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? You can just enter in the DPI and the measurements, and it will create a document at the correct size. PRINT RESOLUTION CALCULATOR SOFTWAREMost 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.

Use your image processor program to check what your image’s resolution, or dots per inch, is if you intend to print your image out. The height or width of your image in pixels is not the whole story. This will result in pixellation if you scale it too large. Scaling an image larger will make the individual pixels of that image larger, as well. If you entered a future height or width, the percentage needed to scale to that size will be displayed. If you entered a percentage, the new height or width will be displayed. Either enter a percentage that you wish to scale the image to, or enter the final size you wish your image to be in height, width, or both.Īfter submitting your figures, your calculations will display on the screen. Enter the height and/or width of the image you need to scale.Ģ. This calculator allows you to enter the following components:ġ.

If you use an image that’s too large for the space it’s in, it will result in unsightly aliasing, or jagged looking edges. That means it’s important to use the correct size if, for instance, you are scaling an image for use on a web page. Each pixel is like a building block of an image these building blocks are the base unit that make up what you see in a picture.
