While there are pro players who have high Valorant sensitivity settings, most players prefer lower sensitivity. This is true for not just Valorant but any competitive shooter out there. You can use cm/360 as the common unit of measurement regardless of what game you are playing. It dictates how many centimeters of hand movement you need to do to turn 360 degrees in-game.
Most pro players have anything between 25-50 cm/360 as their ideal sensitivity. CS:GO pro S1mple has a sensitivity of 33.6 cm/360, while Fortnite player Ninja uses 29.4cm/360. You do not need to measure your mousepad's distance as your muscle memory can easily recall what your “natural” sensitivity feels like. You can use this handy toolto convert your sensitivity across multiple games.
Pro players use lower Valorant sensitivity settings because the wrist is far less accurate than the whole arm. Lower sensitivities allow you to use your whole arm and make more extensive and more comfortable strokes at higher accuracy. It is also easier to flick your arm, but you also need a large mousepad and sufficient desk space. Higher sensitivity is preferred if you have limited desk space and have good aim using your wrist. If you feel more comfortable using high sensitivity and feel that you are happy with your aim, there is no reason to swap your sensitivity.
