Place Ruler
Place a physical ruler horizontally on your mousepad, ensuring enough space for horizontal movement.
Set Start
Align with 0 mark, click screen to start. Keep mouse horizontal, do not deviate up/down.

Deep Dive into DPI
DPI (Dots Per Inch) is the core metric of mouse sensor sensitivity, determining how many pixels the cursor moves on screen when the mouse moves one inch physically.
Standard (400-800)
Preferred by FPS pros. Low DPI combined with large arm movements provides ultimate aiming stability.
Golden Range (800-1600)
Balances desktop use and gaming precision. Suitable for MOBA, RTS and most 1080P/2K screen users.
High Precision (3200+)
Designed for 4K/8K ultra-high res screens or multi-monitor workflows. Crossed the entire desktop with just wrist movements.
How it Works
DPI is not magic, but the result of precision optical imaging and digital signal processing.
CMOS Imaging
The sensor captures surface texture at high speed (thousands of frames per second) and compares frame differences to calculate coordinates. Higher DPI means higher parsing density.
Resolution Matching
DPI relates to screen resolution. 800 DPI is comfortable on 1080P, but on 4K screens, the cursor will feel very slow due to increased pixel density.
Use Cases
FPS Gaming
Extreme low DPI + large mousepad for pixel-perfect muscle memory aiming.
Digital Art
Switch DPI based on detail needs. High for macro layout, low for micro adjustments.
Productivity
High DPI with gestures to zip between multiple windows and monitors.
Hardware Check
Verify if new mouse specs are accurate or if there are sensor flaws like acceleration or skipping.
FAQ
Q.Difference between DPI and Sensitivity?
DPI is a hardware parameter (reporting density); Sensitivity is a software multiplier. The product of both determines cursor speed. Suggestion: Adjust DPI first, keep software sensitivity at 1.0 (Windows 6/11) for raw precision.
Q.Why results differ from rated?
Errors within ±5%~10% are normal. Factors include: sensor height, lens tolerance, mousepad reflection, and manual measurement error.
Must Disable 'Mouse Acceleration'
Must Disable 'Mouse Acceleration'
Windows enables 'Enhance Pointer Precision' by default, which is a non-linear acceleration. It causes cursor distance to depend on speed, making DPI tests invalid.
DPI Tips
Native Steps
Stick to native sensor steps (e.g. 400/800/1600). Interpolated high DPI introduces jitter and noise.
eDPI Concept
eDPI = DPI × Game Sens. You can achieve same eDPI feel with different DPIs by adjusting sensitivity.
Recalibrate
Actual DPI changes slightly with different mousepads (e.g. cloth vs glass). Recalibrate when changing pads.
Avoid Excess
Unless for 8K multi-monitor work, avoid DPI > 3200. It amplifies hand tremors.
