Aim Lab to Left 4 Dead 2 sensitivity converter
Convert your Aim Lab sensitivity to Left 4 Dead 2 instantly. Same hand motion, perfect muscle memory across both games.
Why Aim Lab sens doesn't match Left 4 Dead 2
At 0.4 sens on 800 DPI, Aim Lab sweeps 40.82 cm across a full 360°. To reproduce that exact arm motion in Left 4 Dead 2, you need sens 1.2727 — about 3.18× your Aim Lab number. Nothing changed except Left 4 Dead 2's yaw of 0.022 vs Aim Lab's 0.07; the centimeters of mouse travel stay the same.

How to apply the converted sensitivity in Left 4 Dead 2
Open Left 4 Dead 2's settings, paste the converted sensitivity into the sens field and keep your 800 DPI if that matches how you play Aim Lab. Run a 360° check on a practice map: the mouse sweep should cover roughly 40.82 cm on your pad — the same distance as in Aim Lab. Only start tuning if the sweep feels off, never before the 360° check.
Common mistakes when converting Aim Lab to Left 4 Dead 2
- Copying the sens without matching DPI
A converted Aim Lab-to-Left 4 Dead 2 number is tied to the DPI you used during conversion. If your Left 4 Dead 2 mouse profile runs a different DPI, the math no longer holds — use Sens Converter's 'different DPI' toggle instead of eyeballing.
- Trusting eDPI across engines
Matching eDPI between Aim Lab and Left 4 Dead 2 does not give matching turn speed, because their yaws are 0.07 and 0.022. Always compare cm/360° (or in/360°), not eDPI, when swapping games.
- Ignoring scoped and ADS overrides
Aim Lab and Left 4 Dead 2 each apply their own scoped / ADS multiplier on top of the base sensitivity. Converting the base is step one — confirm the per-zoom multiplier in Left 4 Dead 2 separately, otherwise scoped aim will feel wrong even with a perfect hipfire match.
Aim Lab → Left 4 Dead 2 FAQ
Why is my converted Left 4 Dead 2 sens different from my Aim Lab number?+
Left 4 Dead 2 has a yaw of 0.022 compared to Aim Lab's 0.07. Their ratio is about 3.18×, so Sens Converter multiplies your Aim Lab sens by that factor to keep cm/360° identical. The raw number looks different, but the arm motion is the same.
Should I keep the same DPI in Aim Lab and Left 4 Dead 2?+
Yes, when possible. Keeping DPI identical means only the in-game multiplier changes, which is the cleanest switch. If you run different DPI in Left 4 Dead 2, enable 'different DPI' in the converter and it absorbs the extra math.
How many decimals should I use in Left 4 Dead 2?+
Left 4 Dead 2 accepts at least 3 decimals; 4-6 is common. Sens Converter outputs enough precision that rounding to 3 decimals keeps the 360° error below one millimetre on a typical 800 DPI setup.
Does FOV affect Aim Lab to Left 4 Dead 2 conversion?+
For the base sensitivity, no — sens is independent of FOV in both engines. If you use a 0% MonitorDistance or similar scaling mode in either game, convert at the FOV you actually run in-game.
