What does breadthwise mean?
Breadthwise is an adverb meaning from one side to the other, or in the direction of the width of an object or area. It is especially useful when orientation matters: a panel can be placed breadthwise, a strip can be cut breadthwise, or two surfaces can be compared breadthwise. The word carries a neutral, slightly technical or descriptive tone, so it is common in instructions, design, engineering, and spatial description, while across is often the more familiar everyday choice. Although breadthwise can look unusual because it combines an abstract noun with a directional suffix, its meaning is straightforward: breadth is the dimension from side to side, and -wise specifies direction. It should not be confused with lengthwise, which means in the direction of the longer dimension. Breadthwise is also close in meaning to sideways and crosswise, though it tends to imply alignment with the width rather than simply a sideways movement.
adverbFrom one side to the other; in the direction of the width of something.
- In or across the direction of the width of an object, area, or surface.
"The technician rotated the panel breadthwise to align its edges with the frame."
"Fold the sheet breadthwise so that it fits inside the envelope."
"The two samples were aligned breadthwise for comparison."
Breadthwise points across the short dimension, while lengthwise points along the long one—a small suffix that keeps big things oriented.

Where does breadthwise come from?
Breadthwise is formed from breadth and the productive suffix -wise. Originally associated with a noun meaning way or manner, -wise developed adverbial senses meaning in the manner of and in the direction of. Breadthwise therefore literally means in the direction of the breadth and came to be used as a general directional term equivalent to across.
How breadthwise is actually used
