How it works
Mouse DPI (Dots Per Inch) and in-game sensitivity are two separate multipliers that together determine how fast your crosshair moves on screen. Changing DPI while adjusting sensitivity to compensate produces the same in-game movement — but different pixel-level precision characteristics. The Mouse DPI to Sensitivity Converter calculates equivalent sensitivities across different DPI settings and games.
**DPI vs. sensitivity** DPI is a hardware setting (how many pixels the cursor moves per physical inch of mouse movement). Sensitivity is a software multiplier within the game. Effective sensitivity = DPI × in-game sensitivity multiplier. If you play at 800 DPI, 2.5 sensitivity and want to switch to 400 DPI: new sensitivity = 2.5 × (800/400) = 5.0. The crosshair moves identically on screen.
**eDPI (Effective DPI)** eDPI = DPI × in-game sensitivity. This single number describes your actual sensitivity regardless of how you split the multiplier between hardware and software. Professional CS2 players typically use 400–800 DPI with eDPI of 800–1200. Valorant pros: eDPI typically 200–400. Lower eDPI = lower sensitivity = more precise aiming but larger desk sweeps for 180° turns.
**Why many pros use 400 or 800 DPI** Lower DPI reduces input smoothing and acceleration artifacts from the sensor — most gaming mice are tested and tuned for accuracy at these DPI levels. Very high DPI (3200+) can introduce tracking inaccuracies. For the same eDPI, 400 DPI × 10 sensitivity and 800 DPI × 5 sensitivity should feel identical, but many players report that 400–800 DPI feels "cleaner" due to sensor characteristics.
**cm/360 (centimetres per 360-degree turn)** cm/360 = 360 / (eDPI × 0.0254 × game_sensitivity_unit). This expresses sensitivity as physical desk space needed for a full rotation — independent of monitor resolution and DPI. Pros: typically 30–60 cm/360 for FPS (lower = slower, more precise).

Frequently Asked Questions
- The majority of professional FPS players (CS2, Valorant, Apex) use 400 or 800 DPI hardware settings. Logitech's 2024 pro player statistics show approximately 60% at 400 DPI, 30% at 800 DPI, with a small minority at 1600+. The preference for low DPI is partly practical (most sensors perform most accurately at these levels) and partly conventional (low eDPI traditions in the esports scene). The key metric is eDPI, not raw DPI — a pro at 400 DPI × 2.0 sensitivity has the same in-game movement as one at 800 DPI × 1.0.
- Not directly. Higher DPI means the cursor moves more pixels per physical inch — essentially a higher sensitivity. Whether this helps or hurts depends on your preferred eDPI. Very high DPI (3200+) can introduce tracking inaccuracies in some sensors ('pixelskipping' and inconsistent sub-count behaviour). For aiming, the optimal eDPI range for most competitive players is 400–1600 eDPI — low enough to allow precise micro-adjustments, high enough to allow full-arm swings for large flicks. Your physical mouse pad size constrains minimum practical eDPI: a smaller pad requires higher eDPI.
- Mouse acceleration increases cursor speed based on how fast you physically move the mouse — fast movement maps to disproportionately more cursor movement than slow movement. This makes movements inconsistent: the same physical muscle memory produces different cursor displacements depending on speed. For gaming (especially FPS), mouse acceleration is universally recommended to be disabled — you want 1:1 linear mapping between physical movement and cursor movement. Disable in Windows: Settings → Bluetooth & devices → Mouse → Additional mouse settings → Pointer Options → uncheck 'Enhance pointer precision'.
- Use cm/360 as the universal sensitivity unit. Calculate cm/360 for your current game: cm/360 = 360 / (eDPI × game_yaw_constant). Common yaw constants: CS2 = 0.022, Valorant = 0.07 (converted to degrees), Apex Legends ≈ 0.022 (ADS varies). To set matching sensitivity in a new game: new_sens = 360 / (DPI × new_game_yaw × cm/360). This converter handles all game-specific constants automatically — paste your current setup and target game, and it outputs the equivalent sensitivity.
