DPI primarily means how many dots (or virtual pixels) can be detected and read by the mouse when it is being used. It is one of the standards used to measure and market mice out to the public. It can be compared to a car’s RPM. A car running at 4000 RPM means its engine will be faster as compared to a car currently in 2000 RPM.
What is the Difference between DPI and CPI?
CPI refers to Counts Per Inch and it relates how many virtual pixels the mouse sensor can pick up with the onboard sensor. Many people confuse both of the metrics but they essentially mean the same thing. It is just a matter of preference. Some manufacturers might choose to measure their mouse using DPI while some might use CPI.
How do I Check my Mouse DPI/CPI?
There is no specific application or setting in Windows operating system which allows you to see the exact number on what your mouse’s DPI or CPI. The metric is usually specified in the documentation or specifications of your mouse model. There are two ways you can essentially measure your mouse’s DPI/CPI.
Method 1: Checking Specification
The most accurate method to check your mouse’s CPI/DPI is to look up its specification and see the metric documented by the manufacturer itself. DPI/CPI needs accurate measurement which may be calculated by you (as in the second method) but it will not be in any way accurate. So navigate to your manufacturer’s website and look up your mouse’s model. Once the product page is opened, you need to locate the section where all the information is stored. As in the picture above, the CPI for Bloody J95 is 5000 (adjustable). It will probably be in front of the tag resolution.
Method 2: Measuring DPI/CPI
If you cannot find the specification online of your mouse model, you can try measuring the DPI/CPI manually. This method will not be accurate so you will have to take averages. Furthermore, we will also disable a specific setting in Windows OS which manipulates the CPI/DPI of your mouse so we can get accurate readings. You will need a ruler, a white paper, and a marker.
Like we mentioned earlier, this method may not give accurate readings so it is better than you look for the manufacturer specifications.
What is my Current DPI of an Adjustable DPI Mouse?
If you have a high-end mouse which allows you to change the DPI settings, you can find the current DPI by its software. Companies such as Bloody or Razer have dedicated software which allows users to control the DPI of their mouse and monitor in real time. As you can see at the image above, the DPI is set to the maximum which you can change easily using the CPI options.
