I follow the following light modifier size rule:
optimal camera to subject distance equals or less than sum of linear dimensions of the light modifier
i.e. for 80 cm x 80 cm square softbox optimal distance to subject equals or less than 1.6m
for 1.2m octagonal , deca hexagonal or round softbox optimal distance to subject equals or less than 2.4m
therefore for the 40cm large round softbox optimal distance to subject is 80cm only. 1.5m is not ideal and really pushing it but I would say somewhat acceptable in run and gun situations.
at US$7.37 price level you might as well give it a go

I just checked the specs - it's 12". Maybe those extra 4" of the Neewer modifier will make a difference. IMHO they should have made a 7' disc - no compromises LOL!
I never thought about the actual numbers, but I think yours make sense.
At $7.37 the 16" Neewer is definitely worth trying!
