Sizes

[A/N :- The sizes of stuffs in Naruto is very inconsistent so this is what I'd be using]

Full Kurama - 350m

Half Kurama - 100m

Other Bijuu - 100m (Since they were all the same size as half Kurama)

Peak Madara Susanoo (from canon) = Full Kurama (We saw that already)

Naruto and Sasuke Kurama Avatar and Susanoo - 100m (Naruto TL)

Naruto and Sasuke Kurama Avatar and Susanoo - 350m (Boruto TL. Kurama is complete now so I expect his size to increase too + Sasuke is shown to have the same Susanoo size as Naruto's Avatar)

Juubi = 700m = Hagoromo Susanoo (Filler though)

In this FIC current TL (It would increase as they get stronger)

Madara Susanoo - 100m

Indra Susanoo - 250m
