generally speaking, the doorway is facing the aisle.

aisles are generally longer, that is, the passage length is longer than the object length.

suppose the object is rectangular, the length is a, and the width is b.

The thickness is not considered first.

the doorway is C, and the aisle is d.

You can find the rule by drawing the floor plan, or you can find two building blocks to simulate it.

that is, comparing triangle areas.

it can be concluded that.

as long as ab <: A cd will do.

formula judgment can be brought in.

of course, the premise is that the width of the object is smaller than the width of the door.

the above is the general situation, regardless of the thickness of the object, and the situation that the goods are inclined up and down to enter the door, but like a heavy piano, you can judge it like this.

in fact, the thickness only needs to be less than the height of the door. Then you can pass the above judgment.
