How to Convert Inches to PX

Multiply by the resolution:
px = inches × DPI

At 96 DPI, 4 inches = 4 × 96 = 384 px. At 300 DPI, 4 × 6 inches = 1200 × 1800 px.

Note: a "27-inch monitor" measures the screen diagonal. That has nothing to do with CSS inches, which are always 96 CSS pixels.

Which DPI Should You Use?

96 DPI — websites and CSS. Browsers treat 1 inch as 96 CSS pixels on every device, so this gives the size in your stylesheet.
150 DPI — drafts and office printing. Fine for documents that are read rather than inspected closely.
300 DPI — print quality. The standard for photos, ID pictures, posters and anything printed professionally.

The inch on paper never changes — only how many pixels you need to fill it. More DPI means more pixels for the same physical size, and a sharper print.
