Inches to Pixels Calculator
Choose Print/Image for PPI-based raster conversion or Web/CSS for the W3C 96 CSS px-per-inch reference relationship.
Choose what the pixels are for
Web/CSS pixels use the CSS reference relationship of 96 px per inch. Raster print pixels depend on the PPI you choose for the final physical size.

CSS pixels and print pixels are not the same question
For CSS absolute lengths, the W3C reference relationship is 1 in = 96 px and 1 cm = 96 ÷ 2.54 px. For a raster print, pixel count depends on the chosen PPI. The calculator above lets you choose the context instead of silently assuming one.
| Inches | CSS reference | 150 PPI print | 300 PPI print |
|---|---|---|---|
| 1 | 96 px | 150 px | 300 px |
| 2 | 192 px | 300 px | 600 px |
| 4 | 384 px | 600 px | 1,200 px |
| 8 | 768 px | 1,200 px | 2,400 px |
| 10 | 960 px | 1,500 px | 3,000 px |
What the result is useful for
Use this when a physical width in inches must become either a raster-print pixel dimension at a chosen PPI or a CSS reference length at 96 px/in; separating those contexts prevents a common conversion mistake.
How the calculation works
Print pixels = inches × PPI. In Web/CSS mode, the reference conversion uses 96 CSS px per inch.
What this calculator cannot know
The math can describe pixels, PPI and geometry, but it cannot judge subject detail, sharpening, resampling quality, printer process, media or viewing distance. Use the output provider’s requirement when one exists.
