If your website page is, for example, 1000 pixels wide, and you want to fill exactly half that width with an image, well, that image should be 500 pixels wide (how many of those pixels might be in an inch or a centimeter is a meaningless concept).Īlso, back to vector imagery. In HTML, for example, images are defined by their pixel dimensions, not the number of pixels per inch. Instead you should be thinking in terms of how many pixels you need to fill the space. Fixed linear measurements, like inches, pertain to physical objects in the real world that don’t change size (like a sheet of paper), whereas a digital image displayed on a monitor might be an inch wide on one monitor and only three quarters of an inch wide on the next. When it comes to digital displays, you shouldn’t be thinking in terms of how many pixels are in an inch since it’s, well, meaningless. Even then, though, it was a meaningless concept when preparing graphics for digital use. Old Macintosh monitors from 20 years ago used that resolution, but modern displays are much higher resolution. The 72ppi rule for digital displays is also wrong, misguided and should be immediately forgotten as though you never heard it. Instead, you let it remain as vector art to be rasterized at the maximum resolution of the output device, which is often thousands of dots per inch. I understand that I would be needing a 300ppi and 72ppi resolution respectively.įor print, as PrintDriver mentioned, you do not rasterize the vector work done in illustrator to a fixed resolution. ![]()
