Pixels to Inches Converter
Instantly convert pixelsto inches with our free converter. See conversion tables, formulas, and step-by-step explanations.
Formula
Inches = Pixels / DPI
Where Inches = physical size in inches, Pixels = number of pixels (digital dimension), DPI = dots per inch (resolution). To convert inches to pixels, multiply: Pixels = Inches x DPI. This formula applies to both screen (PPI) and print (DPI) contexts.
Worked Examples
Example 1: Web Image Print Size
Problem: A website banner is 1200 pixels wide at 96 DPI. How wide will it be when printed at 300 DPI?
Solution: On screen at 96 DPI:\nWidth = 1200 / 96 = 12.5 inches\n\nWhen printed at 300 DPI:\nWidth = 1200 / 300 = 4.0 inches\n\nThe printed banner is only 4 inches wide because the printer packs more pixels per inch.
Result: Screen: 12.5 inches | Print (300 DPI): 4.0 inches
Example 2: Required Pixels for A4 Print
Problem: How many pixels wide must an image be to print on A4 paper (8.27 inches wide) at 300 DPI?
Solution: Pixels = Inches x DPI\nPixels = 8.27 x 300\nPixels = 2,481 pixels wide\n\nFor the full A4 (8.27 x 11.69 inches):\nWidth: 2,481 pixels\nHeight: 3,507 pixels\nTotal: approximately 8.7 megapixels
Result: A4 at 300 DPI: 2,481 x 3,507 pixels (8.7 megapixels)
Frequently Asked Questions
How do you convert pixels to inches?
To convert pixels to inches, divide the number of pixels by the DPI (dots per inch) or PPI (pixels per inch) of your display or print output. The formula is simply: Inches = Pixels / DPI. For example, 1920 pixels at 96 DPI equals 20 inches (1920 / 96 = 20). The DPI value is crucial because it determines how many pixels fit into each physical inch. A standard computer monitor typically uses 96 DPI, while Retina displays use 144 or higher, and print-quality output requires 300 DPI or more. The same 1920 pixels would measure only 6.4 inches at 300 DPI.
