Did you by any chance switch "vertical" and "horizontal" at every point in your comment?

[fwipsy]

The words are intrinsically ambiguous. A standard fridge opens horizontally but stands vertically. Is it vertical or horizontal?

[decimalenough]

Horizontal vs vertical is determined by the orientation of the object's longest dimension. Portrait pictures on a wall and fridges with doors that open out are vertical, landscape pictures on a wall and chest freezers are horizontal.
