mean more detail but larger file sizes. The right value depends on output medium and viewing distance.
Quick Tips
- 1 mile = 1.609 km (miles are bigger)
- 1 kg = 2.205 lbs (roughly double + 10%)
- Temperature: (°F - 32) × 5/9 = °C
Frequently Asked Questions
DPI is for printers (dots), PPI is for screens (pixels). Often used interchangeably.
300 DPI for standard prints, 150-200 DPI for large posters.
Varies widely. Modern phones: 300-500 PPI, monitors: 90-220 PPI, 4K displays: higher.
Not after the fact. You need more pixels captured/created originally.
