What does lengthwise mean?
Lengthwise is an English directional word meaning in or along the length of something rather than across its width. It is especially useful when instructions concern a long object whose orientation or direction matters, as in preparing food, cutting material, arranging seats, or packing an item. The word is common in American English and is also understood in British English, where lengthways is often preferred. Lengthwise is neutral in tone and can describe either movement or the orientation of a cut, fold, arrangement, or measurement. In everyday discussion it is less frequent than the fuller phrase “along the length,” but in recipes, manuals, technical writing, and product descriptions it conveys the needed direction compactly. Its transparent formation from length and the suffix -wise makes it easy to interpret and remember. Although it can function like an adjective before a noun, its main contemporary use is as an adverb, especially as a precise counterpart to widthwise or crosswise.
In or along the length; in the direction of the longer dimension.
"Slice the loaf lengthwise."
This is the word's predominant modern use.
Pertaining to or oriented along the longer dimension of something.
"The recipe calls for a lengthwise cut of the pastry."
This attributive use is less common than the adverbial use.
Lengthwise follows its built-in compass: if something is lengthwise, the long side is doing the talking.

Where does lengthwise come from?
Lengthwise is an English compound formed from length and the productive suffix -wise. Length derives from Old English length, while -wise continues Old English wīsan, meaning “in the manner of”; the compound thus expresses direction along the length. Lengthways is a parallel formation, and lengthy and lengthless continue the same English root.
