eDPI Calculator
How to use it: pick your game, type your mouse DPI (or tap 400, 800, 1600 or 3200) and your in-game sensitivity. eDPI updates as you type. For Valorant, CS2, Apex Legends and Overwatch 2 you also get your cm/360 and the matching sensitivity in the other three games.
This eDPI calculator multiplies your mouse DPI by your in-game sensitivity to give your effective DPI, the one number that describes how fast your aim really is. Pick a game, enter both values and the result appears instantly. For four shooters it also shows how far you move the mouse for a full 360 degree turn.
Two players can use very different settings and still aim at exactly the same speed. Someone on 400 DPI with a Valorant sensitivity of 0.8 and someone on 1600 DPI with 0.2 both have an eDPI of 320. The calculator makes that visible, so you can compare your setup with a friend or a pro player, or keep the same feel when you buy a new mouse.
How to use the eDPI calculator
- Choose your game from the row of buttons: Any game, Valorant, CS2, Apex Legends, Overwatch 2, Call of Duty or Fortnite. Picking a game loads a typical starting sensitivity for it (for example 0.4 for Valorant and 1.27 for CS2), which you then replace with your own.
- Enter your Mouse DPI. The field starts at 800, and the quick buttons fill in 400, 800, 1600 or 3200. If you do not know your real DPI, measure it first with the mouse DPI analyzer.
- Enter your In-game sensitivity exactly as the game’s settings menu shows it. Decimals such as 0.35 are fine. For Fortnite the field changes to Mouse Sensitivity X (%): type the percentage, such as 8.
- Read the green number in the first tile. That is your eDPI. Under 100 it shows two decimals, above 100 one decimal.
- For Valorant, CS2, Apex Legends and Overwatch 2, read the cm / 360° and in / 360° tiles, then the Same feel in other games list underneath.
The calculator remembers your last game, DPI and sensitivity in your browser on this device, so they are still there next time. Nothing is sent to a server.
The eDPI formula
eDPI (effective dots per inch) is your mouse DPI multiplied by your in-game sensitivity:
eDPI = DPI x in-game sensitivity
DPI is how many counts the mouse sensor reports for each inch it moves. The game turns each count into a small rotation of the camera, scaled by your sensitivity. Multiply the two and you get one value that stands for your overall speed, so doubling either the DPI or the sensitivity doubles the eDPI. For a longer walk through DPI, sensitivity and why players use eDPI, read eDPI explained.
Fortnite is the exception in this tool. Its menu shows sensitivity as a percentage, so the calculator divides by 100 first: 800 DPI at 8.0% is 800 x 0.08 = 64 eDPI.
| DPI | Valorant sensitivity | eDPI |
|---|---|---|
| 400 | 0.8 | 320 |
| 800 | 0.4 | 320 |
| 1600 | 0.2 | 320 |
| 800 | 0.35 | 280 |
| 800 | 0.3 | 240 |
All three 320 rows turn the camera the same amount for the same hand movement. The calculator shows 40.8 cm for a full turn in each case.
What cm/360 tells you
cm/360 is the distance you slide the mouse to turn a full circle in the game. It is the most direct way to describe sensitivity, because it is a real distance on your desk rather than a number that only makes sense inside one game. A higher cm/360 means slower, more controlled aim; a lower one means faster turns.
The calculator works it out from the game’s yaw, the number of degrees the camera turns for one mouse count at sensitivity 1:
inches per 360 = 360 / (yaw x sensitivity x DPI), then cm = inches x 2.54.
| Game | Yaw (degrees per count) | 800 DPI example |
|---|---|---|
| Valorant | 0.07 | 0.4 gives 40.8 cm |
| CS2 | 0.022 | 1.27 gives 40.9 cm |
| Apex Legends | 0.022 | 1.5 gives 34.6 cm |
| Overwatch 2 | 0.0066 | 4.24 gives 40.8 cm |
These yaw values match the ones listed by the CSDB sensitivity converter, which also gives 34.6 cm for CS2 at 800 DPI and sensitivity 1.5, the same figure this calculator shows. For Apex Legends the result assumes your ADS multipliers are left at 1.0.
Why eDPI only compares players of the same game
eDPI is only fair between players of one game, because every game turns a different amount per mouse count. Valorant’s yaw of 0.07 is about 3.18 times CS2’s 0.022, so 320 eDPI in Valorant feels like roughly 1,016 eDPI in CS2. Both settings give about 40.8 to 40.9 cm per 360.
That is why the calculator gives two kinds of answer. Use eDPI to compare yourself with someone who plays the same game. Use cm/360, or the Same feel in other games list, when you switch between games. The list keeps your DPI and changes only the sensitivity, so a Valorant player on 800 DPI and 0.4 sees CS2 1.273, Apex Legends 1.273 and Overwatch 2 4.242.
For more control over the conversion, such as changing DPI at the same time, use the sensitivity converter.
Games this calculator covers
Every game gets a plain eDPI. The extra outputs depend on whether the game’s rotation is stable enough to calculate.
| Game | eDPI | 360 distance and conversion |
|---|---|---|
| Valorant, CS2, Apex Legends, Overwatch 2 | DPI x sensitivity | Yes |
| Fortnite | DPI x (percentage / 100) | No |
| Call of Duty | DPI x mouse sensitivity | No |
| Any game | DPI x sensitivity | No |
The calculator leaves out a 360 distance for Call of Duty because the sensitivity scale has changed between Call of Duty titles, and a single value would be wrong for some of them. Fortnite and Any game also skip it, so you never see a misleading number.
