Viewing Distance (m)Īnd here’s a handy image showing commong viewing distances and DPIs with a human for scale: Here’s a handy table for determining what DPI to use for common viewing distances Min. Of course, there is a lot of room for variation - for example text might require higher DPI settings than photos, because there are more small details in text than in photographs. Billboards are typically made at between 10 and 50 DPI.
If you’re viewing it from very far away, like a large poster or billboard, then you can get away with a low DPI. Magazines are typically printed at 300 DPI (actually magazines typically use halftone screens, with 150 LPI, but that’s another story!). If you’re viewing something very close up, you’ll need a high DPI for it to appear sharp and not see any pixellation, like in a magazine or book. The main thing to take into account is the viewing distance. (Printing on fabric has it’s own limitations, and so printing using a higher resolution/ DPI image won’t necessarily increase the printed resolution). What DPI you should aim for depends on what the end use of your print will be.įor most applications, especially on printed fabric, 180DPI is more than enough for most purposes and will serve you well. DPI and Viewing Distance - What DPI should I choose? If an image has a resolution of 72 ppi and is 2 inches by 2 inches in size (like the saffron flowers in the top illustration), then we can calculate its. You can just enter in the DPI and the measurements, and it will create a document at the correct size.

Most image editing software will do this all for you: If you wanted your image to be 10 inches wide, and wanted it to be sharp from distances of 3 feet, then your image would need to be 1800 pixels wide. Generally, when making an image for print, you’ll want to think in terms of real measurements (cm, m, inches, etc) and DPI or PPI, which we can use interchangeably for our purposes. Generally, the higher the DPI, the higher resolution the image and the more detail will be in the final print. Ratios are also often used when one needs to calculate the aspect ratio of an image or video, for scaling maps or models. In many cases (though this isnt always true) two objects with the same.

DPI and Viewing Distance - What DPI should I choose?ĭPI stands for ‘Dots Per Inch’ and describes how many pixels there should be per inch when the image is printed. If a ratio is given as 4:12, the GCD of 4 and 12 is 4, so we divide each side by 4 to get 1:4, which is the most convenient form of the ratio to use. This is partly because TV usually has an aspect ratio 16:9, whereas films in cinemas will have an aspect ratio of 1.85:1.Fabric HOT Print Your Designs on 30+ Fabrics Create Now.
