Enterprise's guidelines is

    Bumper Damage IS: Dent/scratch larger than 6” (size of the damage evaluator), or hole/tear of any size

    Exterior Body Damage (Non-Bumper) IS: dent/scratch larger than 2” circle, or hole/tear of any size

    Glass Damage IS: Any ‘Star’/crack

I suspect companies like Europcar, Hertz etc would be similar.
