How many pixels in an inch?

It depends on DPI. At 96 DPI (the screen default), 1 inch is 96 pixels. At 300 DPI (the print standard), 1 inch is 300 pixels. At 600 DPI (high-quality offset), 1 inch is 600 pixels. Formula: pixels = inches × DPI.

What is the pixel size for A4 at 300 DPI?

How do I convert inches to pixels for printing?

Multiply the inch dimension by your target DPI. For an 8 × 10 in photo at 300 DPI, that is 8 × 300 = 2400 px wide and 10 × 300 = 3000 px tall — export at 2400 × 3000 px or larger. For a 4 × 6 in postcard at 300 DPI, you need 1200 × 1800 px.
