It’s our natural tendency to have curiosity to know the functionality and the fancy terms associated with the gadgets we use on a daily basis. Take the computer mouse, for example; CPI is a term that is not used quite often in the product description.
So, what is CPI in the mouse?
CPI stands for “Counts Per Inch”. It defines how many pixels your cursor moves on the screen when you move your mouse one inch on your mousepad or desk.
Often, the terms DPI and CPI are used interchangeably, but it’s worth noting that CPI is a more accurate and precise measurement compared to DPI. While these terms may sound technical, they both play a role in influencing the precision of mouse movements and gaming preferences.
Difference Between CPI and DPI
Both CPI and DPI play a crucial role in understanding the sensitivity of a computer mouse. DPI, or “Dots Per Inch”, measures how sensitive a mouse is, with a higher DPI resulting in increased sensitivity.
The term refers to the number of pixels the cursor moves through for each inch the mouse travels across the screen. For example, a mouse set at 800 DPI will move the cursor 800 pixels per inch.
Higher-end mice often offer customizable DPI settings, allowing users to tailor sensitivity based on their preferences.
On the other hand, CPI, or “Counts Per Inch”, is a term used interchangeably with DPI in the context of gaming mice. It denotes a mouse’s sensitivity, with a higher CPI indicating greater sensitivity.
Similar to DPI, a lower CPI means the mouse moves more slowly, requiring more physical movement to traverse the screen. Conversely, a higher CPI means less movement is needed.
In essence, understanding either DPI or CPI provides insights into a mouse’s sensitivity, influencing cursor movement and catering to individual preferences, especially in the realm of gaming where precision is key.
How To Test CPI?
There are different ways of finding the CPI of your mouse. You can check the product specification on the package or in the manufacturer’s website. There are also many tools like DPI analyzer and Mouse sensitivity for checking the mouse CPI.
If you are unable to track the CPI of your mouse from any method, here is a simple trick to measure it without visiting or installing any tool.
For this, you need to mark 1 inch distance on your mouse pad or desk surface.
Open the MS Paint application.
Make sure the canvas is at 100%.
Track the indicated number as indicated. It is better to mark the distance horizontally on your mouse pad or desk and track the pixel count indicated on the left.
Make sure the initial count should be at 0.
As you move your mouse the numbers will change accordingly. Move your mouse to 1 inch as marked on your desk and note the number.
Repeat this process as many times as you want and draw an average value out of that.
That value is the approximate CPI of your mouse.
How Do I Adjust My Mouse CPI?
CPI is not a common setting that is available in all mice. So, changing this setting is not possible in every type of mouse.
Modern gaming mice often feature a button to adjust the CPI, allowing you to switch between different sensitivity levels during gameplay.
Some manufacturers also provide dedicated software to customise different settings in the mouse including the CPI. These settings allow the user to fine-tune the response of the mouse with optimal accuracy, control, and comfort.
Is CPI Important For Gaming?
Absolutely! CPI is an important factor in gaming. In the context of gaming mice, CPI determines how quickly the cursor moves on the screen in response to physical mouse movement.
A higher CPI means increased sensitivity, allowing for faster and more precise cursor control. This is particularly vital in gaming scenarios where split-second reactions and accurate aiming can make a significant difference.
Players often have diverse preferences when it comes to sensitivity, and having the ability to customize CPI settings on a gaming mouse provides a tailored experience.
Some gamers prefer lower CPI for precise aiming, especially in first-person shooter games, while others opt for higher CPI for quicker movements in fast-paced games.
The flexibility to adjust CPI settings based on individual playstyles and game genres is a valuable feature for gamers seeking optimal performance.
What Is A Good CPI For A Mouse?
The ideal CPI for a mouse depends on individual preferences and the specific use case, particularly in gaming.
Many professional gamers, especially in FPS games, prefer lower CPI settings between 400 to 800 CPI. This lower sensitivity allows for more precise aiming.
In fast-paced games like MOBAs or RTS games, some might opt for higher CPI settings between 1600 and 3200 CPI, for quick and responsive movements.
Mice with customisable CPI settings are versatile. They allow users to adjust sensitivity on the fly, catering to different scenarios within a game or adapting to various tasks in other applications.
Users with high-resolution monitors might find higher CPI settings more suitable, as it can reduce the need for large hand movements to traverse the screen.
Is More CPI Good Or Bad?
Increasing CPI in a mouse can be both good and bad, depending on the user’s preferences and needs.
Higher CPI settings can provide smoother and more precise cursor movement, which can be beneficial for tasks requiring precision, such as graphic design or gaming.
However, extremely high CPI settings may lead to overshooting the target and reduced accuracy, especially for tasks that require fine control.
You don’t need a high CPI range to perform most of the day-to-day activities, rather you should find a balance that suits your needs and preferences.
Does CPI Impact The Battery Life?
Yes, the CPI setting can impact the battery life of a wireless mouse. Higher CPI settings generally result in increased power consumption as the mouse sensor works at a more sensitive and responsive level.
This heightened sensitivity requires more frequent data transmission between the mouse and the computer, consuming additional energy.

In contrast, lower CPI settings demand less power as the sensitivity decreases, allowing for more conservative use of the mouse’s battery.
Therefore, users who prioritize longer battery life may opt for lower CPI settings when using a wireless mouse.
It’s important to consider this factor when configuring CPI, especially for those who rely on wireless mice in situations where battery longevity is crucial.
