CPI vs DPI – What Sets Them Apart

CPI vs DPI – What Sets Them Apart

When it comes to CPI and DPI, you might be wondering what exactly sets these two measuring units apart. Well, let me break it down for you.

CPI, also known as Counts Per Inch, is a measurement that refers to how many times a mouse can detect movement per inch. It determines the sensitivity of your mouse and is crucial in determining the accuracy and precision of your cursor movements. The higher the CPI value, the more sensitive your mouse becomes, allowing for faster and more precise cursor movements.

On the other hand, DPI, or Dots Per Inch, is a measurement that originated from the printing industry and was later adapted for computer peripherals like mice. DPI, in the context of mice, primarily refers to how many pixels the mouse cursor moves onscreen for each inch of movement on a physical surface. Similar to CPI, a higher DPI setting means the cursor moves more pixels, resulting in faster cursor speed.

Now, you might be thinking, “What’s the difference between the two?” Well, here it is. While CPI relates to the mouse’s built-in sensor, DPI is a software-based adjustable setting. CPI determines the maximum sensitivity of your mouse, while DPI lets you customize and fine-tune the sensitivity levels according to your preference.

In simpler terms, think of CPI as the baseline sensitivity of your mouse, while DPI allows you to increase or decrease that sensitivity within the range set by the CPI value. So, combining both CPI and DPI, you can truly personalize your mouse’s sensitivity to suit your needs, whether you prefer lightning-fast browsing or pixel-perfect accuracy in gaming.

In conclusion, while both CPI and DPI contribute to the overall sensitivity of your mouse, CPI sets the foundation, and DPI builds upon it by providing adjustable sensitivity options. So, when it comes to optimizing your mouse settings, remember that finding the perfect CPI and DPI combination is key to achieving a smooth and precise user experience.

CPI vs DPI - What

If you’re in the market for a new gaming mouse, you might be wondering about DPI and CPI. How exactly do these features impact the performance of a mouse? And will you notice a significant improvement if you get a mouse with 6,000 DPI? Plus, some gaming mice have a CPI switch while others come with a DPI switch. So, what’s the difference between the two?

I understand that all of this can be really confusing, especially if you’re just starting to add special gear to your pro-gaming arsenal. But don’t worry, I’m here to help you figure out which of these two features is more important for your gaming needs. But before we dive into that, let me explain what CPI and DPI actually mean.

Let’s start with CPI or Counts per Inch. This refers to the number of steps a mouse measures as it moves an inch on the mousepad. Basically, CPI shows how sensitive the mouse is or how much it needs to move to reflect the distance a cursor covers on the screen.

For example, if you have an 800 CPI mouse, it sends 800 signals to your system every time it moves an inch. This results in greater sensitivity. Additionally, the sensitivity of a gaming mouse is also described with an eCPI number, which stands for effective CPI.

Now, here’s where it can get a bit complicated. Most games allow you to adjust the in-game mouse sensitivity settings. This is where the eCPI comes into play. It’s a software-based adjustment that doesn’t affect the actual hardware CPI of your mouse. So, let’s say you have an 800 CPI mouse and you set the in-game sensitivity to 2. The resulting eCPI would be 1,600.

I hope this clears things up a bit. Now, let’s move on to discussing DPI and how it relates to gaming mice.

CPI and DPI Disambiguated


Hey there! Ever heard of DPI before? It stands for Dots per Inch and is commonly used in the printing and video/photo industry. Basically, it’s all about how many dots can fit in a straight line within one inch. But you might be wondering, how does this relate to the performance of a gaming mouse?

Well, truth be told, it actually doesn’t. Surprising, right? In fact, DPI has nothing to do with computer mice. It’s just that some mouse manufacturers use the term DPI for marketing purposes because it’s more well-known to the general public. This leads to confusion because people mix up DPI and CPI, using them interchangeably. But, to set the record straight, only CPI is correct when talking about computer mice.

Should You Go Sky High?

Now, let’s talk about those gaming mice that boast high DPI counts, like up to 24,000. Sounds impressive, doesn’t it? However, the reality is a bit different.

The more dots a mouse has to read, the greater the chances of interferences and noise, which can result in errors when the system tries to pick up mouse movement. So, just because a mouse has a super high DPI doesn’t mean it can process more information than one with a lower DPI, like 1,600.

You see, CPI is all about measuring the distance reflected on the screen, not about exactness or precision. It’s something to keep in mind!

Refresh or Polling Rates

Okay, let’s dive into refresh or polling rates. When talking about DPI and CPI for computer mice, you’ll probably come across these terms. They’re measured in Hz and indicate how often your mouse updates the cursor position. The rates range from 125 Hz to 1,000 Hz, so a 1,000 Hz mouse updates the cursor location 1,000 times every second, or once every millisecond.

Now, how does this impact your gaming experience? A higher rate means there’s minimal delay between moving the mouse and seeing the cursor move on the screen. However, keep in mind that a high polling/refresh rate can be demanding on your CPU and use up more processing power than you might be willing to allocate to a mouse.

But here’s the thing, since it all happens in milliseconds, you’re not likely to notice much of a difference between a 500 Hz and 1,000 Hz mouse. Plus, some mice give you the option to adjust the refresh rate, so you can choose the one that suits your gaming preferences.

What’s the Best Choice?

Now, finding the perfect answer to this question isn’t easy because there are so many factors to consider. You’ve got to think about the games you like to play, your PC’s specs, the type of monitor you use, and even the weight of the mouse, just to name a few. In the end, it all comes down to what works best for you. But hey, there are some general guidelines you can follow based on recommendations from the gaming community.

What’s the Best Option

Let’s talk about gaming mice and how they can enhance your gaming experience. If you’re a gamer using a 4K monitor, you’ll want to consider a high CPI mouse. These mice allow for precise movements and fast cursor navigation, which can be really handy. On the other hand, if you enjoy shooter games, lowering the in-game CPI with a high-CPI mouse might actually improve your aiming skills. When it comes to DPI, it’s generally recommended to go for a lower setting in FPS games, but it’s always worth looking at some examples to find what works best for you.

Speaking of FPS games, let’s take Overwatch as an example. While it may not be strictly classified as an FPS game, looking at the mouse settings of professional players can give us some insights. Most Overwatch pros use mice with DPI ratings between 800 and 1,600. However, there are some outliers who prefer to go as low as 400 DPI or as high as 2,000 DPI.

Aim, Click, Kill

All in all, the key to a great gaming experience lies in finding a mouse with a CPI and DPI range between 400 and 1,600 that feels comfortable for you. Ultimately, it’s all about what helps you achieve optimal results and feels good while gaming.
