Pixels to Print Size Calculator
Convert digital image dimensions (pixels) to physical print size. Calculate print dimensions in inches and centimeters based on resolution (DPI/PPI).
300 DPI recommended for high-quality prints
How to Use This Calculator
- Enter your image dimensions in pixels (width and height).
- Enter your desired print resolution in DPI/PPI (300 DPI is standard for high-quality prints).
- The calculator displays the maximum print size in both inches and centimeters.
- Use this to determine if your image resolution is sufficient for your desired print size.
Print Size Formula
Print size is calculated by dividing pixel dimensions by DPI:
Print Height (inches) = Pixel Height ÷ DPI
Print Size (cm) = Print Size (inches) × 2.54
Example: A 3000×2000 pixel image at 300 DPI: Width = 3000 ÷ 300 = 10 inches, Height = 2000 ÷ 300 = 6.67 inches. This equals 25.4 × 16.9 cm.
Full Description
Converting digital image dimensions to physical print size is essential for photographers and designers preparing images for printing. Understanding the relationship between pixels, DPI (dots per inch), and print size helps you ensure your images have sufficient resolution for high-quality prints and prevents pixelation or quality loss.
DPI (or PPI) determines print quality. Higher DPI means more dots per inch, resulting in sharper, more detailed prints. However, higher DPI also means smaller maximum print sizes for a given pixel count. The standard 300 DPI provides excellent quality for most prints viewed up close, while 150-200 DPI is acceptable for large format prints viewed from a distance.
Use this calculator to determine the maximum print size for your images, plan print projects, and ensure you have sufficient resolution before printing. Remember that you can always print larger at lower DPI, but quality will decrease. For best results, aim for 300 DPI for prints viewed up close and adjust based on viewing distance and print size.
Frequently Asked Questions
What DPI should I use for printing?
300 DPI is the standard for high-quality prints viewed up close. 240 DPI is acceptable for most prints. 150 DPI works for large format prints viewed from a distance. 72 DPI is screen/web quality and not recommended for printing.
How do I know if my image is high enough resolution?
Multiply your desired print size (in inches) by your target DPI. For example, an 8×10" print at 300 DPI needs 2400×3000 pixels. If your image is smaller, it may appear pixelated when printed.
Can I print larger than the calculated size?
Yes, but quality will decrease. Printing at lower DPI (150-200) is acceptable for large prints viewed from distance (like posters). For close viewing, stick to 300 DPI for best quality.
What's the difference between DPI and PPI?
PPI (Pixels Per Inch) refers to digital image resolution. DPI (Dots Per Inch) refers to printer output resolution. For practical purposes, they're often used interchangeably, though technically different. This calculator uses DPI/PPI as equivalent.
