I don’t think bubble size is the right thing to measure; instead you should measure the amount of contract you have with people, weighted by time, distance, indoor/outdoor, mask-wearing, and how likely the other person is to be infected (I.e. how careful they are).
An important part of my mental model is that infection risk is roughly linear in contact time.
