Why your mouse settings feel impossible to copy
Every gamer has had this experience: a friend or a professional player shares their sensitivity, you type in the same number, and the mouse feels completely different. The confusion has a simple cause. In-game sensitivity is only half the setting; the other half is the mouse's DPI, and the two multiply together into the number that actually determines how fast you turn. That number is called eDPI, and it is the only fair way to compare settings between players, mice, and games. The calculator on this page computes eDPI from DPI and sensitivity, and also converts it into centimetres per 360-degree turn, which is the physical distance your hand travels to spin fully around. Once you think in eDPI and centimetres per 360, settings stop being mysterious and start being portable.
The multiplication is straightforward but its consequences are not obvious. Eight hundred DPI at 1.0 sensitivity and sixteen hundred DPI at 0.5 sensitivity are both eight hundred eDPI, and they feel identical in game, because the game receives the same total counts per inch of hand movement. Doubling DPI while halving sensitivity changes nothing about turning speed, which is why arguing about DPI alone is meaningless. What DPI does change is granularity: higher DPI reports hand movement in finer steps, which can feel smoother on very slow settings, but beyond a point the extra steps exceed what the game and the hand can use. For most players, eight hundred or sixteen hundred DPI is the sweet spot, with sensitivity adjusted to reach the desired eDPI, and chasing extreme DPI values adds nothing once eDPI is matched.
Centimetres per 360: the number your arm understands
eDPI is useful for comparison, but centimetres per 360 is useful for feel, because it describes what your arm actually does. It answers the question: if I want to turn all the way around, how far must my hand travel across the pad? A low value, such as fifteen centimetres, means fast turning with small wrist movements, which suits fast-paced games and small desks but makes precise long-range aiming harder, because tiny hand errors become large aim errors. A high value, such as sixty centimetres, means slow, deliberate turning with full arm movements, which suits precise aiming but demands a large pad and real desk space. Most players settle between twenty-five and fifty centimetres, balancing speed against precision for their game and their space.
Desk space is the hidden constraint on sensitivity, and it is the one most guides understate. A player with a small pad cannot physically use a high centimetres-per-360 setting, because a full turn would run off the pad's edge, forcing constant lifting and repositioning that breaks aim. Conversely, a player with a huge pad who uses a very fast setting wastes the space and the precision it could provide. Before choosing a sensitivity, measure your usable pad width and check that a 180-degree turn, which is half the centimetres-per-360 value, fits comfortably with room to spare. If it does not, either raise sensitivity or buy a bigger pad; the pad is usually the cheaper fix, and it improves comfort regardless of settings.
Finding your sensitivity instead of copying someone else's
Copying a professional's eDPI is a reasonable starting point, but it is not a destination, because professionals differ in game, role, hand size, and desk setup. A sniper holding long angles benefits from slower turning and finer control, while an entry player clearing rooms benefits from faster turning. Your own best setting is found by experiment within a sensible range: start near the middle of your game's typical range, play for several days rather than judging in ten minutes, and adjust in small steps of about ten percent at a time. Judging too quickly is the classic error, because any new sensitivity feels wrong for the first hour while muscle memory recalibrates, and players who switch hourly never let any setting settle.
A useful experiment is the tracking test: in a practice range, track a moving target smoothly at medium distance, then flick to new targets at varying distances. If tracking feels jittery and overshoots constantly, sensitivity is probably too high. If flicks consistently fall short and you run out of pad, sensitivity is probably too low. Adjust until both feel close, then stop adjusting and practice. Muscle memory is built by repetition at a fixed setting, and it is worth more than the perfect number found but never practised. The calculator helps you return to a known setting after experimenting, and to translate a good setting between games that express sensitivity differently, which is where eDPI earns its keep.
| eDPI | cm per 360 (approx.) | Typical feel |
|---|---|---|
| 400 | 90 cm | Very slow, very precise |
| 800 | 45 cm | Balanced, popular range |
| 1600 | 23 cm | Fast, wrist-oriented |
| 2400 | 15 cm | Very fast, less precise |
Polling rate, acceleration, and the rest of the setup
Sensitivity is the headline, but three supporting settings affect how it feels. Polling rate, how often the mouse reports its position, is worth setting to one thousand hertz on a modern mouse, because lower rates add latency and make movement feel less smooth, though the difference is subtle compared with sensitivity itself. Mouse acceleration, which makes the same hand movement turn further when moved faster, should almost always be disabled for competitive play, because it breaks the fixed relationship between hand and aim that muscle memory depends on. Windows pointer settings, including enhanced pointer precision, should also be left alone or disabled in game, because a game that reads raw input bypasses them, while a game that does not will behave inconsistently if they change.
Hardware matters less than settings folklore suggests, but it is not irrelevant. A mouse that fits your hand and grip style, palm, claw, or fingertip, reduces fatigue and improves control more than any DPI specification. Weight matters too: lighter mice are easier to move precisely for long sessions, though some players prefer a little weight for stability. Skates and pad surface affect glide, and a worn pad or dirty skates make even a perfect sensitivity feel inconsistent. Fix the cheap things first: clean skates, a flat pad of adequate size, acceleration off, and a sensitivity chosen by experiment. Then, and only then, consider whether a new mouse would actually help, rather than merely feeling like progress.
- Compare settings by eDPI, not by sensitivity or DPI alone.
- Check that a 180-degree turn fits your pad with room to spare.
- Change sensitivity in small steps and judge after days, not minutes.
- Disable mouse acceleration for consistent muscle memory.
- Use 1000 Hz polling and raw input where the game offers it.
Enter your DPI and sensitivity above, note your eDPI and centimetres per 360, and you have a setting you can reproduce, compare, and carry between games. That portability is the real prize: a setting that belongs to you, measured in numbers that mean the same thing everywhere.
Translating sensitivity between games
Different games express sensitivity on different scales, which is why eDPI alone does not always transfer perfectly between titles. Most modern shooters share a similar yaw model, so matching centimetres per 360 across games gives a consistent feel even when the sensitivity numbers look nothing alike. The practical method is to measure your current centimetres per 360 with the calculator, then in the new game adjust sensitivity until a measured mouse movement produces the same turn, using a ruler on the pad and a fixed in-game reference such as a full spin. Online sensitivity converters automate the arithmetic for popular games, but the ruler test remains the ground truth, because converters assume default field-of-view and yaw values that some games change. Once translated, practise in the new game for a few sessions before judging, since even a perfectly matched sensitivity feels unfamiliar in a new engine, new movement system, and new visual style.
