What is DPI & eDPI?

DPI stands for Dots Per Inch, which is a measurement of how many times your mouse reports its position to your PC. eDPI stands for ‘effective Dots Per Inch,’ which is a formula used to calculate the effective sensitivity of any given player, regardless of hardware or software settings. We explain this in depth below.


Note: in PC gaming, CPI (Counts Per Inch) is used intermittently with DPI. 

DPI stands for Dots Per Inch. If you’ve got your mouse set at 1000 DPI it means that the mouse will ‘measure’ 1000 points of movement per inch that you move the mouse. The higher your DPI is the more your cursor moves when you move the mouse, so the higher the DPI, the more ‘sensitive’ the mouse, from a hardware point of view. If your mouse is set to 800 DPI it will travel 800 pixels (‘counts/dots’) on screen per inch of movement on your desk.

DPI is always set on the mouse itself (or via software) and as such translates to the sensitivity of the mouse in Windows, internet browsers, and so on. So in general the DPI of your mouse will determine how sensitive it is throughout your entire system.

It is a common marketing gimmick to advertise gaming mice with absurdly high DPI counts, but most professional gamers set their DPI anywhere between 400 and 1600, making these absurdly high DPI possibilities virtually useless. Aside from that, some sensors will introduce smoothing at higher DPI levels, so it’s always safer to stay at 1600 or lower. If you want a higher overall sensitivity you can always up your ingame sensitivity.

Most mice have a DPI button located below the scroll wheel, allowing you to cycle between different DPI settings.


Sensitivity (or ‘sens’) is the ingame sensitivity setting. Contrary to DPI this only applies in the game where you set it in, so it’s perfectly possible to have multiple different sensitivities across a variety of games installed on the same machine whilst using the same mouse. Different games also use different ways of measuring sensitivity, so ‘1’ sensitivity in game A won’t necessarily mean the same in game B.

Looking at DPI or ingame sensitivity on its own to compare is usually a bad idea. Player A can have his mouse set to 1600 DPI with an ingame sensitivity of 2, whilst player B can have her mouse set to 400 DPI with an ingame sensitivity of 8. These look like wildly different configurations, but in reality both players’ mice will be equally sensitive to movement.


DPI * Sensitivity

Since gamers like to compare settings, gear, and so forth, and comparing raw sensitivity and DPI can get confusing we use eDPI when comparing ‘true sensitivities.’ eDPI stands for effective Dots Per Inch, and it’s calculated by multiplying the mouse DPI with the ingame sensitivity. This gives gamers a way of comparing the true sensitivity of different players, regardless of their hardware or software settings.

Player A has a DPI of 1600, and an ingame sens of 2.
Player B has a DPI of 400, and an ingame sens of 8.

Player A's eDPI = 3200 (1600*2)
Player B's eDPI = 3200 (400*8)

Both players have the same true sensitivity (eDPI), though their DPI and ingame sens are very different.

Is 480 eDpi as fast as 480 dpi


If your in-game sens is 1, yes.


if i were to say had an 800 dpi and 0.65 in game. 520 edpi. If i changed my dpi to 1600 and my ingame sens to 0.325. Would my aim and feeling of sensitivity be the same or would it differ and be completely different from my original sens even tho the edpi is the same.

If you have the answer please respond to this comment

Different DPI levels can feel different so you might definitely have a different feeling when switching like that. That said: it should be rather easy to overcome, and a lot of people won’t even notice the difference.

Just help

Hey i have a question. Well my fotrnite sens is different then from every one just because my sens it shows for example 65,5 and when i look to my friends and youtubers and everyone i see they have dots(.) Instead of commas(,) like me please help


english uk and english us use dots and commas differently, its the same thing.


Well guys, this was for me the best guide to warzone settings ever!!! eDPI now 5000 and still lowering it, i have a different game now, life is much more easy 🙂
Also i did the graphic settings, its perfect nothing more to say.
Good job and i will follow the site if new games are up!!!

