Understanding Image Resolution Units
DPI (Dots Per Inch)
DPI measures how many dots a printer can place in one inch. Higher DPI means better print quality. Standard values are 72 DPI for web and 300 DPI for print.
PPI (Pixels Per Inch)
PPI measures pixel density in digital images. It determines how sharp an image appears on screen. Most monitors display at 72-96 PPI, while high-resolution displays can reach 300+ PPI.
Pixels Per Centimeter
This metric system unit measures pixel density per centimeter. It's commonly used in international printing and design. To convert from DPI, divide by 2.54.

Frequently Asked Questions
What is the difference between DPI and PPI?
DPI (dots per inch) refers to printer resolution, while PPI (pixels per inch) refers to digital image resolution. They measure different things but often have the same numerical value.
What resolution should I use for printing?
For high-quality photo printing, use 300 DPI. For professional documents with text, 600 DPI is recommended. Draft prints can use 150 DPI.
How do I convert DPI to pixels per centimeter?
Divide the DPI value by 2.54. For example, 300 DPI ÷ 2.54 = 118.11 pixels per centimeter.
What resolution is best for web images?
Web images typically use 72-96 PPI. Higher resolutions increase file size without improving display quality on most screens.
Can I increase image resolution after taking a photo?
You cannot truly increase resolution beyond the original capture. Upscaling adds pixels but doesn't add real detail to the image.
Why does my image look blurry when printed?
This usually happens when the image resolution is too low for the print size. Ensure your image has at least 300 DPI at the intended print dimensions.
