It’s an interesting observation. We observe the world in landscape because our eyes are positioned to give us a goid balance between binocular vision and seeing predators in our peripheral vision, but most of our interactions are portrait, I suspect due to our upright posture. Most of the instances you mentioned are with things that either are, or are evolutiobs if things that were, designed around the fact we are talker than we are wide.
It would be interesting to observe whether animals with a different posture interact differently.







My kids have a pile of cardboard screws that they use to turn boxes into all sorts of things; rockets, forts, cars and you could probably make organizers, shelves and the like too. The screws grip the cardboard surprisingly well, and it’s easy to make even quite large structures robust.
