System FAQ

How do I convert pixels to inches?

Divide the number of pixels by the DPI (dots per inch): Inches = Pixels ÷ DPI. For example, at 96 DPI (standard screen), 960 pixels = 960 ÷ 96 = 10 inches. At 300 DPI (print), 960 pixels = 3.2 inches.

What DPI should I use for printing?

Standard print quality: 300 DPI. High-quality photography: 300-600 DPI. Standard web display: 72-96 DPI. For printing a 4×6 inch photo at 300 DPI, you need 1200×1800 pixels minimum.

What is the difference between DPI and PPI?

PPI (Pixels Per Inch) refers to digital screen density — how many pixels fit in one inch of screen. DPI (Dots Per Inch) refers to printer resolution. In practice, CSS and web design treat 1 inch = 96 pixels regardless of actual screen PPI.

Why does 96 PPI equal 1 inch in CSS?

CSS uses a reference pixel where 1 inch = 96px as a standard, regardless of your physical monitor's actual PPI. This ensures consistent layout across different screen densities. High-DPI (Retina) screens scale this up visually.

How many pixels is an A4 page at 300 DPI?

An A4 page (210mm × 297mm or 8.27" × 11.69") at 300 DPI = 2480 × 3508 pixels. At 72 DPI (screen), it's 595 × 842 pixels.
