In physical terms, that’s a whopping 56 inches by 42 inches. (It can also require some monkeying around with HTML, which many web-hosting sites and web-design apps help with.)Ī photo taken by some recent vintage iPhones are 4032×3024 pixels and marked as 72 dpi in the file.
In order for interface elements and images alike to appear to their best advantage on smaller devices, creating high-density versions requires a lot of resolution. Smaller devices typically have higher ppi because you hold them closer monitors have lower ppi for the same reason. The ppi varies by display size, because it’s based on how closely your eye is to the screen for reading. The density started to increase dramatically, and now displays with 200 to 450 ppi are common, including Apple’s branded Retina displays. At one time not that long ago, most displays were 72 dpi or 96 dpi.
They are both measures of resolution, but ppi is related to your screen while dpi is about your printer.A higher dpi is required for higher-density displays. To be even more confusing, I used ppi (pixels per inch) interchangeably with dpi (dots per inch), which most people do. If you double your page size before exporting an image of the slide, you will have doubled the ppi/dpi. Another way to get the same effect is with page layout. So basically you can just save your slide as an image and adjust the pixel dimensions of the output (save as picture > options >. So, for example, if you’re image is 100 pixels * 200 pixels and you print it 1 inch by 2 inch, your resolution will be 100 ppi (pixels per inch), but if you print the image 2 inches by 4 inches, it’s only a resolution of 50 ppi. When you save a slide, keep in mind you’re saving an image file (e.g., jpg, gif) and not necessarily a particular size to print or display. But if you mean a vector graphic (e.g., a slide you created by using the text, shapes, etc within ppt), you can have any resolution. If you mean a drawing/photo that’s in a ppt, you’re unfortunately limited to the resolution of the original image.
