Explaining DPI (Dots Per Inch) and printing

Explaining DPI (Dots Per Inch)

So often we see that we are asked to provide an image for a competition at certain pixel dimensions and at 72dpi, or maybe some other image at 300dpi. What does this mean, what is it all about?

Affinity, who make Photoshop equivalent software, have produced an excellent online article “Understanding DPI”. Give it a look:

It is quite technical in places, but that is the nature of the beast. Overall, though, it gives a good insight into this topic. And it concludes with a comforting paragraph:

“Perhaps the most useful advice when it comes to digital content is… don’t worry too much about DPI! Focus on your pixel resolution, as that ultimately dictates the detail and clarity of your images. DPI alone does not dictate the resolution of your image: it is however used to calculate the ‘physical’ size of your image for print.”
