Indeed... 100 cm Nagasa seems to be the max length for Tachi. Later, they made shorter Swords because they were more practical for armored fighting and inside buildings. The katana is better for infantry, while the Tachi was mainly for cavalry and ceremonial purposes. Though the mount can be changed, it does not change the blade's design.

Oodachi are at least 90cm, average is 120cm to 150cm. Hotarumaru is a verry long Tachi, but a dwarf Oodachi. ^^'
