That’s everything there is to know about how to change DPI in GIMP, as well as a bit of extra technical knowledge for your own personal edification.

So while it’s useful to know that standard screen resolution for an image file is typically considered to be 72 DPI, that doesn’t really correlate to how your image is actually displayed on a monitor, and there are quite a number of other variables that it’s impossible to account for. But if I used the same QuadHD resolution on a 24” monitor, the DPI would be even higher.
My PC monitor is a 27” monitor using the QuadHD resolution of 2560×1440, which actually works out to 109 DPI. In the early days of desktop publishing (long enough ago that it was still called that), the idea was fairly simple because screen resolution was primarily limited by the technical capabilities of the time.Īpple’s controlled hardware ecosystem gave us the most common standard explanation that screen resolution is 72 DPI – but that was chosen because their best printer at the time, the Apple ImageWriter, was capable of 144 DPI output, exactly twice the screen resolution – which is considered low by today’s standards.īut in a world of high-resolution monitors and high-DPI smartphones, the idea gets much more confusing. 300 DPI is considered the standard print resolution, while screen resolutions are usually closer to 100 DPI, ranging from 72 to 109 or even higher, depending on the device.

Just enter the new resolution into the X resolution box, and the Y resolution box will update as long as the two are linked. With your image loaded and ready in GIMP, open the Image menu and click Scale Image. Here’s how (and why) to change DPI!

Use this converter to estimate the size of an image file as you adjust the on-screen image size (in pixels), bit depth (8 bits per byte) and printed dots per inch (dpi). If you want a bit more of an explanation of the process, read on! The Detailed Guide to Change DPI in GIMP If you’re already familiar with image editing concepts and just needed to know where to look for the resolution options, you’ll have everything you need.
