What is DPI? What does it mean if my image is low DPI?

DPI stands for dots per inch and refers to the ink dots per inch when an image is printed. The DPI value depends on the size that the image is being printed, so a digital image on its own has no DPI. 

You can find out a print's DPI by using this calculation: Width in pixels of the long side of the image, divided by inches of the long side of the print

For example, if your image is 1200 x 800px and you print it as a 4x6, you would divide 1200 (the long side of the image) by 6 (the long side of the print) to get a DPI of 200. If you print this same image as a 2x3, the DPI would be 400. 

Low DPI Warning

To prevent a pixelated print, we recommend 120 DPI or higher for each image. If an image in a lab-fulfilled order has a DPI lower than 120, we will show a low DPI warning next to the given image.

To remove this warning, you either need to:

• Replace the image with a larger version by clicking the Replace Image button under the image thumbnail on the left side of the screen

• Select a smaller print size by clicking Edit Item 

Keep in mind that cropping in on an image will also lower the DPI.
