Find Your Optimal DPI (Aim Test)

This tool helps you discover a DPI that feels stable and accurate for your aim. The idea is simple: you test a few DPI values, keep your in-game sensitivity the same, and compare your results.

How to use it:

Pick a testing DPI (start with 400 / 800 / 1200 / 1600).
Click Start Test and follow the moving target with your cursor.
Try to keep your cursor on the target as consistently as possible.
Repeat the test for the next DPI value and compare your accuracy + score.

Your best-performing DPI is usually the one that gives you the most control without over-flicking or feeling “too slow.” For best results, keep the same mousepad space, posture, and in-game sensitivity while testing.

Find Your Optimal DPI (Aim Test)

Pick a DPI, play the test, record your score, then try another DPI. Your best score = your best DPI.

Testing DPI:

Testing DPI: 800 | Phase: Idle

Click + Track the Target

How it works: keep your cursor on the target to raise Tracking Accuracy. Click while on the target to count a Hit. Clicking off-target counts a Miss.

Tip: test 400, 800, 1200, 1600 DPI. Keep your in-game sens constant while testing.

eDPI Calculator

Every FPS player uses a combination of hardware DPI and in-game sensitivity.

eDPI combines these two values into a single number:

eDPI = DPI × Sensitivity

This number tells you exactly how fast your crosshair moves and allows you to:

Compare your sensitivity to pro players
Keep consistent aim across different games
Understand whether you’re a low, medium, or high sensitivity player

Use the calculator to instantly find your eDPI.

eDPI Calculator

eDPI helps you compare aim speed across setups. Enter your mouse DPI and in-game sensitivity to calculate your true aiming speed.

Sensitivity Converter

Every FPS game calculates sensitivity differently, so using the same number in multiple games rarely feels consistent.

This Sensitivity Converter automatically adjusts your sens using real in-game scaling values so your aim stays the same when switching between games.

How to Use It:

Select the game you are currently playing.
Select the game you want to switch to.
Enter your current sensitivity value.
Press Convert Sensitivity and the tool will generate your exact matching sensitivity.

This helps you maintain muscle memory when switching games, warming up in aim trainers, or moving from one competitive title to another.

Sensitivity Converter

Convert your sensitivity between games while keeping the same overall mouse feel. Select a “From” game and a “To” game, then enter your current sensitivity.

Tip: this is a conversion tool, not a “perfect aim” guarantee — always fine-tune in-game.
