So the diagram actually isn't on the floor. It's on a table. The table is in a room with high enough ceilings that you can stand on top of the table if you so choose, but why would anyone do that? Chanai, who is alternately sketching the vaguely circular array he wants to use for a spell and using the space around the edges of the same paper for notetaking, is sure not expecting anyone to stand on the table.

"Ooh, do you have another planet in your solar system ballpark this size? I could terraform it!"
"If you want it to hold its own atmosphere and take less than six months for a bunch of earthquakes from adding new stuff to settle down, it can't be too much smaller than 75% of this one. Bigger than this one might be okay too, people'll just feel heavier on it and there's less I can do to adjust it."
"It... does sound like it would take a long time. Do you want me to point out the planets in the sky tonight?"
"Sure, and if you don't know how big they are I can figure it out by making proportional models."
"...Uh, I don't know how to tell you without you having any idea how long a day is, but watch the sky and notice when it looks like the sun is going away under the earth."
"...right, what I mean is, I don't know what time of day it is right now, as I have been here less than a day and don't know which direction is north."
