Inches to Pixels Calculator: Convert in to px Easily
Use this tool to convert inches to pixels quickly and accurately. Ideal for web designers, graphic artists, printers, and developers who need precise screen or print resolutions.
Understanding the Conversion from Inches to Pixels
Inches and pixels are two entirely different measurement units but are often converted in digital design, printing, and web development. Inches measure physical length, while pixels represent the smallest visible unit of a digital display. To accurately convert inches to pixels, you need to know the resolution or DPI (dots per inch) of the device or medium you're working with.
What Is an Inch?
An inch is a unit of length in the imperial and U.S. customary measurement systems, equal to 1/12 of a foot or exactly 25.4 millimeters. In the physical world, inches are used to describe the size of screens, paper, images, and many manufactured products.
What Is a Pixel?
A pixel (short for “picture element”) is the smallest controllable element of a digital image or display. Pixels have no inherent size in the real world; their physical size depends entirely on the device's resolution. The higher the DPI, the smaller each pixel becomes physically.
What Is DPI?
DPI, or Dots Per Inch, indicates how many individual dots (or pixels) fit into one inch of physical space. It defines how densely the pixels are packed, influencing the sharpness and clarity of digital and printed images.
Conversion Formula
Pixels = Inches × DPI
Example: 5 inches × 300 DPI = 1500 pixelsCommon DPI Standards
- 72 DPI: Legacy web standard
- 96 DPI: Default screen resolution (most modern browsers)
- 150 DPI: Medium quality prints
- 300 DPI: High-quality print resolution
- 600 DPI: Professional photo printing
- 1200+ DPI: Specialized high-end printing (e.g., professional publishing)

FAQ: Inches to Pixels
How many pixels are in one inch?
It depends on the DPI. For example, at 300 DPI, 1 inch equals 300 pixels.
What DPI should I use for printing?
300 DPI is generally recommended for high-quality prints, while 150 DPI may suffice for basic prints.
Is DPI the same for all devices?
No. Monitors, printers, and smartphones often have different DPIs. Always check the specific device specs.
Can I convert pixels to inches?
Yes, but you need to know the DPI. The formula is: Inches = Pixels ÷ DPI.
Why does my image look different on screen and on paper?
Because screens and printers may use different DPIs, images can appear larger or smaller depending on the output medium.
International Relevance
While inches remain common in the United States for measuring physical sizes, pixels have become a universal digital unit across the globe. Regardless of region, accurate conversion is crucial for any professional involved in design, publishing, advertising, or software development.
Conclusion
Converting inches to pixels ensures your designs, prints, and digital assets maintain their intended size and quality across all devices and mediums. Use this calculator anytime you need fast, precise conversion to avoid costly printing mistakes or poorly rendered graphics.
