What Is Image Resolution in Photoshop? (72 DPI vs 300 DPI Explained)
What’s the difference between 72 DPI and 300 DPI in Photoshop — and why does it matter?
In this quick Photoshop tutorial, I explain the basics of image resolution and how it affects print quality vs on-screen display. I open an image, show how it looks at different resolutions, and explain why PPI (pixels per inch) is the key to getting sharp, professional print results.
What you’ll learn:
What 72 DPI and 300 DPI actually mean
How image resolution affects print size — not how it looks on screen
Why 300 PPI is the industry standard for high-quality printing
The difference between PPI and DPI (and why the terms get mixed up)
📌 Photoshop technically uses PPI (Pixels Per Inch) — that’s what you’ll see in the Image Size panel. But DPI (Dots Per Inch) is often used interchangeably when talking about printing. Same idea, different medium.
🖨️ If you're designing for print — flyers, packaging, business cards, apparel — you need to know this.
