What is dimensions of a lightsaber?

As an AI language model, I don't have any specific information about the dimensions of a lightsaber. However, it is typically portrayed as a cylindrical hilt approximately 25-30 centimeters (10-12 inches) in length, with a blade that can extend up to 91 centimeters (3 feet) long. The diameter of the hilt varies depending on the size of the user's hand, but it is generally around 3-4 centimeters (1-1.5 inches). The blade is typically depicted as being incredibly thin, often less than a centimeter in diameter, but emits a bright and intense beam of energy that can slice through almost anything.
