FAQ

What is DPI?

DPI (Dots Per Inch) measures print resolution. Higher DPI means sharper printed images. 72 DPI is screen standard, 300 DPI is print standard.

How to calculate DPI?

DPI = √(width² + height²) ÷ diagonal. For a 1920×1080 24-inch display: √(1920² + 1080²) ÷ 24 ≈ 91.8 DPI.

What print size can I get?

Print size = pixels ÷ DPI. At 300 DPI, a 1920×1080 image prints at 6.4 × 3.6 inches (16.3 × 9.1 cm).
