Why is 400 dpi so Popular? Massive Explanation

Mice are the most popular input devices for computers. This device is used for pointing to the screen and executing commands. The primary purpose of a computer mouse is for pointing to the screen and also for executing actions. This electronic device is generally connected to computers, laptops, and other devices like MacBooks, notebooks, Xbox, and PlayStations via a USB port. The most popular mice generally come with a 400 dpi (dots per inch) rating, but this rating is not proportional to the performance of the device.

The dpi (dots per inch) measurement is used to rate the quality of the sensor of a mouse. This measurement shows how sensitive the sensor is, and it can greatly affect how long your mouse will work before quitting on you. We use a 400 dpi because it has a great average and it is a good choice for most people as well the pro players too. This article recommends 400 dpi for people who are willing to buy a mouse, keep on reading if you want to learn more about 400dpi and why is it good.

What is DPI?

DPI can either stand for “dots per inch” or counts “per inch”. Which one you’re referring to comes down to the specifics of what kind of device you’re using. In this case, we’ll be discussing how both relate to computer mice, like the exact measurements between the two, and why it matters to use a mouse with a good DPI rate. Let’s get started by taking a brief look at the difference between CPI and DPI.

DPI specifically refers to the measurement of the mouse cursor’s sensitivity over and within specific programs, in terms of its speed. For example, if you were to move your mouse an inch or two across your desktop with a low DPI setting on your device, then move it an extra inch or two across your desktop with a higher DPI setting on your equipment, the cursor would end up moving further in the second example with relatively the same distance covered by sensors on the object moving across clothing. This may be confusing at first because it’s easy to assume that a higher DPI means that more distance is covered but this isn’t exactly the case.

While it is true that DPI is a measurement of the physical relationship only, and that DPIs are associated with sensor precision and accuracy, in no way can one extrapolate this information to deduce “mouse precision”, or the mouse’s cursor speed or responsiveness?

The DPI (dots per inch) of a mouse at its lowest input delay should be 400 DPI as this allows your computer to easily and quickly determine how far you’ve moved the mouse by how many diagonal pixels it crossed on your screen (400 x 2 = 800). Too much variation is not recommended because it takes longer for the computer to calculate the number of diagonal pixels that have been covered. For example, if you were using 1000DPI, it would take more work to calculate the number of pixels than translating movement from a lower DPI such as 400DPI.

While your ideas on pixel skipping/angle snapping are partially right, we beg to disagree with you just as much. There are two separate things that one needs to think about when it comes down to sensitivity – the frame you’re playing with and the frame being played by your mouse. Your frame and mouse frame will never be perfectly in sync but there are ways around this called controller acceleration that people tend to use at low sensitivities so you never really notice the difference between frames because the game automatically speeds up for you for those high sensitivity players. Though this does make it harder for people who have low sensitivities, we recommend most people to lower their speed as much as possible if they main hit scans, because there can be a lot of things happening on screen at any given time that may cause unnecessary deaths if you’re not careful or on top of things.

Is 400DPI  The Best DPI:

400DPI is the DPI most professionals use and what I personally recommend starting off with too. You see, there are only a select few out of millions of people who play mice with 400Dpi and they all happen to be exceptional aimers. Examples would be Dafran, AimbotCalvin, Shroud, S1mple, ScreamGaleadelade, Eomzo, etc. The one thing that all these pro gamers have in common is their insane aim skill and their use of the 400DPI DPI setting.

How much is 400 DPI?

“Dots per inch” is actually a term used to describe the number of pixels displayed per inch on your monitor or screen. It’s called “dpi” because that’s how the resolution is measured.”

400 DPIs = 1 inch of mouse movement. A lower DPI means the cursor moves less distance when you move the mouse.

Why do pros use 400 DPI?

The answer to your question is really simple: The Pro players use those settings because of their mice. They grew up enjoying the accuracy and smoothness of Microsoft’s IntelliMouse or the Logitech Wheel Mouse Optical, both mice that are capable of 400dpi tracking. These players learned how to play with those mice, and so they got used to playing in these settings.

In some games, a higher DPI is more effective than in others. For pro gamers, 400-800 DPI is a minimum to have more control over their characters’ movements. As the DPI increases for various games, it requires less movement per turn to achieve the same result on the screen, which can be advantageous as it decreases the margin of error in the gameplay at higher responsiveness levels.

Should I switch to 400 DPI?

If a player moves their mouse by 400 pixels, 1 inch at a time with his mouse at 400 DPI and acceleration set to disabled for example on Windows 7, the crosshair would move exactly 400 pixels. It’s accurate enough for 99% of players out there, but some will prefer to have higher DPI settings enabled because they may feel the need to be more accurate when playing CSGO.

Why High DPI?

When looking at computer mice you may sometimes see higher DPI (dots per inch) advertised as a desirable trait. However, this is not always necessarily the case and in many cases, you’ll get better results with a standard rating of DPI. Especially if you will be using your computer mouse for graphics intense activities like drawing, photo editing, or 3D design work. Those who primarily use their computer mouse for gameplay may find it more beneficial to have an option that allows them to change between different DPI settings based on whatever the situation calls for. In either case, having the option to choose from a variety of DPI ratings is usually beneficial overall.

