The debate is gonna always be bewteen FRinches and IMP inches.
I will suggest at a post mortem measured length ! of 1m68 he's over average length.
As long as he appears shorter than a guardsman/chasseur a pied en bonnet a poil it's gonna look right.
Academics, please stop arguing.
As long as he looks Thin in the revolution,
majestic and imperial as consul,
and looking a bit middle- aged in his middle age,
it doesn't matter.
1m 86 is 5'7" so that's it
My dad used to say if you wanna get ahead get a bigger hat !
