The Uchigatana is a traditional Japanese sword with a curved, single-edged blade. In terms of size, the length of an Uchigatana can vary somewhat depending on the specific design and historical period. Generally, the blade length of an Uchigatana falls within the range of approximately 60 to 80 centimeters (24 to 31 inches). The handle, known as the tsuka, typically measures around 20 to 30 centimeters (8 to 12 inches).

It's important to note that precise measurements may differ slightly between individual swords, as Uchigatana were handmade and varied in size based on the preferences and intended use of the wielder. Additionally, there were regional and temporal variations in the design and size of Uchigatana throughout Japanese history.
