Questions
- What is the difference between DPI and PPI?
- PPI (pixels per inch) describes an image file: how many pixels cover each inch when it is printed. DPI (dots per inch) is how finely a printer lays down ink. People use “DPI” for both; for checking an image, what matters is pixels per inch at the final print size.
- Does changing an image from 72 dpi to 300 dpi make it sharper?
- No. The dpi number in a file is only a label. Sharpness depends on the pixel count: a 1050 × 600 pixel image is 300 ppi at 3.5 × 2 inches whatever its file says. Upscaling adds pixels but not detail.
- How many pixels do I need for a business card?
- With 0.125 inch bleed a business card is 3.75 × 2.25 inches, so at 300 ppi you need 1125 × 675 pixels.
