eDPI Calculator
Calculate your effective DPI (eDPI) for any game from mouse DPI and in-game sensitivity. Free online eDPI calculator with equivalent sensitivity chart and detailed breakdown.
About This Calculator
The eDPI Calculator (effective dots per inch) helps gamers find their real mouse sensitivity by combining their mouse DPI and in-game sensitivity into a single comparable value. Whether you play CS:GO, Valorant, Fortnite, Overwatch, Apex Legends, or Call of Duty, knowing your eDPI allows you to compare your settings with friends and professional players, and to maintain consistent sensitivity when adjusting your hardware or game settings.
The formula is simple: eDPI = Mouse DPI × In-Game Sensitivity. For example, if your mouse is set to 800 DPI and your in-game sensitivity is 2.5, your eDPI is 2000. This means you can achieve the same effective sensitivity with different DPI values by adjusting your in-game sensitivity proportionally. The calculator also shows equivalent sensitivity values at common DPI levels (400, 800, 1200, 1600, 2000, 2400, and 3200) so you can find alternative configurations that feel exactly the same.
The game preset selector lets you choose from popular games, but the calculation remains the same across all games. Different games use different sensitivity scales (decimal in CS:GO and Valorant, percentage in Fortnite), and the preset helps you identify the correct format. The eDPI Calculator is free, works on any device, and all your inputs are saved in the URL for easy sharing.
Frequently Asked Questions
What is eDPI?
eDPI stands for effective dots per inch. It is a standardized measure of mouse sensitivity calculated by multiplying your mouse DPI by your in-game sensitivity setting. eDPI = DPI × Sensitivity. This allows gamers to compare their true sensitivity regardless of hardware or software settings.
How is eDPI calculated?
eDPI is calculated by multiplying your mouse DPI (dots per inch) by your in-game mouse sensitivity. For example, if your mouse is set to 800 DPI and your in-game sensitivity is 2.5, your eDPI is 800 × 2.5 = 2000. This value represents your effective sensitivity regardless of the game you are playing.
What is a good eDPI for gaming?
The ideal eDPI varies by game and personal preference. For CS:GO, professional players average around 900 eDPI. For Valorant, pros average about 280 eDPI due to the precision needed. For Fortnite, the common eDPI range for pros is 32 to 82 (using percentage-based sensitivity). For Overwatch, the average pro eDPI is around 4800 due to the fast-paced gameplay. Start with these ranges and adjust to find what feels comfortable.
What is the difference between DPI and eDPI?
DPI (dots per inch) is a hardware setting on your mouse that determines how many pixels the cursor moves per inch of physical mouse movement. eDPI (effective DPI) is DPI multiplied by in-game sensitivity, giving you a combined measure of your total mouse sensitivity. Two players with different DPI and sensitivity settings can have the same eDPI and therefore the same effective sensitivity.
Can you compare eDPI between different games?
No, eDPI cannot be directly compared between different games because each game uses its own sensitivity scale and formula. A sensitivity of 2.5 in one game may not produce the same cm/360 as 2.5 in another. However, eDPI is useful for comparing settings between players in the same game, or for transferring your sensitivity between different profiles in the same game.
What mouse DPI do professional gamers use?
Most professional gamers use a DPI between 400 and 1600, with 400 and 800 being the most common. They prefer to adjust their in-game sensitivity rather than using very high DPI values, as high DPI can introduce issues like sensor smoothing where the mouse tries to predict movement instead of reporting raw input.
How do I convert my sensitivity between games?
To convert sensitivity between different games, you need to measure your cm/360 (the distance your mouse travels on the mouse pad to perform a full 360-degree turn in-game). This is a real-world measurement that transfers across any game. Many online tools can help you convert sensitivity between popular games like CS:GO, Valorant, Overwatch, and Fortnite using cm/360 as the reference.
