The way I was told to check is to do this:

When wearing trousers with a belt and a T-Shirt, measure from from the lower edge of the belt at the front, over your shoulder and down the belt at the back.

Take the measurement while inhaling.

Under 110cm - Medium Counter Lungs.
Over 110cm - Large counter lungs.

Unless you are extremely tall go for the medium lungs. The large lungs are way to big for most people.

I'll second that - I'm a pretty big chap (196 cm, 110 kg) and have the large lungs. I also happen to have a set of medium lungs on one side (for my wife) and am seriously thinking of trying them out myself.

I have been told that all the lung sizes (including the now not-available small) are big enough for even the biggest person's lung capacity. The size differences are to make sure that the controls are in the right place.

I also agree mostly anyone will be fine with mediums. I'm 6' tall and 200 lbs. I have used medium c/l on the inspo classic and evo. If you were very tall it would probably be a little easier to access the man dil and 02 inflators but I doubt this would be a big problem. As far as loop volume, I doubt there are many human beings that would actually require the loop volume of the large. I can't come close to depleting my mediums even when half full.

I think given your height you would also find the large c/l too long and cumbersome.

I weigh a little less then you (95) and i'm the same height and i use the medium lungs. Had large ones at first but tried the mediums and found them to be much more comftable.