For example, A higher DPI would come in handy for business owners who work with many customers each day and have trouble remembering all of their names. This could save these executives significant time if their DPI was set high enough to let them recognize their clients more easily. So, if you are looking to draft a design in a professional program and need the precision that comes with the use of your computer mouse, then working with a higher DPI might be more fitting for you. However, if you’re using your computer mouse more casually to navigate around the internet or draw something in Paint (we all do it), then moving down from something like 2000 DPI to somewhere more convenient like 1000 DPI might be more suitable as most people don’t really work anywhere near as precisely as they often think.

DPI & Sensitivity:

Your mouse’s sensitivity is based on how quickly you are moving your mouse across the desk, so it may seem like increasing the DPI would increase your sensitivity. In fact, DPI does not affect your sensitivity in any way. Increasing DPI only increases how sensitive the cursor becomes to your movements.

You can have low DPI and high sensitivity as well as vice versa. For most purposes, cranking up the sensitivity on a low-DPI mouse isn’t an ideal solution. If your mouse has low DPI with great overall performance, it’s recommended to not add more sensitivity when issues arise such as herky-jerky performance in the way you move quickly across the screen or making detailed edits in a design program. You might be able to zoom in to get some of those details done effectively but essentially you only want to rely on what your equipment offers, not rely on additional software/hardware solutions that could potentially cause more harm than good.

How to check mouse DPI?

Want to know how sensitive your mouse is? There are a few ways to find out: Smaller DPI means increased sensitivity. If a mouse has a smaller figure for its DPI value, that means it is less sensitive. The DPI of a computer mouse determines how far the cursor will move on the screen when you move the mouse the same distance. The sensitivity of the cursor can be adjusted by determining what the user’s desired DPI settings will be.

There is a problem if your game and are a software engineer, though this article isn’t going to get into the debate of whether lower or higher DPI (dots per inch) settings are best. Games often let players use higher DPI settings while having a lower sensitivity so that they move the mouse the same distance: this is useful if you’re changing your mouse or playing a different game and don’t want to have to relearn that muscle memory for rotating 360° for example. There is even an online calculator that can translate between setting from one game to another.

There are many gaming mice that have buttons for switching DPI on the fly and that’s really neat to be able to do that when you’re playing your favorite game, but what if it’s difficult for you to find out or tell what DPI your mouse is currently switched over to when you aren’t even in the middle of a game? Well, we have a few tips for you about how to figure out the DPI of your mouse.

1. Check The Specifications

The easiest and most obvious thing you can do is search online for your make and model. In some cases, you’ll find a specification sheet that displays the mouse’s DPI figure alongside technical details, but as most manufacturers include only the highest DPI setting, you may have to rely on reviews or other customers’ comments if it isn’t specified in any official literature you have at hand.

2. Install the drivers

Again, unless you have an unbranded mouse that relies solely on Windows’s stock driver and does not have a software suite of its own, you should be able to download the appropriate software from the manufacturer’s website. Most manufacturers provide the user’s with more options than Windows itself does including the ability to change what all the buttons do, and – relevant here – choose what DPI setting you want.

When you install the drivers for your mouse, the program usually gives you access to additional features and settings in a standalone app. The DPI setting is commonly located in Settings > Options or Customization > DPI settings.

For example: In Logitech’s Gaming Software. the icon you’ll see a mouse pointer and cog. Usually, a gaming mouse can have up to 5 different DPI levels or sensitivities, but it only has 3 LEDs to indicate what level is selected. Not only that, but the actual DPI settings on each level can be customized – which makes it a common feature on most gaming mice.

How do I change my mouse DPI and sensitivity?

It is commonly known that more expensive mice will be able to change their DPI settings by pressing buttons located either directly on the mouse, or on a software interface provided by a manufacturer. However, casual users may come across this feature in more affordable products offering a variety of extra features. Regardless of what mouse you own, you should always make sure it suits your needs, and this is especially true regarding its precision capabilities. Most mice have software available which allows the user to determine how sensitive the pointer will be – simply open up such settings from within your control panel. There you should be able to manually specify an exact DPI setting if your mouse even has such settings or if it has buttons that can toggle between various DPI settings.

For any users who don’t have dedicated programs, you may want to speed up your mouse cursor with the options detailed earlier (Control Panel/System and Devices/Mouse) or you can use Windows 10 Settings app and click Devices > Mouse where there is a Cursor Speed slider that will do the same thing. If your current mouse isn’t doing it for you, try one of these excellent gaming mice – mouse are by far the most important peripheral when it comes to gaming.


You will have a better understanding of why 400 dpi is so popular after reading this article. For many years it was the standard dpi resolution and a part of the standard video card resolution. Today we have a much higher dpi resolution and a much higher standard video card resolution. But many people still run their mice at 400 dpi. The reason for this is that many games and many professional applications are designed for this dpi resolution. The program then automatically scales the mouse cursor to fit the screen. This is the reason why the mouse cursor is so accurate when you use a 400 dpi mouse. It is also the reason why you have to adjust the mouse speed in many games.