Each game also has its own page with the same tool already set to that game, plus notes for its settings menu:
- Valorant sensitivity and eDPI
- CS2 sensitivity and eDPI
- Fortnite sensitivity and eDPI
- Apex Legends sensitivity and eDPI
- Overwatch 2 sensitivity and eDPI
- Call of Duty sensitivity and eDPI
What is a good eDPI?
A good eDPI is the one that lets you turn fast enough for your game while still hitting small, precise adjustments. There is no single right number, but the settings pro players publish give a useful reference point.
- CS2: CSDB tracks the settings of 1,007 professional players. Its data page gives a median eDPI of 800 and a mean of 850, with AWPers a little higher (median 840) than riflers (median 800). At 800 eDPI a full turn takes 52.0 cm.
- Valorant: Omni Calculator puts the average Valorant pro eDPI at 280. In this calculator, 280 (for example 800 DPI and 0.35) works out to 46.7 cm per 360.
- Fortnite: Omni Calculator reports that among more than 300 pro players and streamers in 2019, the most common eDPI range was 32 to 82. With 800 DPI that is roughly 4% to 10% in the Fortnite menu.
Pro numbers are a starting point, not a target. Pros often use large mouse pads and aim with the whole arm, which suits a low eDPI. On a small pad, or if you aim mainly with your wrist, a higher eDPI may be more comfortable.
| cm/360 | Valorant eDPI | CS2 eDPI |
|---|---|---|
| 30 cm | 435 | 1,385 |
| 40 cm | 327 | 1,039 |
| 50 cm | 261 | 831 |
| 60 cm | 218 | 693 |
Values in this table are rounded from the formula above. Pick the row that feels close to your current turn distance, then check your exact settings in the calculator.
How to find your own sensitivity
The quickest way to settle on a setting is to start from a turn distance you can actually reach on your mouse pad, then make small changes and give each one time.
- Fix your DPI. Choose one value, such as 800 or 1600, and leave it alone. Change only the in-game sensitivity from now on.
- Check the full turn. Set a sensitivity where one smooth sweep across your pad turns you a full 360 degrees with a little room to spare.
- Play with it for several days. Use it in matches and in short sessions on the aim trainer before deciding anything.
- Adjust in small steps. If it feels too slow or too fast, change the sensitivity by about 10 percent, not by half or double.
- Write down the result. Note your eDPI and cm/360 from this calculator, so you can restore the exact feel after a reinstall or a new mouse.
Aim is not only about settings. How quickly you react to a target matters too, and you can measure that with the reaction time test. If you suspect your mouse itself, the polling rate test checks how often it reports its position.
Things that change your aim but not your eDPI
eDPI is a simple multiplication, so some settings that affect how your aim feels are not part of it.
- Windows pointer speed: most modern shooters read raw mouse input, so the pointer speed slider changes the desktop cursor but not your in-game aim.
- Mouse acceleration: with acceleration on, the same hand movement turns you different amounts depending on speed, so no fixed eDPI or cm/360 describes it. Turn it off if you want these numbers to match what you feel.
- Scoped and ADS sensitivity: the calculator uses your main (hip fire) sensitivity. Scoped multipliers change the speed only while aiming down sights.
- Real versus advertised DPI: a mouse set to 800 DPI can report a little more or less. If your eDPI matches a friend’s but still feels different, measure your actual DPI.
Frequently asked questions
How do I calculate eDPI?
Multiply your mouse DPI by your in-game sensitivity. For example, 800 DPI x 0.4 sensitivity = 320 eDPI. In Fortnite, divide the percentage by 100 first, so 800 DPI at 8% gives 64 eDPI.
Is a lower eDPI better?
Not automatically. A lower eDPI makes small, precise adjustments easier, while a higher eDPI lets you turn faster with less arm movement. Many pros use fairly low values, but the right one depends on your game, your pad size and how you hold the mouse.
Is 800 DPI good for gaming?
Yes. 800 DPI is one of the most common settings, and it is the default in this calculator. Because eDPI multiplies DPI by sensitivity, 800 DPI at 0.4 and 1600 DPI at 0.2 feel the same, so the DPI number on its own matters less than the total.
Can I compare eDPI between Valorant and CS2?
Not directly. Each game turns a different amount per mouse count, so 320 eDPI in Valorant feels like roughly 1,016 eDPI in CS2. Compare cm/360 instead, or read the Same feel in other games list in the calculator.
Does DPI or sensitivity matter more?
Neither. They count equally because eDPI multiplies them, so doubling either one doubles your eDPI. A higher DPI with a lower sensitivity can give slightly finer steps, but the overall speed is the same.
Why is there no 360 distance for Fortnite or Call of Duty?
The 360 distance needs a reliable rotation value for the game. This calculator only shows it for Valorant, CS2, Apex Legends and Overwatch 2. Call of Duty titles use different sensitivity scales, and Fortnite is not converted here, so the tiles show a dash rather than a wrong number.
Is my data saved?
Only on your own device. The calculator stores your last game, DPI and sensitivity in your browser’s local storage so they reload next time. Nothing is uploaded, and clearing your browser data removes them.
