What is eDPI and Why Do Pros Use It?
eDPI (Effective DPI) is the single number that fully describes a player's sensitivity, regardless of their hardware. The formula is brutally simple: eDPI = Mouse DPI × In-Game Sensitivity. A player using 400 DPI at 2.0 sensitivity and another using 800 DPI at 1.0 sensitivity both have an eDPI of 800 — their mouse will move at exactly the same speed on screen.
Before eDPI became the standard language of competitive gaming, comparing setups was a mess. One CS2 player might say "I use 2.0" and a Valorant player might say "I use 0.35" — both numbers are meaningless without knowing the DPI. eDPI collapses two variables into one, letting coaches, analysts, and players benchmark each other instantly.
The metric is also the foundation for cross-game sensitivity conversion. Because different games use different internal scales, the only reliable way to move a setting from CS2 to Valorant is to first find the physical mouse movement (cm/360°) each produces, then reverse-engineer the sensitivity the target game needs to match it.
The cm/360° Standard: Why Physical Distance Matters More Than Numbers
The Physics Formula
cm per 360°
(360 × 2.54)
DPI × Sens × k
k = game-specific multiplier (e.g. 0.022 for CS2)
Example: 800 DPI, CS2 1.0
51.9 cm
You need 51.9 cm of desk space for one full rotation
The constant 2.54 converts inches to centimetres. The game multiplier k encodes how many degrees of view rotation the game applies per mouse count per sensitivity unit — a value confirmed through direct testing by the mouse-sensitivity.com community.
cm/360° is the gold standard because it describes a physical, measurable reality: the distance your mouse must travel across your pad to complete a 360° rotation. This number is completely independent of game, DPI setting, or software — and it is the common language professionals use when switching between titles or adjusting for a new tournament mousepad.
Your Field of View setting also affects your effective sensitivity in games that scale sensitivity with FOV. Always check your FOV is consistent before comparing cm/360° values with other players.

Valorant sensitivities appear low because the game's internal scale is ~3.18× faster than CS2 at the same number.
The 5 Sensitivity Zones Explained
These zones are based on cm/360° and represent community-consensus ranges observed across thousands of professional and ranked player setups. No zone is inherently "better" — the right choice depends on your role, playstyle, and the games you play.
Extreme Flick — < 15 cm
Rare outside specialist playstyles. Very fast tracking but almost no wrist stability for precise counter-strafing. Common in games with auto-aim assist or large hitboxes. Requires significant muscle-memory adaptation.
Fast — 15–25 cm
Popular with controller-converted PC players and those who favour aggressive angle pushes. Reaction time ceiling is high but crosshair placement consistency suffers at range. Common in fast-TTK titles.
Pro Range — 25–40 cm ✦ Recommended
The sweet spot used by the majority of top-ranked players across CS2, Valorant, and Apex. Balances fast flick speed with enough arm movement for precise micro-adjustments. s1mple (33.6 cm), ScreaM (29.7 cm), ImperialHal (32.5 cm), and TenZ (40.0 cm) all sit here.
Precise — 40–60 cm
Favoured by riflers and support players who prioritise crosshair placement over raw flick speed. Demands a larger mousepad (400 mm minimum width). ZywOo (51.9 cm), device (57.7 cm), and Derke (57.5 cm) operate in this range.
Ultra Low — > 60 cm
Very deliberate, arm-dominant play. Common among AWPers and players who prioritise pinpoint accuracy over multi-kill speed. Requires an extended mousepad of 500 mm+ width. yay (74.2 cm) and jawgemo (60.5 cm) are notable examples.
Why Do Most Pros Use 400 DPI?
A persistent myth in gaming communities is that higher DPI always means better tracking. In practice, the physical movement of your mouse is entirely determined by the cm/360° value — not the DPI in isolation. So why do roughly 70% of pro CS2 players use 400 DPI?
The 3 Real Reasons Pros Choose Low DPI
1. Smoother Sub-Pixel Interpolation
At 400 DPI, each raw input is a larger step — the sensor reports fewer counts per inch. This reduces jitter and micro-stutters visible at high speeds on optical sensors.
2. Larger In-Game Sensitivity Range
Using 400 DPI forces a higher in-game sensitivity number (e.g. 2.0 instead of 1.0), which gives more decimal precision when fine-tuning. A change of 0.1 at 400 DPI is a smaller jump than at 800 DPI.
3. Legacy & Muscle Memory
The 400/800 DPI standard emerged from the Counter-Strike 1.6 era and has been passed down through coaching trees. Familiarity and consistency across boot camps reduces adaptation overhead.

Frequently Asked Questions
Is a higher eDPI better for FPS games?
No. eDPI is neutral — it describes speed, not quality. Higher eDPI means faster sensitivity; lower eDPI means slower. What matters is whether your cm/360° sits in a range your muscle memory can reliably exploit. The best eDPI is the one you can consistently hit your targets with, then fine-tune from there. Use our Reaction Rank calculator to check if your sensitivity is limiting your mechanical ceiling.
How do I convert my CS2 sensitivity to Valorant?
Divide your CS2 sensitivity by the ratio of the two games' multipliers: Valorant sens = CS2 sens × (0.022 / 0.07) ≈ CS2 sens × 0.3143. Our Sensitivity Converter does this automatically while preserving your exact cm/360° across all supported games.
What eDPI should I start with as a beginner?
For CS2, start with 800 DPI × 1.5–2.0 sensitivity (eDPI 1,200–1,600) and lower it gradually over weeks as your crosshair placement improves. For Valorant, 800 DPI × 0.35–0.45 is the most popular beginner bracket. A good rule of thumb: if you frequently overshoot targets, lower your eDPI; if you struggle to track fast enemies, raise it slightly.
Does eDPI matter for ADS (Aim Down Sights) sensitivity?
Your hipfire eDPI and your ADS sensitivity are separate values. Most tactical shooters apply a multiplier to your base sensitivity when you scope in, which changes the effective cm/360°. Use our ADS Ratio Matcher to synchronise your scope sensitivity with your hipfire feel. This is especially critical in Warzone and Apex Legends where split-second ADS is a survival skill.
Why does my peeker's advantage feel different at different sensitivities?
Lower sensitivity means more physical movement is required to track a target that appears suddenly from behind cover — which directly affects how quickly you can react to a peek. Read our Peeker's Advantage Calculator to quantify the milliseconds at stake in your ranked duels.
Does my monitor's resolution affect my ideal eDPI?
Yes — but indirectly. At 4K you are rendering four times the pixels of 1080p, which can reduce your average FPS. Lower FPS creates visible stutter that makes it harder to track at high eDPI. If you play on a high-resolution monitor, check our DLSS Quality Calculator to recover performance without sacrificing clarity.
How do I know if my shots-to-kill breakpoint is affected by my reaction speed?
Weapon TTK (Time to Kill) and your reaction time interact directly. If your reaction time is slower than a weapon's TTK window, you may not complete the kill before the opponent kills you first. Check HTK Breakpoint for damage-per-shot math across armour values.