Hey, thanks for the kind words! That’s always appreciated. Love to hear that you’re bossing it ingame too!


Hi, just a question cause of warzone, at the moment i use sens of 25 and dpi of 1500, which means my edpi should be 37.500 if i understand you right. so i am much higher then the average.
If i would lower the settings to average, i have the feeling the players is moving and turning much too slow ingame, or said in other way, i need to do a much bigger difference on the mousepad to turn the player around.
I dont get it how pro´s can use those edpi setting and be fast in game – for me this is nearly unplayable with that low edpi.
Any help in this point?

It’s really a question of getting used to it. If you feel comfortable at you current sensitivity and you feel like you’re hitting all of your shots then there’s no real need to switch, but the reason all pros play at a ‘lower’ (at least when compared to what many players who are more casual use) sensitivities is because it allows them to have much more control over their micro movements. That said: aside from getting a mousepad that’s big enough to accommodate a lower sens (you’ll find that all pads that pros use are much larger than what you find on an average office desk, for example) it’s just a matter of getting used to it. After a while it starts to feel more natural.
Some people are fans of gradually lowering your sensitivity, which is something that you can try if you want, but I am personally more partial to the ‘cold turkey’ method where you just lower it in one go. That way you don’t have to get used to a myriad of different sensitivities.

Hope this helps a bit!


thank you, i was just wondering if the formula was correct but you also did the math so i dont have to do it anymore. I was talking about fortnite but what if i lower my y-sens to 3.2 and my x-sens stays at 3.5 with a dpi of 2300, whats my edpi then?


so i play on a mouse with a costumizable software so i have a dpi of 2300 and my in game sens is 3.5 but i want to change mice and want the ninja air58 wich doesnt have a software so i want my dpi to 800 but i want the same eDPI so then i will have to first do 2300*3.5 =8050 and then i will have to do 8050/800 = ? If im wrong pls let me know


i have a Zeus e2 from ibuygaming and the highest normal dpi is 3200 is that high or normal for pc players?


Does this mean i have 75600 eDPI? I have 30 sense in R6 which translates to 36 (1.2*R6 sense for CSGO sense), and if I multiply my CSGO at 36 with my dpi at 2100 I get 75600?


Thank you for sharing such an amazing guide. As a gamer, I would recommend 1k to 1600 for MMO games, and for a shooter game, 400 would be enough. What are your thoughts about it?


Thanks man really appreciated.


Can u help me ? I was using 3.0 in game sens, and now that i’ve changed to 800 dpi, my sens is very low, i have to put 7.0 now.. whats wrong ? i see the pro players here using 0.75 with 800 dpi … HOW ?? it’s impossible to play like that… can u help me ?


Does your monitor resolution affect the DPI a player would use?

For instance, if I play a game at 1440p I might need a higher DPI since to move 100 pixels at 1080p would result in 1 inch of movement on my screen, while, 100px at 1440p might only be only 1/2 an inch on a higher resolution screen. Am I thinking about this correctly?

I ask because most pros are playing at 1080p and I play at 1440p, so if I use the average pro eDPI, I have to move my mouse a literal mile to turn around in-game which doesn’t seem realistic.

For reference, in Valorant, I play at eDPI 516 compared to average 277(I think it’s closer to 330) which is 1.86x(1.56x) higher and 1440/1080 is 1.33x higher which is enough to correlate the difference to me.

Side comment: the infographic posted yesterday on the /r/valorant claims that the average eDPI is 277 but I think the average is skewed low because of how the calculation and statistics are done.


Can you answer me if the chipset driver version of a motherboard can influence the accuracy of a mouse? I tested a few different versions and I feel a little difference in my gameplay .. That much AMD Intel, I tested with several mice


So what’s the best way to find sensitivity in a new shooting game? My friend told me use a ruler to measure the length of moving 360 degrees in the old game then use the same number in the new game.


shadow90810, in that case, dont change the DPI of your mouse, just go in-game settings and change the sensitivity to “0.11”. That will give you 390 eDPI (3550 dpi * 0.11 = 390 eDPI). You will browse the internet like usual and you’ll have pro sensitivity ingame.


