Work out exactly how many pixels your clipart needs to print crisp at 300 DPI, or flip it around to see the biggest sharp print your current pixels allow. It runs in your browser, no signup.

Pixels you need at 300 DPI

If your clipart is smaller than this, it has to be upscaled to print crisp at 12 × 12 inches. Just changing the DPI label will not add the pixels.

How the 300 DPI maths works

DPI means dots (pixels) per inch, so the pixels you need always depend on the size you print. The formula is simple: pixels = inches × DPI. At 300 DPI a 12 inch print needs 3,600 pixels on that side. The catch sellers miss is that the DPI label on a file does not add pixels. If the pixels are not there at your print size, the image has to be upscaled, not just relabelled.

Common questions

How many pixels is 300 DPI?
It depends on the print size, because DPI is pixels per inch. Multiply the print size in inches by 300. A 12 inch print needs 3,600 pixels on that side, a 6 inch print needs 1,800.
How do I convert inches to pixels at 300 DPI?
Pixels = inches x DPI. So at 300 DPI, an 8 x 10 inch print needs 2,400 x 3,000 pixels. Use the calculator above to do it for any size.
Does changing a file to 300 DPI make it print better?
No. The DPI tag is just a label. What decides print sharpness is the actual pixel count at the size you print. If the pixels are not there, you have to upscale, not just relabel the file to 300 DPI.
What size should clipart be for print?
For most clipart, aim for at least 3,600 pixels on the long side, which is a crisp 12 inch print at 300 DPI. Wall art and large POD items need more.
