Arma 3 eDPI calculator
Use our eDPI calculator for Arma 3 to optimize your gameplay settings and improve performance.
eDPI (effective DPI) = Mouse DPI × In-game Sensitivity. It lets you compare sensitivities across any DPI setting.
Your eDPI
400
800 DPI × 0.5 sens
Pro tip: Most pro players sit between 200–400 eDPI for tactical shooters.
What is a Arma 3 eDPI calculator?
eDPI (effective DPI) is the standard way to compare mouse sensitivity across different setups. It multiplies your hardware DPI by your in-game sensitivity to produce a single number that represents how fast your crosshair moves across the screen — regardless of which mouse you use.
How to use this tool
Enter your mouse DPI (check your driver software or the manufacturer spec sheet) and your Arma 3 in-game sensitivity. Your eDPI is the product of both. A higher eDPI means faster crosshair movement; lower means more precision per physical centimetre moved.
Arma 3 Competitive eDPI Range
150–400
For Milsim FPS titles like Arma 3, competitive players typically use 150–400 eDPI. Milsim titles are slow and tactical — low eDPI gives you the precision they demand. If you're outside this range and struggling with consistency, experimenting within it is a good starting point.
Frequently Asked Questions
What is a good eDPI for Arma 3?
For Arma 3, competitive players commonly use 150–400 eDPI. That said, the best eDPI is one you can control consistently — start in the middle of this range and adjust based on your accuracy in practice.
How do I lower my eDPI without changing my mouse?
Reduce your Arma 3 in-game sensitivity setting. For example, if you're running 800 DPI at 0.5 sensitivity (400 eDPI), dropping to 0.3 sensitivity gives you 240 eDPI. Your hardware DPI stays the same.
Is eDPI better than just using in-game sensitivity?
Yes. In-game sensitivity numbers mean different things in different games — 1.0 in Valorant is very different from 1.0 in Apex Legends. eDPI is universal, making it the only fair way to compare settings across titles or players.
