A term for “number of columns” of a matrix

Is there a single English word to denote the “number of columns” of a matrix?

For example, “dimensionality” of a 2\times 3 matrix is 2\times 3. I need a term for 3 in this example. I can always just say “number of columns”, of course, but could I have a single word for it?


There is a concept of wide and narrow data, so maybe you could use the term „width“ for the number of columns after you define it in order to avoid the ambiguity.
