Pixels to Inches Converter
Convert image dimensions in pixels to inches using pixels per inch (PPI).
Why Convert Pixels to Inches?
When preparing images for printing, it’s essential to know the physical size your image will occupy on paper. Pixels alone don’t tell the whole story. The PPI (pixels per inch) value determines how many pixels are printed per inch of paper. By dividing the pixel count by the PPI, you can calculate the final print size in inches.
Formula for Conversion
Inches = Pixels ÷ PPI
You need to apply this formula separately for width and height to find the full print dimensions.
Example Calculation
Suppose you have an image that’s 3000 × 2000 pixels and your printer is set to 300 PPI:
Width = 3000 ÷ 300 = 10 inches
Height = 2000 ÷ 300 = 6.67 inches
Your image will print at approximately 10 × 6.7 inches without quality loss.
Recommended PPI for Printing
The print quality depends heavily on the chosen PPI:
| Print Type | Recommended PPI |
|---|---|
| Large Posters | 150 PPI |
| Everyday Printing | 200 PPI |
| High-Quality Photos | 300 PPI |
| Professional Photo Books | 300–600 PPI |
| Fine Art Prints | 600+ PPI |
Factors That Affect Print Size
- Image Resolution: Higher resolution (PPI) prints smaller but sharper.
- Printer Quality: Some printers can handle high PPI but may not need it for large-format prints.
- Viewing Distance: Posters viewed from afar don’t require as high a PPI as close-up photo prints.
- Scaling: Enlarging an image reduces its effective PPI, potentially lowering quality.
FAQs
Can I print a 72 PPI image?
Yes, but it will likely appear blurry or pixelated unless printed at a very large size and viewed from a distance.
Is 300 PPI the standard for all prints?
300 PPI is the standard for high-quality photos, but larger prints can look fine at 150 PPI due to viewing distance.
Can I just increase the PPI in Photoshop?
Increasing PPI without adding actual pixel data doesn’t improve quality. You need a high-resolution original file.
Conclusion
Converting pixels to inches ensures your digital images print at the size and quality you expect. Use the calculator above to determine your print dimensions and make adjustments to resolution or scaling before sending your project to the printer.
