Why It Matters
Why players use an eDPI calculator
eDPI rolls your mouse DPI and in-game sensitivity into one number, making it easier to compare setups, track changes, and understand how fast your aim actually feels. It is a quick benchmarking tool for the same game, especially when you want to compare your settings with friends, pro players, or your own previous setup.

How to use the eDPI calculator
Enter the same values you use in-game and the calculator will instantly show your effective DPI. This works for titles that use standard number-based sensitivity as well as games that display sensitivity as a percentage.
1. Select sensitivity type
Choose number or percentage depending on how your game displays sensitivity.
2. Enter your game sensitivity
Type the value exactly as it appears in the game settings menu.
3. Add your mouse DPI
Use your current DPI and the result updates instantly so you can copy it right away.
What is eDPI?
eDPI stands for effective dots per inch. It combines your mouse DPI and in-game sensitivity into one number so you can describe your aim speed more clearly. The formula is simple: game sensitivity × mouse DPI.
That makes eDPI useful for benchmarking setups inside the same title. A higher eDPI usually means faster overall aim movement, while a lower eDPI generally feels slower and more controlled. What it does not do is create a universal cross-game comparison, because each game scales sensitivity differently.
Why people use it
- Compare your setup with other players in the same game.
- Track sensitivity changes when testing new settings.
- Keep a simple record of your preferred aim speed.
Important reminder
- 500 eDPI in one game does not automatically match 500 eDPI in another.
- Field of view, sensitivity scale, and input behavior still matter.
- Use sensitivity conversion tools when you want true cross-game matching.
Need to check your mouse DPI first?
If you are not sure whether your mouse is actually running at the DPI you expect, test that before relying on eDPI. Measuring your real DPI helps you catch mismatched software profiles, packaging assumptions, or settings you changed and forgot about.
- 1. Place a ruler or measuring tape on your desk or mousepad.
- 2. Pick a reasonable movement distance, because larger distances are usually more accurate.
- 3. Measure how far the mouse moves physically on the surface, not how far the cursor moves on screen.
- 4. Repeat the test a few times and average the result before rounding to a nearby practical DPI value.
If you want to verify that number directly, use the built-in DPI Analyzer page.
Quick Notes
- Raw mouse input matters more than cursor tracking on the display.
- Most common gaming DPI values cluster around clean increments like 400, 800, or 1600.
- Testing several times is usually better than trusting a single run.
Frequently Asked Questions
How is eDPI calculated?
Multiply your in-game sensitivity by your mouse DPI. If a game uses percentage sensitivity, convert that percentage into its decimal form before doing the math.
Can I compare eDPI across different games?
Not reliably. eDPI is most useful inside the same game because each title can use a different sensitivity scale and feel.
What if I do not know my mouse DPI?
Check your mouse software if available, or test it using a DPI analyzer so your eDPI result is based on the real setting you are using.
Do Windows pointer settings break DPI testing?
For proper raw-input based tests, Windows pointer acceleration and pointer speed are generally not the main factor. The more important part is measuring your physical mouse travel correctly.
Why does my result feel different than someone else’s?
eDPI is only one part of how aim feels. FOV, zoom scaling, game-specific sensitivity curves, and input processing can all change the experience.
What if the calculator does not seem right?
Double-check the sensitivity type, your exact in-game value, and your DPI. If the issue continues, try a current browser version and compare the number against a manual calculation.
