The Short Answer
300 DPI is ideal. 150 DPI is the minimum. Anything below 150 DPI will look blurry when printed.
What is DPI?
DPI stands for “dots per inch.” It tells the printer how many dots of ink to lay down per inch of your design. More dots = sharper image. Fewer dots = pixelated and blurry.
Think of it like this: a 1000×1000 pixel image at 300 DPI prints at about 3.3 inches. The same image at 72 DPI prints at about 13.9 inches — but it’ll look terrible because those pixels are being stretched across a much larger area.
How DPI Affects Your Price
DPI directly affects the print size of your design, which determines your price. Here’s how the same 3000×3000 pixel file prints at different DPIs:
- 300 DPI → 10 x 10 inches → crisp, sharp print
- 150 DPI → 20 x 20 inches → acceptable quality, larger size, higher price
- 72 DPI → 41.7 x 41.7 inches → poor quality, huge size, expensive
If your file has low DPI but you only need a small print, you may be overpaying because the system calculates a larger print area than you actually need.
How to Check Your File’s DPI
Photoshop: Image → Image Size → Resolution field shows DPI.
Our uploader: Just upload your file — we detect the DPI automatically and show it in the file details. You’ll see the exact print dimensions and price before you add to cart.
How to Change DPI
In Photoshop: Image → Image Size → uncheck “Resample” → change Resolution to 300. This won’t change the pixel count — it just tells the printer to print it at the correct size.
Important: don’t just type 300 DPI into a 72 DPI file with “Resample” checked. That upscales the pixels and makes the image blurry. Change DPI without resampling.
Bottom Line
Design at 300 DPI from the start. If you’re working with an existing file, check the DPI before uploading. Our system will show you exactly what you’ll get.
