I’m serious about the aspect ratio, by the way you can usually fudge the print quality a bit (paintings are blurrier that photos by default so you don’t need to be as picky), but if your actual width:length ratio is wrong? You may have to make some painful cropping decisions as most print places only carry a specific range of paper sizes.ĭon’t forget to untick ‘Preserve Aspect Ratio’ as that will force your width and height to stay the same relative sizes, so you’ll be stuck in an endless update loop.ĭoes it need to be high quality and detailed? Probably 5000-15,000. When selecting a size, consider the following things:ĭo you need to print it? Calculate the largest size and exact aspect ratio that you’ll need and use that so you don’t have to worry going forward. But you don’t need to worry about that unless you are trying to get a really specific printing result. Print size is an estimate based on your pixel size (the ‘real’ size of the image) and the ‘Pixels/Inch’ measurement (also known as DPI/PPI), which tells the printer how detailed the final image should be. However, the bigger your image, the more memory it uses and the slower things might get (this is why the mobile apps have capped canvas sizes). However, you don’t actually need a very large canvas size if you just want to share your work online. The bigger your image, the more detail you can add, and the larger you can print. Every image on your screen is made up out of many, many little pixel dots, and this is what you are ‘painting’ with.Įvery digital image contains a specific number of pixels, and the size of your canvas is literally just picking how many pixels you want to start with.
