plate armor makes you wider. weight and movement don't matter if you are too wide to walk up the stairs. I too have been jn these stairs, and wearing a t-shirt as a 5'8" male, I have about 2 to 4 inches of clearance. I would imagine a fully armored person taking up that small amount of empty space easily.

I took as kind of implied that we weren’t talking about “doesn’t physically fit on the stairs” because that wouldn’t be a very interesting assertion to make.

I imagine 5-10cm is enough, at least to the point you can wrangle yourself up the stairs, but you wouldn’t be fighting there in the first place with that amount of space.
