Inches to Pixels Converter

What is Inches to Pixels Converter?

Inches to Pixels converter translates physical inch measurements into pixel values based on the target DPI resolution, and converts pixels back to inches. The web standard of 96 DPI maps 1 inch to exactly 96 CSS pixels, while print workflows use 150, 300, or 600 DPI. The tool supports fractional inches and provides a visual ruler calibration feature that lets you measure a physical inch on your screen to determine your display's actual PPI for precise screen-based measurements.

Print designers converting layouts to digital, photographers sizing prints, and web developers working with physical measurement specifications. The tool runs entirely in your browser — your data never leaves your device.

How to Use Inches to Pixels Converter

1. Enter the measurement in inches (supports decimals and fractions like 8.5 or 3 1/4)
2. Set the DPI — 96 for web, 150 for draft print, 300 for professional print
3. View the pixel result along with centimeter and millimeter equivalents
4. Use the ruler calibration tool to determine your screen's actual PPI for accurate on-screen measurement

Common Use Cases

• Converting print design measurements (8.5 x 11 inches) to pixel dimensions for digital mockups
• Determining how many pixels wide a 3-inch column will be at various DPI settings
• Calculating the physical print size of an image based on its pixel dimensions
• Setting up design files with correct pixel dimensions for a target physical output size

Pro Tips

• For web: 1 inch = 96 CSS pixels, always — this is a fixed definition in CSS, not a measurement of physical pixels; the actual physical size depends on the device's pixel density
• A standard US letter page (8.5 x 11 inches) at 300 DPI requires a 2550 x 3300 pixel image — this is the minimum resolution for professional print quality
• Your browser's CSS inch (96px) likely does NOT match a physical inch on your screen — hold a ruler up to verify; most monitors show CSS inches as slightly larger or smaller than true inches
