PIXELS ↔ INCHES ↔ CENTIMETERS
Pixels to Print Size Calculator
Convert pixel dimensions to inches and centimeters at any PPI—or calculate exactly how many pixels you need for a target print size.

THE FORMULA
How pixels become print dimensions
inches = pixels ÷ PPIpixels needed = inches × PPI
A 3,000-pixel-wide image printed at 300 pixels per inch is 10 inches wide. The same image at 150 PPI is 20 inches wide, but each inch contains fewer pixels.
For a detailed check of an actual file, including embedded resolution metadata, use the DPI/PPI Checker.
CHOOSING A RESOLUTION
What PPI should you use?
300 PPI: A common target for high-quality photographs and artwork viewed up close.
240 PPI: Very good quality for many photo prints, with a little more physical size from the same pixels.
150 PPI: Often suitable for posters and larger prints that are normally viewed from farther away.
The right value depends on the image, printing process, viewing distance, and your quality expectations.
For a screen or website, the image's pixel width and height matter; a 72 or 96 PPI metadata label does not control how many pixels the screen displays.
Confused by a file labeled 72 or 300 DPI? The DPI vs PPI guide shows why the label can disagree with the effective PPI at your intended print size.
QUICK REFERENCE
How many inches is a pixel width?
There is no single inches value for a pixel count: physical width changes with your chosen PPI. The table shows one edge of an image, not the size of a complete print. Use the calculator above for both width and height.
| Image width | At 300 PPI | At 150 PPI |
|---|---|---|
| 1,000 pixels | 3.33 inches | 6.67 inches |
| 1,920 pixels | 6.4 inches | 12.8 inches |
| 3,000 pixels | 10 inches | 20 inches |
| 4,000 pixels | 13.33 inches | 26.67 inches |
For example, a 3,000 × 2,000 pixel image at 300 PPI spans 10 × 6.67 inches. These are arithmetic results, not a promise that the image itself is sharp. A blurry or heavily compressed source can look poor even at 300 PPI.
If the image and desired print have different proportions, you may need to crop before printing. A crop uses fewer source pixels, so check the final cropped file in the calculator. For common full print sizes, see the pixel requirements chart.
COMMON QUESTIONS
Print-size FAQ
How do I convert pixels to inches?
Divide each pixel dimension by the intended PPI. For example, 3,000 pixels divided by 300 PPI equals 10 inches.
How many inches is 1000 pixels?
It depends on print density. At 300 PPI, 1,000 pixels span about 3.33 inches. At 150 PPI, the same pixels span about 6.67 inches. Check the image's other edge too before choosing a print size.
How many pixels do I need for an 8 × 10 print?
At 300 PPI, you need 2,400 × 3,000 pixels. At 240 PPI, you need 1,920 × 2,400 pixels. At 150 PPI, you need 1,200 × 1,500 pixels.
Does a higher PPI make a smaller print?
Yes, when pixel dimensions stay fixed. Packing more pixels into every inch creates a smaller physical print with denser image information.
