Try this:  Sit on the floor in the position you expect to hold in your
sub.
Measure the longest vertical or horizontal distance.    You'll surprised.
I found that I could fit into something about 34 inches in diameter.

But I'd like to be able to move a bit.

I looked at patents for balloon capsules (anyone else remember that?).
They were about the size I figured as my absolute minimum.
