Even the best computer mouse is useless if you don’t understand its inner workings or have basic knowledge about it. Asking, “What is DPI?” is a great starting point to begin expanding your knowledge. Today, we’ll go over what DPI stands for, what it is, and why it’s essential for everything from the average mouse to the best gaming mouse.


  • DPI stands for Dots Per Inch. It is a physical measurement system used by mice to judge distance and move the mouse cursor accordingly.
  • Whether you should use high or low DPI depends on the project you’re working on. High-precision work calls for a lower DPI.
  • On some mice, there is an option to change the DPI. You should be able to use a physical button on your mouse or a separate program.

Explaining Dots Per Inch (DPI)

DPI stands for Dots Per Inch. It is a physical measurement system used by your mouse to calculate distance during movement. While this may seem complicated, it’s pretty simple. Let’s say you have an average mouse that moves a couple of inches across the video display. If you’re using a high-DPI mouse, moving it a couple of inches will cause the mouse cursor to move further across the screen even though both mice moved the same physical distance. You should know certain things if you use a computer, like how long computer mice last or what an ergonomic mouse is.

Insider Tip

A high-quality wireless mouse should have the option to change DPI settings.

Should I Use High- or Low- DPI?

You’ll find that DPI is important for several reasons. The biggest is that its part of what dictates mouse movement. You’ll find that high DPI is excellent if you’re moving your mouse across your screen regularly and don’t require a lot of precision. On the other hand, you might want a lower DPI for more precise work, such as editing photos or documents. Asking, “What is a mouse sensor?” or “What is a mousepad?” will help you better understand the inner components of mice.

How to Change DPI

Whether or not you can change DPI will depend on your mouse. Some of them will have a physical button you’re able to press to cycle through different DPI profiles. For others, there might be a program on your computer you have to use that might also have additional mouse options.
