Take a look at Ben’s Instagram page. There’s some good photos he’s posted showing the size differences folded up between the two. It sounds like though that it’s mostly for east of storage in which case a slightly larger footprint sounds fine. I was just cautious as when taking it on the train the 16” fits well into the end of carriage luggage bays and wasn’t sure how the 18” would fit here
