Print Size Formula:
| From: | To: |
Pixel to print size calculation converts digital image dimensions (in pixels) to physical print dimensions (in inches) based on the printer's resolution (PPI - pixels per inch). This helps determine how large an image can be printed while maintaining quality.
The calculator uses the formula:
Where:
Explanation: The formula divides the digital pixel count by the printer's resolution to determine the physical size of the printed image.
Details: Calculating print size is essential for photographers, designers, and printers to ensure images maintain quality when printed at specific sizes. Higher PPI values result in smaller but sharper prints, while lower PPI values produce larger but potentially pixelated prints.
Tips: Enter the number of pixels in your image and the desired PPI (pixels per inch) for printing. Common PPI values are 300 for high-quality prints, 150 for standard quality, and 72 for web graphics.
Q1: What is the difference between PPI and DPI?
A: PPI (pixels per inch) refers to digital image resolution, while DPI (dots per inch) refers to printer resolution. They are often used interchangeably but technically measure different things.
Q2: What PPI should I use for high-quality prints?
A: 300 PPI is generally recommended for high-quality photographic prints where fine detail is important.
Q3: Can I print larger than the calculated size?
A: Yes, but the image may appear pixelated or soft if printed significantly larger than the recommended size for your chosen PPI.
Q4: How does this affect image quality?
A: Higher PPI values mean more pixels are packed into each inch, resulting in sharper, more detailed prints. Lower PPI values spread fewer pixels across more space, potentially reducing quality.
Q5: Should I use the same PPI for width and height?
A: Yes, PPI is consistent across both dimensions. You'll need to calculate print size separately for width and height if your image isn't square.
