Look back up again at the three original kitties – their size doesn’t change at all on your screen, because your screen understands one measurement: pixels. So, how does this relate to the web, again? One is at 72 DPI, one is at 300 DPI, and one is at 1000 DPI:Īhhh, so image DPI does matter… but only if you’re printing it out. Now, let me show you three images from Placekitten, aka the best site ever. Let’s think of them interchangeably for our purposes. They’re quite similar, and people often use them interchangeably, which is a little confusing, so don’t worry about it for now. The term DPI is generally used for printed images since printed images are made up of tiny dots, while the term PPI is mostly used for screens, since screens contain pixels. If you’re sitting here thinking “WTF is DPI?” or “Is DPI the same as PPI?” or “Why, oh why, are there so many acronyms in the world?”, DPI stands for “dots per inch”, and PPI stands for “pixels per inch”. Friends, I’m here to put the 72 DPI myth to rest. As in, “images for the web should be 72 DPI while images for print should be at least 300 DPI”. If you’ve ever had to communicate with someone about creating/resizing images for the web, I’ll bet you’ve heard a lot about “72 DPI”.
