Sensitivity finder
Seven rounds of lower or higher. Each answer halves the range, and you finish with a sensitivity you picked yourself.
How it works
- Pick your game and DPIKeep the range of cm/360 as it is, or narrow it if you already know roughly what you like.
- Set the sensitivity it showsType the number into the game. The tool starts in the middle of your range, measured in turn distance.
- Test it for a minuteUse an aim trainer or the practice range. Track a moving target and flick to a still one.
- Answer lower or higherLower if you want it slower, higher if you want it faster. The range halves.
- Repeat for seven roundsThe last number is your sensitivity. Keep it for at least a week.
Tips for a fair test
Use the same mouse, pad and grip for all seven rounds, and keep the DPI fixed. Test at a similar time of day and when you are warmed up, not on your first game. If two numbers in a row feel the same, pick the lower one and move on.
The search is done in cm/360, so every step is a real change in how far your arm moves, whichever game you play. You can see how your result compares with pros on the cm/360 guide, and convert it to another game with the converter.
Questions
What is the PSA method?
PSA is a way to find a sensitivity by testing and answering one question over and over: would you like it lower or higher? Each answer halves the range, so after seven rounds you are within about one percent of a value that suits you. The name is usually written Perfect Sensitivity Approach or Approximation. This page follows the common seven-round lower or higher process.
Is this the official PSA calculator?
No. It is our own version of the same idea, and it does not store or send anything. The steps are the ones players describe for the method, and the maths is a simple halving of the cm/360 range.
What range of cm/360 should I start with?
The default 15 to 90 cm covers most players. Pros in the games on this site have median turn distances between about 31 and 61 cm. If you already know you want it faster or slower than that, narrow the range before you start.
How long should I test each round?
About a minute in an aim trainer or the practice range is enough. Track a moving target and flick to a still one. Do not change your mouse pad, DPI or grip between rounds.
What if the final sensitivity feels wrong?
Run it again with a narrower range around the result, or give it a few more days. Muscle memory needs time, and a value that feels odd on day one often settles.
Does the result depend on my DPI?
The turn distance does not. If you change your DPI later, use the DPI converter to keep the same aim.
