Sensitivity measurement guide

A practical guide to centimetres per 360-degree turn

Centimetres per 360, written cm/360, describes the physical mouse distance needed to turn the in-game camera through one full rotation. A setting of 40 cm/360 means the mouse travels 40 centimetres for a 360-degree turn.

Why cm/360 is useful

Raw sensitivity numbers use a game's private scale. eDPI improves same-game comparison, but it still includes that scale. cm/360 translates the result into a physical distance, so it is easier to compare two games or verify that a configuration changed as expected.

A larger cm/360 number means lower sensitivity because the mouse must travel farther. A smaller number means higher sensitivity.

How to measure it manually

  1. Open a quiet practice area and choose an unmistakable reference point.
  2. Place the mouse at one edge of a measured ruler or tape line.
  3. Aim at the reference point and note the mouse's starting position.
  4. Move horizontally until the view makes exactly one complete turn and returns to the reference.
  5. Measure the distance between the starting and ending mouse positions.
  6. Repeat at least three times and average the measurements.

Use a long, straight movement. If your pad is too narrow for one full turn, measure a 180-degree turn and double the distance. Avoid lifting the mouse during a measurement.

Sources of measurement error

  • Stopping slightly before or after the original reference point.
  • Moving in an arc instead of a straight horizontal line.
  • Mouse acceleration or a game profile that changes input behavior.
  • Zoom, aim-down-sights, vehicles, or scoped modes using different multipliers.
  • Measuring on a surface where the sensor skips or loses tracking.
Measure the mode you intend to compare. Hip-fire, ADS, and scoped sensitivity can each have different turn distances. Do not mix them in one record.

Moving a feel between games

First measure cm/360 in the source game under a consistent hip-fire mode. In the destination game, adjust sensitivity until the same physical distance produces a full turn. This preserves horizontal turn distance, but it does not guarantee identical visual feel.

Field of view, aspect ratio, camera projection, zoom behavior, weapon handling, and movement speed affect perception. Some players therefore match monitor-distance behavior for scoped modes instead of preserving a literal 360-degree turn. There is no single conversion that makes every part of two different games feel identical.

Choosing a range

There is no universal best cm/360. Available pad width, role, game pace, posture, comfort, and experience all matter. Start with a distance that permits an intentional large turn without forcing you off the pad, while still allowing small corrections. Then test small changes.

Record the setting, cm/360, date, and a short note about comfort. A written log is more reliable than changing values repeatedly based on one good or bad match.

How Test My DPI uses turn distance

The browser tool asks you to sweep across a marked lane and blends an estimated comfortable distance with tracking and acquisition results. Because browser coordinates are not a direct physical ruler, treat that output as a heuristic. A manual in-game measurement is the better final check.
