EDPI Calculator — Effective Dots Per Inch
Precision Sensitivity Calibration for Pro Gamers
What Is EDPI?
EDPI — Effective Dots Per Inch — is the single number that represents your true, hardware-independent mouse sensitivity. It is calculated by multiplying your mouse DPI by your in-game sensitivity value.
The formula is straightforward: EDPI = DPI × In-Game Sensitivity. For example, a player running 800 DPI at a sensitivity of 2.5 in Valorant has an EDPI of 2,000. Another player using 1,600 DPI at 1.25 sensitivity also lands at 2,000 EDPI. Despite different settings, both players move their crosshair the exact same distance for every inch of mouse movement. EDPI strips away the noise of individual DPI preferences and gives you a universal baseline for comparison.
This concept matters across every major competitive shooter. Whether you're calibrating for CS2, Valorant, Overwatch 2, Apex Legends, or Rainbow Six Siege, EDPI lets you translate sensitivity settings from one game to another, share configs with teammates, and track how your sensitivity evolves over months of practice.
Low DPI, High Sens
400 DPI × 4.0 sensitivity = 1,600 EDPI. Common in legacy CS:GO setups where players preferred granular hardware control.
High DPI, Low Sens
1,600 DPI × 1.0 sensitivity = 1,600 EDPI. Modern pro standard — higher polling rates and smoother tracking with lower in-game values.
Mid-Range Balance
800 DPI × 2.0 sensitivity = 1,600 EDPI. The sweet spot for most players transitioning between multiple titles.
Calculate Your EDPI
Enter your current mouse DPI and in-game sensitivity to find your effective dots per inch. Use the result to compare settings across games or match a pro player's config.

Common EDPI Ranges by Game
Valorant: 70–150 EDPI (most pros sit between 80–120).
CS2: 1,500–3,500 EDPI (legacy 400 DPI setups push higher in-game sens).
Overwatch 2: 30–100 EDPI (tracelens-based; many aim trainers recommend the lower end).
Apex Legends: 30–80 EDPI (hip-fire tracking benefits from lower effective sensitivity).
Rainbow Six Siege: 1,000–2,500 EDPI (tight angles reward conservative settings).
Translate Between Titles
Each game applies its own internal multiplier to raw sensitivity. AimSync uses community-verified conversion factors so you can take your EDPI from one title and find the closest equivalent in another. For instance, a 100 EDPI setup in Valorant roughly translates to 1,800 EDPI in CS2 for comparable 180° flick distance.
Why EDPI Matters
Without EDPI, comparing sensitivity settings is like comparing temperatures in Fahrenheit and Celsius — the numbers look different, but the underlying reality can be identical. EDPI is the common language that every serious aim trainer speaks.
When you watch a pro player stream or read a tournament breakdown, you'll often see their DPI and in-game sensitivity listed separately. That's useful information, but it doesn't immediately tell you whether their setup is aggressive or conservative. EDPI distills those two numbers into one actionable metric. Here's why that matters in practice:
Accurate Config Sharing
Your teammate says they're running 1,600 DPI at 0.8 sens in Valorant. Without EDPI, you can't tell if that's fast or slow. Their EDPI is 1,280 — now you know exactly where it sits relative to your own 800 DPI × 1.5 = 1,200 EDPI. You're nearly matched.
Consistent Crosshair Placement
If you switch between CS2 and Valorant, matching EDPI (adjusted per game's engine) ensures your wrist-flick muscle memory transfers. Players who ignore EDPI waste weeks relearning flick distance every time they hop titles.
Track Sensitivity Progress
Record your EDPI over time. Many players gradually lower their sensitivity as their aim matures — dropping from 1,800 EDPI to 1,200 EDPI over six months of deliberate practice is a common progression path documented across pro ladders.
Aim Trainer Benchmarking
KovaaK's and Aim Lab configs are often tuned to specific EDPI ranges. Running a scenario designed for 1,000 EDPI while you're at 3,000 EDPI means the target sizes and timings don't match competitive conditions. EDPI ensures you train at match-relevant sensitivity.
Hardware Upgrades Without Relearning
Switching from a 400 DPI mouse to a 1,600 DPI mouse? Maintain the same EDPI by adjusting your in-game sensitivity proportionally. Your crosshair behavior stays identical — only the underlying hardware changes.
Community & Coaching Alignment
Coaches, Discord communities, and sensitivity databases all reference EDPI. When you join a ranked scrims group and someone asks "what's your EDPI?", having that number ready shows you understand the fundamentals of sensitivity calibration.
The bottom line: DPI alone tells you nothing about how fast your crosshair moves. In-game sensitivity alone depends on your hardware. EDPI combines both into a single, portable number that works everywhere. Use the calculator above to find yours, then use it as your north star for every sensitivity adjustment going forward.