I’m confused. I play Warzone with 3550 mouse dpi and 8 in-game sensitivity. The formula posted doesn’t make sense. I’ve tried going down to 500 “like the pros” but it’s literally unusable. I can’t even browse the internet. The cursor moves like 1 inch on screen for every 10 inches on the mouse pad. What am I doing wrong?


How does mouse sensitivity in Windows settings affect the eDPI? There is a scale with range between “1-10”. Does anybody know what multiplier this scale uses? I keep mine in the middle at “5” as I believe it does not affect other settings. Can anybody advise?

If I play cod:mw my normal dpi is 5700 ingame sense is usually 5. From what I’ve read I should turn my dpi down but I like quicker turns. I’m having trouble lowering my dpi and finding a good in game sense. What would might you recommend?

“Different games also use different ways of measuring sensitivity, so ‘1’ sensitivity in game A won’t necessarily mean the same in game B.”

According to your logic, if different games have 1 as default setting and are not the same sensitivity then eDPI would be completely useless
Game A: 1 * 400 dpi = Game B: 1* 400 dpi
If they do not feel the same, how would eDPI work?


help me i use 400DPI in-game sens 2.9 window sens 5 what is my edpi??


But how did you get 0.75 from 5 Windows Windows sensitivity

Krishna Sathya

how about zoom sensitivity? it is count?


How do you find your mouse dpi?


edpi is a strange use, it’s not actually an effective dpi, since in a game we are talking about measurements of angle, not inches on a mouse pad, the math is superficially easy, but it’s not intuitive, like if someone says they use “960” edpi, I can’t quickly see in my head what that means, I much prefer a term like “400 equivalent” or cm/revolution.

If I use 0.6, and a 1600dpi mouse. I can take 1600/400 = 4.0, and then do 4.0*0.6 and I get 2.4@400, note that “edpi” is special case of “1 equivalent” -> 960@1, the reason why I like this is that most people have tried 400dpi, basically every non-gaming mouse is 400dpi, and so we can quickly figure out in our minds what means in real terms, and to people not familiar with “pro settings”, they don’t have to do any heavy lifting they just drop their mouse down to 400dpi and they can feel the sens.

Even better is cm/rev because it’s game agnostic, I can just do `2.54 × 360 / (sense × yaw × dpi)`, where yaw is 0.022 (for counter-strike), and I get 43.3cm/rev, plus this standard has been used since early quake pro days.


i dont understand my eDPI . . . . .i play CSGO and I use 400 DPI and my sensivity in-game is 1.5 so whats my eDPI??? can u guys answer me??

One interesting observation is that if you decide to use motion blur reduction by strobing (e.g. ULMB, ELMB, DyAc), is that without motion blur, mouse microstutters are much more visible.

Blur-reduced modes look much better if you use a accurate ultra-high DPI (1600dpi+) and compensate by lowering in-game sensitivity.

Your Windows desktop will move too fast, but you can configure mouse profiles to automatically raise DPI when your game launches (or steam.exe launches) and lower DPI when your game (or Steam.exe) exits.

You want your mouseturns left/right to be as smooth (stutterless) as keyboard strafe left/right. That can be very hard.

But by carefully raising DPI, it makes ULMB look so much better at all mouse movement speeds (slow mouse movements & flick mouse movements), especially if your framerates are matched with refresh rate. Ultra-high DPI with recent mouse sensor, on a very good mouse (1000Hz or true-2000Hz like Cougar Minos X5), with very clean mouse feet, on a very good mousepad. Makes a huge difference in making ULMB look better, it actually looks like my mouseturns are TestUFO-smooth.

How do I get my edpi to be the same as my desktop dpi?


So what would be 6 x and y sens multiplied by 800 dip
