Pixel to Inches Converter
Frequently Asked Questions
What DPI should I use for converting pixels to inches for print?
Use 300 DPI for professional print quality such as business cards, brochures, and photos. Use 150 DPI for large-format prints viewed from a distance like posters and banners. Web and screen designs typically use 72 or 96 PPI. Always confirm requirements with your print vendor before finalizing.
How many pixels is 1 inch at 96 DPI?
At 96 DPI, which is the default resolution for Windows screens, 1 inch equals exactly 96 pixels. This is also the standard reference value used in CSS, where 1 inch is defined as 96 CSS pixels regardless of the actual physical screen density of the device being used.
Why does the same image look different sizes on different screens?
Because different screens have different PPI values. A 500-pixel image on a 96 PPI monitor appears 5.2 inches wide, but on a 227 PPI Retina MacBook screen it appears only 2.2 inches wide. Physical size depends on both the pixel count and the screen's pixel density in pixels per inch.
How do I find the PPI of my monitor?
Divide your screen's horizontal resolution by its physical width in inches. For example, a 1920-pixel-wide monitor with a 20-inch physical width has a PPI of 96. You can also search your monitor model online to find the manufacturer-specified PPI or use a dedicated PPI calculator tool.
Is there a difference between DPI and PPI for this conversion?
Mathematically, no — the conversion formula Inches = Pixels ÷ DPI is identical whether you use DPI or PPI. The terms differ in context: PPI describes screen density while DPI describes printer output. Both represent how many dots or pixels fit into one physical inch, making them interchangeable in conversion calculations.
