What is Inches to Pixels Converter?

The standard inches to pixels conversion is fixed by the CSS specification: 1 inch = 96px. This is because CSS uses a reference density of 96 pixels per inch (96 ppi), regardless of your screen's physical resolution.

The formula is straightforward: **px = inches × 96**. So 2 inches is 192px, 0.5 inches is 48px, and 8.5 inches (US Letter width) is 816px.

This conversion is most useful when translating print design specs or physical layout measurements into CSS values. Use the conversion table below for common inch-to-pixel reference values.

How to Use Inches to Pixels Converter

Frequently Asked Questions

Is 1 inch always 96px?

In CSS, yes — 1in = 96px is a fixed definition. On high-DPI screens, the browser handles the physical pixel mapping; you always work with CSS pixels at this ratio.

What is the standard paper width in pixels?

US Letter (8.5in) = 816px. A4 width (8.27in) ≈ 794px. These are useful for print CSS layouts.

How does this relate to points and centimetres?

1in = 96px = 72pt = 2.54cm in CSS. All CSS absolute units are interconvertible at 96dpi.
