The sword used by Uma Thurman's character, Beatrix Kiddo (The Bride), in the movie Kill Bill is a katana, a traditional Japanese sword. The length of a katana can vary, but typically it has a blade length of around 60 to 73 centimeters (24 to 29 inches). The overall length of a katana, including the handle, known as the tsuka, and the blade, known as the nagasa, can range from approximately 100 to 110 centimeters (39 to 43 inches).

In the context of the movie Kill Bill, the exact length of the sword used by The Bride may have been customized for filming purposes, and it's worth noting that movie prop swords can sometimes differ from real-life measurements. However, in terms of design and appearance, the sword used in the film resembles a traditional katana, which falls within the general length range mentioned above.
