For example:
- A 3000 × 2400 pixel image at 300 DPI prints at 10" × 8"
- The same image at 150 DPI prints at 20" × 16"
Why Oversized Prints Can Look Blurry
If you try to print a small image at a large size, the printer will stretch the pixels. This creates visible softness or pixelation, especially at close range.
For best results:
- Use 300 DPI for small or mid-size prints
- Use 150–200 DPI for large prints viewed from a distance
- Avoid printing below 100 DPI unless intentionally low-res
Quick Reference Table
| Image Size (pixels) | Sharp Print Size at 300 DPI | Usable at 150 DPI |
|---|
| 1200 × 1800 | 4" × 6" | 8" × 12" |
| 2400 × 3000 | 8" × 10" | 16" × 20" |
| 3600 × 5400 | 12" × 18" | 24" × 36" |
What If Your Image Isn’t Big Enough?
You can:
- Print smaller
- Allow lower DPI if the print will be viewed from a distance
- Upscale the image with care using software like Photoshop or Gigapixel AI
Avoid simply stretching the image without resampling — it will appear blurry.
Summary
To get the best print results:
- Start with a high-resolution image
- Match your desired print size to the image’s pixel dimensions
- Use DPI to calculate how large your photo can print without losing clarity
Understanding how image size and print size relate gives you control — and helps you avoid disappointing results.
