/ic/ - Artwork/Critique

I have kind of a dummy question more suited for people who like manga
So for line weight, do mangaka keep the minimum and maximum brush size generally close together all the time or is this a thing thats changed often? Sometimes it feels like the brush I try to use is way too small so I crank it up, then sometimes its a bit too big, and it also needs some leeway for tapering
I dunno if anyone will understand my autistic question, its just something thats been bothering me regarding digital artwork
