I wonder how many people would have no idea how big a VHS tape is.

Our family had one of the early consumer VCR/camcorders around 1980. I still had to go grab one out of an old box to see how good my memory of its dimension is. Answer: meh, kinda close, but not an accurate unit of measurement even for a guy that used them from the beginning. And that’s because even old people haven’t touched one in a good ten years.

But, hey, Stranger Things, amirite? We’re all 80s-ophiles or something.

Personally, I would have gone with "the size of a trade paperback". Or maybe "the size of a large hardback book held with the arm fully extended."

Honestly it sounds really small. Not sure how you could have a viable product that only works in a small rectangle in the center of your vision.
