What is eDPI? The FPS Sensitivity Metric Explained

If you have ever tried to copy a pro player's aim and ended up flailing wildly, you have run into the eDPI problem. Sensitivity numbers are not portable on their own — a "1.0" in one setup is a "5.0" in another. eDPI fixes that.

The definition

eDPI stands for "effective DPI". It is the result of multiplying your mouse hardware DPI by your in-game sensitivity. The formula is simple:

A player on 800 DPI and 0.5 sensitivity has the same eDPI (400) as a player on 400 DPI and 1.0 sens. They will rotate by the same amount per centimeter of mousepad — which means they have the same aim, even though their raw numbers look different.

Why eDPI exists

In FPS games, mouse movement gets multiplied twice before it becomes turn rotation: once by your hardware DPI (counts per inch reported by the mouse) and once by the game's sensitivity slider (degrees of rotation per count). Either of those numbers can change without affecting the final feel — what matters is the product.

eDPI lets two players with completely different mouse settings compare aim directly. ZywOo runs 400 DPI × 2.0 sens. donk runs 800 DPI × 1.25. Their raw sens values differ by 60%, but ZywOo's eDPI is 800 and donk's is 1000 — only a 25% gap. eDPI tells the truth.

Typical eDPI ranges by game

Different FPS engines use different yaw constants, so eDPI ranges shift between games. A "low" eDPI in Valorant is not the same as a "low" eDPI in CS2 because the engine maths are different. Here is what the pro scene looks like in 2026:

These are not rules — top players exist outside every band. NiKo plays at 560 eDPI in CS2 (well below average). TenZ runs around 248 in Valorant (average duelist). Use ranges as orientation, not prescription.

Common eDPI mistakes

1. Copying eDPI without copying cm/360

eDPI is not portable across games. CS2 eDPI 800 is not the same physical movement as Valorant eDPI 800 — the games' yaw constants differ by ~3.18×. If you switch from CS2 to Valorant and copy your eDPI, you will be aiming 3× too fast. Use cm/360 instead when crossing engines, and let our converter do the math.

2. Chasing pro eDPI

Pros do not all win because of their eDPI. They win because they stuck with one for years and built muscle memory. Picking ZywOo's eDPI and expecting his aim is like buying his shoes and expecting his stride. Find a number you can be consistent with, then keep it.

3. Using eDPI on a calculator instead of a feel test

Two players on identical eDPI can feel completely different if their mousepad surface, grip style, or arm-vs-wrist ratio differs. eDPI is a starting point. Run a 360° test in-game (mark your mouse, do one full rotation, measure the cm) and tune from there.

How to find your eDPI in 30 seconds

1. Open your mouse software (Razer Synapse, Logitech G HUB, etc.) and read your DPI value.
2. Open your game's settings → mouse / aim → read the sensitivity slider.
3. Multiply the two. That is your eDPI.

If your DPI cycles between values via a button on your mouse, make sure you check the active profile — many gaming mice have two or more DPI presets and report whichever is currently selected.

eDPI vs cm/360 — which one matters?

Both. eDPI is the in-game number that is easy to share and compare within a single game. cm/360 (centimeters of mouse travel for a full rotation) is the universal one — it survives across engines and is what your muscle memory actually depends on.

Use eDPI to compare yourself to pros within the same game. Use cm/360 when switching games or comparing across titles. Our pair pages compute both for you on every conversion.

Should you change your eDPI?

Probably not. The single biggest aim improvement most players make is committing to one eDPI for at least a month and training muscle memory at it. Constant tweaking destroys consistency. If you do change it, do so by no more than 10–15% at a time and give it two weeks before judging.

There are good reasons to adjust: your wrist pain disappears at a lower sens, your AWPing flicks consistently overshoot, you got a bigger mousepad. There are bad reasons: a streamer's tweet, a 2-game losing streak, boredom.

eDPI for AWPers vs riflers

AWPers in CS2 typically run lower eDPI (600–900) because precise scope flicks reward smaller mouse movements. Riflers cluster higher (800–1100) for faster spray transfers and clear-house turns. Hybrid players like ZywOo and donk both sit in the 800–1000 band — close enough that they can swap roles without retuning.

In Valorant the spread is tighter — sentinel/initiator pros run 200–280 eDPI, duelists 240–340. Operator users skew slightly lower for their primary weapon's scope precision.
