Pixels to Inches Converter
Enter a value in pixels, inches, or centimeters and a DPI (dots per inch) resolution to convert between them. The relationship between pixels and physical size depends entirely on the resolution: at 72 DPI (classic Mac), 100 pixels is about 1.39 inches, while at 300 DPI (print quality), 100 pixels is only 0.33 inches.
This converter is essential for print design, where you need to know how many pixels are required to fill a certain physical size at a given print resolution. It is also useful for screen design (96 DPI is the web standard, 72 DPI is the macOS legacy standard) and understanding how images will appear at different resolutions.
The converter works bidirectionally — enter pixels to get inches/cm, or enter inches/cm to get the required pixel count at your DPI.

Frequently asked questions
What DPI should I use for print?▼
300 DPI is the standard for high-quality printing (photos, magazines, brochures). 150 DPI is acceptable for large-format prints viewed from a distance. 72 DPI is screen resolution and will look pixelated when printed at a normal viewing distance.
What is the standard screen DPI?▼
96 DPI is the default Windows and web standard. 72 DPI was the original Mac standard. Modern Retina/HiDPI displays are 144-220+ DPI physically, but the browser still reports CSS pixels at 96 DPI and doubles the physical pixels.
How many pixels do I need for a 4x6 inch print at 300 DPI?▼
1,200 x 1,800 pixels. Multiply each dimension in inches by the DPI: 4 x 300 = 1,200 and 6 x 300 = 1,800.
