What are the typical dimensions of an odachi compared to a standard katana, and why does size matter
Updated Feb 2026
Standard katana typically measure between 100 and 110 centimeters in overall length with blade lengths of 60 to 73 centimeters. Odachi significantly exceed these dimensions, with overall lengths commonly reaching 130 to 160 centimeters and blade lengths of 90 centimeters or more. This size difference has direct practical implications for display planning. A standard katana fits comfortably on most horizontal sword stands and can be displayed on shelves or in cabinets. An odachi generally requires wall mounting or a dedicated floor stand, as its length exceeds what typical horizontal stands can support. The extended dimensions also mean you need to plan wall space accordingly — allow at least 170 centimeters of horizontal clearance for wall mounting with the saya. The payoff for this space investment is dramatic: an odachi on a wall creates a visual anchor that defines the character of the entire room, drawing attention in a way that smaller swords simply cannot achieve.
