Understanding Image Resolution and DPI: What You Need to Know

Resolution and DPI are often confused, but they are different things. Resolution refers to the number of pixels in an image, while DPI (dots per inch) refers to the density of dots in a printed image.

Resolution for Web

For the web, the most important thing is the total pixel count. A common resolution for web images is 72 PPI (pixels per inch).

DPI for Print

For printing, you usually need a much higher DPI, typically 300 DPI, to ensure your images look sharp on paper.

Conclusion

Knowing the difference between resolution and DPI will help you create better images for any medium.
