What is the blade length and overall size of a typical odachi sword?
Updated Feb 2026
A standard odachi sword in this collection has a blade length of approximately 90 to 120 centimeters and an overall length including the handle of 140 to 180 centimeters. This places the odachi in the category of a great sword by the standards of any historical tradition - it is a two-handed sword that exceeds the dimensions of a longsword and approaches the scale of some great swords in the European tradition. The handle of an odachi is correspondingly longer than a katana handle, typically 30 to 40 centimeters, to provide the two-hand grip needed to manage the blade's weight and leverage. The saya of an odachi is equally long, making the sheathed sword a significant object that requires appropriate storage and display planning. At full length, an odachi in its saya displayed horizontally on a stand takes up approximately 150 to 190 centimeters of horizontal space, which should be accounted for in any shelf or display planning.
