Resolution vs DPI

Resolution is how many pixels an image has; DPI is how densely they print. Why screens ignore DPI and how many pixels you need for print sizes.

Upscale for printGet the pixels the print math asks for.

The plain-English answer

Resolution is the pixel count of an image (say, 3000×2400); DPI — dots per inch — is how densely those pixels are placed when printed. Screens only care about resolution; DPI only matters on paper. A "300 DPI" requirement really means: enough pixels that, at your print size, each inch gets 300 of them.

The confusion dissolves with one formula: pixels = inches × DPI. An 8×10 print at 300 DPI needs 2400×3000 pixels — that's it. The DPI number stored in a file changes nothing on screen; two identical JPGs at "72 DPI" and "300 DPI" look pixel-for-pixel the same on any display.

So for web work, think purely in pixels; for print, work backward from physical size — and if you're short of pixels, AI upscaling adds them convincingly.

Frequently asked questions

Is higher DPI always better?+
Beyond what the eye resolves at viewing distance, no. 300 DPI is the standard for handheld print; posters viewed from meters away are fine at 150.
How do I make an image 300 DPI?+
Ensure it has enough pixels for the print size (inches × 300). Changing the DPI tag without adding pixels changes nothing real — upscale if the pixels aren't there.
Why does my print look pixelated when the screen version looks fine?+
Screens display ~100-200 pixels per inch; print needs ~300. An image that fills a monitor can still be far too small for a sharp 8×10.
