What Is a Good eDPI? A Practical Guide for FPS Players

If you play first-person shooters, you’ve probably seen players swap “eDPI” numbers like badges. It’s one of the most useful figures for comparing mouse sensitivity — and one of the most misunderstood. This guide explains what eDPI actually is, how to work yours out, and how to land on a good value without blindly copying someone else’s.

What is eDPI?

eDPI stands for effective DPI. It is a single number that captures how fast your crosshair turns, by combining two settings that are meaningless on their own:

• Mouse DPI — a hardware setting on your mouse: how many counts it reports per inch of movement.
• In-game sensitivity — a multiplier the game applies on top of that.

On their own, neither tells you much. A player on 1600 DPI and 0.2 sensitivity aims exactly like a player on 800 DPI and 0.4 — both have an eDPI of 320. That’s the whole point of eDPI: it’s the value that stays the same when two setups feel the same, which is why players share it instead of raw DPI.

How to calculate eDPI

The formula is just multiplication:

eDPI = mouse DPI × in-game sensitivity

So 800 DPI × 0.4 sensitivity = an eDPI of 320. If you’d rather not do the math, the eDPI calculator does it instantly as you type — and lets you compare your number against the common ranges.

Because it’s a straight multiply, you can raise DPI and lower in-game sens (or the reverse) and keep the same eDPI. The in-game feel is identical. Most players keep DPI somewhere in the 400–1600 range and adjust the in-game value, partly because very high DPI can introduce sensor smoothing on some mice.

What counts as a “good” eDPI?

Here’s the honest answer: there is no single correct eDPI. What’s “good” depends on the game, your space, and your playstyle. A few principles hold up, though:

• Lower eDPI means more centimetres of mouse movement per full turn. That gives you finer control for precise tapping and rifle play, but you need desk space to swing.
• Higher eDPI turns the camera fast from small movements — better for quick flicks and close-range tracking, at the cost of fine precision.
• Tactical shooters (where one tap matters) tend to reward lower eDPI; fast-movement games tend to tolerate higher.

Rather than chase one magic number, pick a value, give it two to four weeks, and only change it deliberately. Constantly switching prevents your aim from building muscle memory, which does more harm than any specific number.

Why CS2 eDPIs look so much higher than Valorant

If you’ve compared the two, you’ll notice CS2 players quote much higher eDPI than Valorant players for what feels like the same aim. That’s not a mistake. CS2 uses a smaller internal yaw value than Valorant, so each mouse count rotates the camera less. To produce the same real-world turn (the same cm/360°), CS2 players need a higher in-game sensitivity — and that pushes the eDPI number up. The physical aim is similar; only the number is different.

This is exactly why eDPI is only comparable within the same game.

eDPI vs cm/360° — which should you actually match?

If you want to carry the same aim feel from one game to another, don’t match eDPI — match cm/360°. That figure measures the physical distance your mouse travels to spin a full 360°, so it’s grounded in real-world distance rather than each game’s internal scaling. The same eDPI in Valorant and CS2 gives different cm/360°, but the same cm/360° feels the same everywhere. You can convert between setups with the cm/360° calculator.

How to find your own good eDPI

A simple, low-drama process:

1. Start from a sane middle ground for your game and try it for a full session.
2. If you’re overshooting flicks and running out of mousepad, your eDPI is probably too high — drop it.
3. If you can’t turn fast enough or your wrist is cramping, it’s probably too low — raise it.
4. Make small changes, one at a time, and commit for a couple of weeks before judging.

Plug your DPI and in-game sensitivity into the eDPI calculator to see where you currently sit, then adjust from there. The best eDPI is the one you stop thinking about — when your hand just goes where your eyes are looking.
