“Is DPI the same thing as sensitivity?” It’s one of the most common points of confusion for new PC gamers, and honestly, it’s an easy mix-up to make. Both settings affect how fast your cursor or crosshair moves, both get adjusted when you’re trying to dial in your aim, and both show up in the same conversations about “finding your ideal sensitivity.” But they are not the same thing, they live in different places, and understanding the difference will save you a lot of confusion the next time you’re trying to match a pro player’s settings or carry your aim feel between games.
This guide breaks down exactly what each setting controls, how they interact, and how to think about adjusting them correctly.
The Short Version
- DPI (Dots Per Inch) is a hardware setting stored on your mouse itself. It determines how many “counts” the mouse reports to your computer per inch of physical movement.
- Sensitivity is a software setting, usually found inside a specific game or your operating system. It determines how far the cursor or in-game crosshair moves for each count the mouse reports.
DPI is set once on the mouse (or occasionally per DPI-stage button). Sensitivity is set per application — meaning your sensitivity slider in Valorant is separate from the one in CS2, which is separate from your Windows pointer speed.
What DPI Actually Controls
DPI stands for Dots Per Inch, though in the context of mice it’s sometimes more accurately called CPI (Counts Per Inch) — the two terms are used almost interchangeably in gaming, even though technically DPI refers to a printer’s resolution measurement and CPI is the more precise term for mouse sensor output. Regardless of terminology, what it measures is the same: how many discrete position updates (“counts”) your mouse sensor reports to your computer for every inch it physically travels across your mousepad.
A mouse set to 800 DPI reports 800 counts per inch of movement. A mouse set to 1600 DPI reports 1600 counts for that same inch, twice as many position updates for the same physical distance. This is a hardware-level setting, configured either through onboard DPI buttons, manufacturer software, or occasionally hard-coded into cheaper mice with no adjustment at all.
Because DPI is hardware-level, it affects your cursor movement everywhere on your computer, not just inside one game. If you set your mouse to a very high DPI, your desktop cursor will fly across the screen just as fast as your in-game crosshair does.
What Sensitivity Actually Controls
Sensitivity, by contrast, is a software-level multiplier applied on top of whatever counts your mouse is already sending. It lives inside a specific application, be that a game’s settings menu or your operating system’s own pointer speed setting, and it scales how far the cursor or crosshair moves in response to each count.
This is the key distinction: sensitivity doesn’t change anything about your mouse hardware. It changes how the software interprets and reacts to the data the mouse is already sending. That’s why sensitivity settings are per-application: Valorant’s sensitivity slider only affects Valorant, CS2’s only affects CS2, and your Windows pointer speed only affects your desktop and any application that doesn’t override it with its own setting.
This is also why the exact same DPI can feel completely different across two games, if their sensitivity scales aren’t equivalent, or across two players, if one has their sensitivity slider set much higher than the other.
How They Work Together
Here’s where it clicks: your actual, felt aim speed is the product of both settings combined, not either one alone. This combined value has a name: eDPI, or effective DPI.
Mouse DPI × In-Game Sensitivity = eDPI
For example:
- 800 DPI × 0.4 sensitivity = 320 eDPI
- 400 DPI × 0.8 sensitivity = 320 eDPI
Both of these setups produce the exact same on-screen aim speed, despite using completely different DPI numbers. This is the single most important thing to understand about the DPI-vs-sensitivity relationship: neither number means anything on its own. A “high DPI” player and a “low DPI” player can have identical aim feel if their sensitivity multipliers are adjusted to compensate.

Why This Distinction Actually Matters
1. Copying Pro Settings Correctly
If you’ve ever seen a pro player’s settings listed as “DPI: 800,” that number is meaningless without also knowing their in-game sensitivity. Copying only the DPI half of a pro’s settings, without their matching sensitivity, will almost certainly give you a completely different (and likely far too fast) aim feel. Always look for both numbers, or better yet, the combined eDPI.
2. Carrying Your Feel Between Games
Because sensitivity is set per-application, your Valorant sensitivity of “0.4” is not equivalent to a CS2 sensitivity of “0.4” — each game uses its own internal scale. If you want your exact aim feel to transfer cleanly from one game to another, you need to convert your sensitivity using each game’s scale, keeping your eDPI (or cm/360) consistent. Our Mouse Sensitivity Converter does this conversion automatically across 50+ games, so you don’t have to do the math by hand.
3. Diagnosing “My Aim Feels Off” Problems
If your aim feels inconsistent or “off,” it helps to know whether the issue is likely hardware (DPI) or software (sensitivity) related. If your mouse’s actual DPI output doesn’t match what it’s set to — which does happen, especially on budget mice — that’s a hardware-side inconsistency no amount of sensitivity tweaking will fully fix. You can check this directly with our free DPI Analyzer, which measures your mouse’s real DPI output rather than trusting the number printed on the box.
4. Understanding Windows Pointer Speed vs. In-Game Sensitivity
Windows pointer speed is its own separate sensitivity setting, layered on top of your DPI, that affects your desktop cursor and any application that doesn’t explicitly override it. Most competitive games override this with their own in-game sensitivity setting and apply “raw input,” bypassing Windows pointer speed entirely during gameplay. But if a game doesn’t support raw input, or if your Windows pointer speed isn’t set to the recommended default (6/11 notches, no acceleration), it can introduce inconsistency between how your desktop and your game feel.
Should You Adjust DPI or Sensitivity?
For most players, the simplest and most maintainable approach is:
- Pick a comfortable DPI and leave it there. Somewhere in the 400–800 range is a common, well-supported starting point for competitive FPS gaming.
- Adjust in-game sensitivity to fine-tune your feel, since sensitivity sliders typically offer much finer increments than DPI steps, and adjusting them doesn’t affect your desktop cursor speed.
- Only revisit DPI if you’re changing mousepads, monitors, or resolutions in a way that meaningfully changes how much physical space you have to work with.
Keeping DPI fixed and doing your fine-tuning through sensitivity keeps your setup simple and your muscle memory stable, since you’re only ever adjusting one variable at a time.
A Quick Analogy
Think of DPI as the gear ratio on a bicycle, and sensitivity as how hard you’re pedaling. The gear ratio (DPI) determines how much distance one full pedal rotation covers. How hard you pedal (sensitivity) determines your actual speed on top of that. Two riders in different gears, pedaling at different efforts, can end up going exactly the same speed, just like two players with different DPI and sensitivity numbers can end up with identical aim feel.
Common Mistakes to Avoid
- Treating DPI and sensitivity as interchangeable terms. They’re related, but they’re not the same setting, and conflating them leads to confusion when comparing setups.
- Copying a pro’s DPI without their sensitivity (or vice versa). Always look at both, or better, the combined eDPI.
- Constantly changing DPI to adjust speed. Sensitivity sliders are the more precise, more appropriate tool for fine-tuning once your DPI is set.
- Ignoring Windows pointer speed. If a game doesn’t use raw input, your Windows-level pointer settings can quietly affect your in-game feel too.
- Never verifying your mouse’s actual DPI output. Advertised and actual DPI can differ, especially on budget hardware. A quick check with a DPI Analyzer rules this out.
Final Thoughts
DPI and sensitivity are two different settings working together, not two names for the same thing. DPI is a hardware-level count-per-inch value set on the mouse; sensitivity is a software-level multiplier set inside each application. Neither number tells you much in isolation, it’s their combination, your eDPI, that determines how your aim actually feels.
Once you understand the difference, dialing in your setup becomes much simpler: pick a solid DPI and leave it alone, fine-tune through sensitivity, and use eDPI as your reference point whenever you’re comparing settings or switching games.
