    Use the preview to understand your inputs

    The slider changes a shaded circle around the stick’s centre. Your original X and Y readings remain visible. It does not apply a deadzone to your controller, operating system or games.

    Rotate each stick slowly through a full circle. The session records the furthest radius observed in 16 angular sectors. A sector counts as covered after reaching a radius of 0.75; this is a practical coverage marker, not a controller specification or pass/fail threshold.

    Round and square stick ranges

    Some mappings describe an almost circular range; others reach farther diagonally. Values beyond a radius of 1 can occur when both axes approach their individual limits. A perfectly round trace is not a universal requirement.

    For a repeatable comparison, use the same browser, controller profile and connection. Read the measurement method.
