Frequently asked questions
How is the print size calculated?
Print size = pixels ÷ DPI. For example, 3000 pixels at 300 DPI print 10 inches (25.4 cm) wide.
Why are the dimensions swapped for some photos?
Phones often store rotation as an EXIF tag. We show the dimensions as the photo is displayed, after applying the orientation.
Are my images uploaded?
