Calculate your centimeters per 360-degree turn. The universal metric for comparing mouse sensitivity across all games and players.
Enter your current DPI and in-game sensitivity to calculate how many centimeters you need to move your mouse for a complete 360-degree turn.
Keep your cm/360 consistent across games to maintain muscle memory for large movements like 180° flicks.
CM/360 (centimeters per 360 degrees) is the universal measurement of mouse sensitivity in gaming. It tells you exactly how many centimeters you need to move your mouse to complete a full 360-degree rotation in-game. Unlike DPI or in-game sensitivity values which vary between games, CM/360 is consistent and comparable across all titles.
CM/360 is the most practical way to understand and communicate sensitivity because it's physical and intuitive. When a pro says they use "30 cm/360," you immediately know they need to move their mouse 30 centimeters for a full turn. This makes it easy to compare settings, maintain consistency across games, and understand if a sensitivity will fit your mousepad.
CM/360 is calculated using: (2.54 × 360) / (DPI × Sensitivity) = CM/360. The formula converts inches to centimeters (2.54) and accounts for a full rotation (360 degrees). Your effective DPI (eDPI = DPI × Sensitivity) determines how far you need to move your mouse physically to achieve that rotation.
The beauty of CM/360 is that it works identically across all games. Whether you're playing CS2, Valorant, or Apex Legends, 30 cm/360 always means 30 centimeters for a full turn. This allows you to maintain consistent muscle memory for large movements regardless of which game you're playing.
Your ideal cm/360 should fit comfortably on your mousepad. Aim for your cm/360 to be 60-80% of your mousepad width. For a 45cm mousepad, target 27-36 cm/360. This gives you room for full rotations without constantly lifting your mouse.
Tactical players and snipers often prefer 35-50 cm/360 for maximum precision. Aggressive entry fraggers might use 25-35 cm/360 for faster reactions. High-mobility game players (Apex, Fortnite) sometimes go as low as 20-30 cm/360.
Once you find your comfortable cm/360, keep it consistent across all games. This builds universal muscle memory. You can make minor game-specific adjustments (±5cm), but major changes will reset your muscle memory.
Fast turns, minimal mouse movement, small mousepad OK
Hard to aim precisely, more wrist strain, overshooting common
Fast-paced games, aggressive players, Fortnite builders
Good balance of speed and control, versatile
May need medium-large mousepad
Most FPS games, all-around performance
Excellent precision, smooth tracking, less hand fatigue
Slower reactions, large mousepad required
Tactical shooters, long-range precision
Maximum precision and control
Very slow turns, XL mousepad mandatory, need to lift mouse
Snipers, extreme precision players
Tactical shooters favor low sens
Balanced for precise aiming
Higher for fast movement
Medium-fast for tracking
High for building mechanics
Measure your mousepad's usable width in centimeters. A standard gaming mousepad is 36-45cm wide, while XL pads can be 90cm or more. Your target cm/360 should be 60-80% of this width.
Begin with 30-35 cm/360 as a baseline. This is the most common range among pros and provides a good balance of speed and precision for most games. Use this calculator's "Find Sensitivity" mode to get the exact DPI/sensitivity combo.
Spend 20-30 minutes in deathmatch or aim training. Test tracking moving targets, flick shots, and 180° turns. If you consistently overshoot targets, increase your cm/360 (lower sensitivity). If you can't turn fast enough, decrease your cm/360.
Adjust your cm/360 in increments of 2-3cm at a time. Give each adjustment at least a few hours of play before changing again. Making drastic changes will prevent you from building muscle memory.
Once you find a cm/360 that feels comfortable, stick with it for at least 2-4 weeks. Muscle memory takes time to develop. Resist the urge to change your sensitivity frequently - consistency is more important than perfection.
