You just dropped $150 on a premium gaming mouse, but your aim in Valorant still feels off. The problem? You're comparing raw sensitivity settings without accounting for your mouse's DPI. That's where eDPI (effective Dots Per Inch) comes in. Think of it like comparing salaries—you wouldn't compare a $75,000 salary in San Francisco to one in Kansas City without considering cost of living. Similarly, you can't compare in-game sensitivity without factoring in your mouse's DPI. Our eDPI calculator multiplies your mouse DPI by your in-game sensitivity to give you one universal number you can use across games or share with friends.
How to Use
Enter your mouse DPI (check your mouse software—common values are 400, 800, or 1600). Then input your in-game sensitivity multiplier. The calculator instantly shows your eDPI. Compare this number across different games or use it to maintain consistent aim when switching setups.
Pro Tips
Find your comfort zone by testing eDPI ranges between 200-800 for tactical shooters like CS2 or Valorant. Stick with one setting for at least two weeks before judging it. Write down your eDPI somewhere—you'll thank yourself when setting up a new PC or helping a friend. If you play multiple genres, consider having different eDPIs: lower for FPS games, higher for MOBAs or RTS where quick camera movement matters more than precision.
Common Mistakes to Avoid
First, copying pro players' eDPI blindly. Just because TenZ uses a certain eDPI doesn't mean it fits your setup, desk space, or playstyle. Second, changing your eDPI constantly. Muscle memory takes weeks to build—switching every few days destroys any progress. Third, ignoring mousepad size. A $50 large mousepad with low sensitivity beats cramping a high-eDPI setup on a tiny pad. Your physical setup matters just as much as the numbers.
Frequently Asked Questions
What's a good eDPI for competitive FPS games?
Most pros in games like Valorant and CS2 use eDPI between 200-400. For example, 800 DPI with 0.3 sensitivity equals 240 eDPI. Beginners often start higher (600-1000) and gradually lower it as aim improves.
How do I check my mouse DPI?
Most gaming mice ($40-$150 range) have software like Logitech G Hub, Razer Synapse, or SteelSeries GG. Open the software and look for DPI settings. Budget mice without software often default to 800 or 1600 DPI.
Can I use the same eDPI for different games?
Yes, but games scale differently. An eDPI of 320 in Valorant equals roughly 0.88 sensitivity in Overwatch 2 at the same 800 DPI. Use conversion tools for exact matches across titles.
