I do portable location work for portraits. My light modifiers, backdrop, stool, light stands, black window blocking sheets, sundry a clips, gaff tape, etc all go into a 400mm x500mm x 1200mm foam padded nylon flight bag. My heads, accumulators and batteries go in a second (heavy) suitcase style case.

I ould not worry about the size of your modifiers until the rest of the supporting kit;'s needs are worked out.

That said, yes, they are inter-related, so some iterations are needed before modifiers, light sources, and stands all suit one another and the format in which you are working.
Thank you for you reply. I like canadians, using millimeters!

I will work in either MF or LF for this. I saw elinchroms octabank, it looked pretty slick, like a big umbrella. That would be ideal. It comes with a non-ideal price tag though.

I will use a portable 640 WS battery flash. I need a big light source to produce an even, low intensity light. I want to shoot quite open. I think a diameter of around 1500-1800 mm would be good.

I tried a soft box of this size. It was not pleasant to work with. I was hoping there would be some kind of umbrella style octaboxes intead. Also gives a nice catch light.
